Creative Photography Webinars

I made three hour long videos for OnLandscape magazine in 2013 and they are now available via YouTube.

I have collected them together here for you to watch (and enjoy?)

Part I – a discussion of my creative/alternative technique images and approach (the echo on Tim’s mike is removed after about a minute)

Part II – A session filmed with me working live in the field showing camera techniques

Part III – The final video where I demonstrate my Adobe Lightroom and Photoshop techniques for processing these types of images

I hope you find these videos useful.

Shooting Landscapes Handheld. You Are Joking!

Handheld

Dark Light III – Taken handheld from Rannoch Moor.

I have written some time ago about my thoughts on working with what you’ve got. Basically, the premise of my mantra is, if all you have is a 50mm lens, then shoot with it. If its raining, rather than giving you he technicolor sunrise you envisioned, shoot the rain. You get the idea.

Recently, on the day I broke my leg in fact, I had to work to my own maxim. 

I was leading a workshop up in the snows on Rannoch Moor and Glencoe, in Scotland. On the first day of the trip, just an hour into shooting my tripod head broke. It broke in a major way (and kudos to Manfrotto for replacing it for me straight away once they saw what had happened).

I tweeted about the failure and many of my followers replied with sympathy (and we all like a bit of sympathy). Several said how angry I must be feeling and how it would ruin my trip. I could understand their point of view but I just didn’t see it that way.

Kit fails. You have to get used to that which is why I have back ups or alternatives with me for virtually everything in my bag, including tripods and heads. Except this time. This time I was car sharing and to save space the one thing I hadn’t bought with me was my spare tripod & head. Ironic, huh?

Getting angry about it would have just spoiled the trip, it wouldn’t have actually changed anything. Here I was in the most stunning of locations with amazing light. I was going to work with what I had.

So this meant shooting landscapes, often in low light, handheld. 

So how did I approach this? I was using the Canon 5d mk2 and was happy taking the ISO up to 800 (and in very low light I went to 1600 at times – whatever it took to get the shot). I also went wide with my aperture. So I abandoned my usual preference for f11 (or f16)  most of the time and went wider, right down to f2.8 at times in low light, but often working at f8, all with a view to keeping the shutter speed high enough to get sharp images.

If this hadn’t been possible I would have gone over to shooting ICM (intentional camera movement) images. Again, working with what I had. 

Another approach I adopted was to shoot in burst mode. Firing three frames at least for each image to give me a better chance one would be sharp. It meant I came away with nearly 900 frames fom the day, but it did increase my success rate.

I also moved to auto focus. On a tripod, I use manual focus in Live View mode which is perfect, but hand holding it just isn’t practical to focus manually all day. There is no benefit in it, in fact, auto focus is perfect for just this situation. I use centre point focusing so I have complete control over what I am focused on. So I turn on just the centre focus point. I then point the centre of the lens very precisely at what I want to be my focus point, press the shutter button half way to lock focus and hold it there, reframe and then complete the shot. You can also use the Focus Lock button on the back of the camera in the same way. 

I found I got the best results using my longer lenses, especially the 70-200 f2.8 IS L zoom. This stayed on most of the day. The image stabilisation helped with sharpness and I followed the basic rule of thumb that you need to keep your shutter speed faster than your focal length so I tried to stay above 1/200 sec all day, using ISO and aperture to do that.

Another advantage of using the 70-200mm (and the 24-70 f2.8 L which I also used on the day) was they both have long full tube shaped lens hoods. On the day, blizzards kept blowing through and these hoods really helped to keep snow off the front element of the lens.

When I came to review the images later (and trust me, I had plenty of time to review them, lying in my hospital bed) I realised that broken tripod head had done me a favor.

I had an extraordinarily high “hit rate” for successful images on the day. I took many more that I was happy with than I normally would. I found I was able to react really quickly to the fast changing light up there. As the blizzards were blowing through we had amazing gaps in the clouds with shafts of light and wonderful cloud shapes. On a tripod I would have been faffing about and couldn’t have got half the  images I did. 

I also would have been shooting much wider lenses, 45mm or 24mm, out of habit and on reflection, images at those focal lengths wouldn’t have had the impact I got from the 70-200 lens. (For my wider shots with the long lens I shot several panorama sequences, all handheld, and Photoshop stitches them perfectly. It’s amazing).

I would also have been more likely to have been trying to use my Lee filters. This would have slowed me down even more and with the falling snow caused frustration and even more lost shots.

Yes, that tripod head did me a big favor. Of course, looking at it another way. If it hadn’t failed I would have had it with me later when crossing the river and would have been using it to steady myself so maybe I wouldn’t have fallen and broken my leg… But let’s not speculate.

So, the lesson. If something fails in the field or you forget something, work with what you have. Think laterally. Work around the problem. Find a solution. It might feel uncomfortable, but just do the best you can. Getting angry with yourself or your kit, or giving up and going home don’t help, and you never know, like this occasion, you might just produce something unexpected by approaching the problem with a positive frame of mind.

If its something really bad like leaving all your batteries or memory cards at home, then use your mobile phone camera. If that’s back in the car, then just sit back and enjoy the sunrise. There will always be another.

How do I create light trail images?

light trails

Westminster by Night

Have you ever wondered how to go about capturing light trails? They look dramatic and add a dynamic feel to urban images and are easy to capture.

Before I go into technique there is an important factor about this image which lifts it above many light trail shots. The Sky. Its not just a case of shooting at night. In fact the ideal time is a short 15 minute period shortly after the sun has set. For architectural photographers and those after light trails this is the prime time to shoot. If you look at the image you will see the sky is not black, there is still some residual light (twilight) in the sky. In this brief period of minutes the light in the sky balances perfectly with artificial light which is why it is so perfect for capturing architecture and light trails. You can still shoot the light trails when the sky is black but the images won’t be quite as attractive. Have a browse of the finest architectural night photography and you will see the photographer works in this evening twilight period (or gets up early as a similar is experienced some time before sunrise).

Lets say you are in position at the right time. Get there well in advance so you can sort your composition out and get your exposure right before twilight. It is very frustrating to miss the brief twilight window becuase you weren’t in position and set up in time. Needless to say you need to be on a tripod with a remote shutter release. No graduated neutral density filters are needed as the camera can cope with the dynamic range of the image by this time. You may need a standard non-graduated neutral density filter (perhaps a 2-stop) to slow the exposure down if you are getting too short an exposure for the effect you are after (alternatively, you could use a narrower aperture, say, f16. I would avoid using f22 unless I was forced as the image quality will degrade due to ‘diffraction’, but thats another whole issue!)

For these images the lenght of the exposure is as important, if not a little more important, than depth of field. For my shot of Westminster I worked at f11 (which gave me sufficient DOF and kept me close to the sweet spot of the lens (around f8 would be about perfect). At ISO 100 (for the lowest noise possible), this gave me an exposure time of 4 seconds on my 24mm TSE lens. (As I was using a tilt and shift lens, I could have worked at f8 and used the tilt mechanism to give me the depth of field I needed but I was working quickly and didn’t want to complicate matters).

I test out several shutter speeds before the light gets to its best so that I am ready. The speed of the traffic and the brightness of the lights will dictate the length of exposure. Faster moving vehicles need a shorter shutter speed than slower vehicles. In my case, timing was vital. I could have shot when just cars were passing but I found it was worth waiting for a bus to appear as this gave a wider stripe of lights because of the upstairs windows. I fired the shutter, using a handheld remote release, a fraction of a second before the bus entered the frame. A few buses later, I had my image, the light dropped and it was time to head off for more night shots around London.

If you would like to master low light and night photography, why not join me on one of my London Night Workshops. We even have a London Black Cab to drive us around all of the best locations all night. Drop me an email if you are interested as these are selling out before I can list them on my website.

Tips for photographing in the rain

Rain Tips

Wet Day in the Forest

I am sitting in my studio with rain lashing down. April showers is one thing, but this is ridiculous! I thought it might be an idea to post my top tips on photographing in the rain.

Many photographers simply dismiss making images in wet weather out of hand, but in doing so I think they are missing out on some wonderful and different images. Granted, if  the rain is really driving and especially if it is blowing directly onto the lens, it is pretty much impossible to work outside. It is then I look for an indoor location or head home, fire up the iMac and do some image processing with some good music on and a nice hot cup of tea to enjoy.

However, we often get gentler rain or it is blowing in from behind us so the lens stays clear. It could be the rain is coming down vertically or is intermittent. In those circumstances it can be ‘game on’.

The first thing is to protect our gear. Whether we shoot on film or digitally, water and cameras are not a good mix. If our body and lenses are from a pro range, like the Canon 1ds and ‘L’ lenses, they are heavily sealed against water and dust and can perform in extreme conditions, but mid range bodies and lenses down, while having some weather sealing can soon start to be affected (often terminally) by water and dust. I have tried all kinds of camera protectors and to be honest, most are just impractical. At one end there are over designed complex polythene systems with arm holes and gussets, seals, elastic and goodness knows what that take a couple of days and a lot of patience to fit and are then so bulky and restrictive in their desire to totally protect the kit that operating the camera with them fitted is like trying to thread a needle with our hands submerged in a bucket of jelly.

There are other simpler protectors which are so flimsy they are worse than useless.

I do carry a couple of the disposable Optech ‘Rainsleeves’. These are low cost, come in packs of two and are designed to be used a few times and then thrown away. With careful use they can last quite a while. They take up little space in the kit bag and the price is very reasonable. It has to be bad for me to put them on though because, like most rain covers, they restrict us in using the camera. Everything becomes fiddly and a bit of a chore. The worst problem is getting your eye to the eye piece to compose and focus (or, if you use Live View, seeing the monitor clearly as the polythene is not optically clear enough to focus critically). There is a hole in the protector which is designed to go around the eye piece but to fit it you need to take the eye pice rubber off and then re-fit it over the polythene and by this time I am losing the will to live.

A simpler and much cheaper option is to carry a thick polythene bag. I carry one which is big enough to simply pop over the whole of my set up on the tripod. It covers camera, lens and filters. Obviously, you can’t work with this in place but it saves packing up for every shower. As soon as the rain has passed over, just whip it off and got on with the business of making images.

I also carry a cover similar to this one. Bought on EBay for less than £15 it gives good access to the cameras controls and is quick to fit and remove. Focusing and zooming are a bit tight but the cameras body controls are very easy to use, as is the eye piece and screen. I have been using mine for a couple of years and it is stills waterproof. Made from proofed nylon you buy one to fit each lens and body combination (in theory) but I bought one for my longest lens, my 200mm f2.8, and use it on all my lenses – the shorter lenses just have the cover a bit bunched up but it is not an problem for me.

Then, yesterday, on one of my bluebell wood workshops, a client had a new ‘device’ which seems like a brilliant idea to me (Thanks for the tip, Maria!). She was given the idea by photographer, Jeremy Walker. It may sound a bit strange but in really wet conditions yesterday she was able to shoot with ease and keep her kit dry. It was a very large sheet of Chamois leather. Told you it sounds strange. However, it is is not your average Chamois from Halfords. She got this from Skye Skynes – here on this page . Now, when you see the price (£22 delivered in the UK) you will probably have a sharp intake of breath and think I have finally lost my marbles, but before you shake your head and leave this post let me just tell you, these are the most amazing Chamois you have ever seen or felt. Skye Skyns make them from sheep skins on the Isle of Skye and they are very thick – many times thicker than the Chamois I use when cleaning the car. It is also the softest Chamois I have ever felt. The sheet is really big and you just drape it over your camera and lens. In between exposures you can drape it over the front of the lens (and filters) to protect the glass from drops of rain. It absorbs the rain and is perfect for wiping kit dry too. Because it is a sheet rather than something fitted you can double or triple fold it and just drape it over the lens and position it as you wish. As I watched my client work I was impressed with how easy it was for her. The Chamois has another advantage, it makes a great thing to wrap kit in to protect it. So even in dry weather it iso earning its keep in the rucksack. They are washable so when they get grubby they can be spruced up easily. I have ordered mine and can’t wait for it to be delivered, although knowing me it will come the day a long drought starts and I won’t get to use it in anger for months!

A good style of hat to wear in the rain is a hat with a rigid peak, like a baseball cap (but waterproof). This keeps us a bit drier and warmer but also the peak goes over the top of the camera while we have our eye to the eyepiece and helps stop the rain fogging the viewfinder. Absorbent lens cloths (and often several of them are needed for a rain session) are essential for drying fog off of the viewfinder and lens.

I also keep all those little bags of silica gel which come in many products packaging when they are delivered to us, you know the little white sachets with beads in which have ‘do not eat’ written on the outside. Silica gel absorbs moisture. I keep them all and drop a few in my camera bag, to help dry the air in the bag. Every now and then I swap them out, dry the old ones out at home and let the new ones do their job in my rucksack. (I also keep them in my laptop bag, lens cases and so on. Every little helps.

What about drying kit off after the session? I use absorbent cloths to dab the camera and lens dry, getting the worst of the wet off. I then let the kit dry slowly and naturally in a warm spot in the house, but not by direct heat. Then, once dry it needs a clean and polish to get any residue off of the body and glass. For cleaning my lenses I have stopped buying the ridiculously expensive lens cleaning fluid the manufacturers would like us to use. I get a big bottle of lens cleaner from my opticians for £2.75 (and that amount lasts me a couple of years!!). I use it to clean my glasses and honestly can’t see any difference when using it on my lens compared to the stuff sold by camera suppliers. I have a small spray bottle I decant some into to take into the field from the large bottle which stays at home.

That’s enough on keeping the kit dry. What about technique?

Passing Shower - Isle of Harris

Firstly, I don’t tend to use lens hoods for protecting against flare but I do use them to keep rain off of the lens. The two lenses I have which have particularly effective lens hoods are the Canon 24-70 L and the 70-200mm. Both of these come with a lens hood which is a full tube, not ‘petals’ which is more usual on wider angle lenses. These completely shield the lens glass from all but rain which is driving towards the lens in strong winds. The downside is that you can’t use Lee filters. To overcome this limitation I take bracketed exposures and blend them later in Photoshop. Problem solved.

I sometimes carry a golf umbrella which is useful to work under as long as there isn’t much wind. (This is the umbrella I use – designed for use in high winds – CLICK HERE) If the rain is coming in horizontally or the wind is strong, forget the umbrella, it is just impractical. I have been toying with the idea of trying studio lighting clamps to see if I can find one which will lock on to my tripod leg and hold the umbrella over me and the camera so that my hands are free to work. I will let you know if I find one that is suitable.

It makes sense not to fight the rain, so if it is blowing in from a particular direction, see if there are images to be made that will enable you to turn the lens away from the direction it is coming from. I also often head to woodlands in the rain. Trees in leaf will provide good cover although when the leaves get very wet it will start to get through to you, but it is dripping vertically from the leaves and not blowing in to the lens so with some of the protection I describe above we can continue working.

Cromer Pier - Winter Rain

So, there we are, all set up with a protected camera and some techniques to help us keep dry while we shoot. Is there any way we can use the rain to enhance our images? Most certainly.

The first thing to say is that the light as ‘bad’ weather passes or just before it arrives, is often spectacular. Foregrounds can be lit with glorious golden light with a deep black sky (one of the rare occasions that the sky is darker than the foreground). Shafts of light can pour from the clouds and glide across the land or sea. Rainbows decorate the sky. It is the photographer who is prepared to be out in the rain that gets to capture this glory.

In rain I often focus on making detail images, intimate landscapes. In woodland or in amongst the shelter of rocks there are lots of fascinating details which look great when wet. The diffused soft light when it rains is perfect for detail images as there are no strong shadows to contend with and the colours are rendered beautifully. The woods or rocks provide some cover and working on the close landscape provides a nice change from shooting the wider world.

While it is raining keep an eye open for things being back-lit. As the sun emerges from the clouds, wet trees, plants and buildings can glow as the sun catches the wet surfaces. If you want the opposite effect and want to kill reflections and saturate colours, fir a polarising filter and rotate it while looking through the eyepiece and see the reflections disappear. Shooting in the rain is also an ideal time for more creative image making – try shooting through wet glass from inside a car or cafe. The rain blurs the world and creates an impressionistic feel to things. Or go the whole hog and have a go at ICM (intentional camera movement) utilising the low light to lengthen the shutter speed and create images with blur by moving the camera.

If you like long exposures, try shooting them in the rain. If you can keep the kit dry, the effect of the long exposures is to turn the rain into mist and you end up with an image which looks like it has been shot on a misty or foggy day.

A final idea is to shoot puddles and running water. The raindrops create radiating patterns and often the light and colours above the water is reflected in it and yields great creative possibilities.

It has taken me a few days to put this post together. Now, as I finish it, the day is warm and bright. the rain seems a million miles away, but it is forecast again for tomorrow. I find myself hoping it will rain, so I can go out and have a go at capturing something with my camera. I hope you feel inspired to, too.

How do I create Panoramas?

Panoramas

Before getting in to answering this question I just wanted to mention I am running a “Capture-to-Computer” workshop in Skegness, Lincolnshire on Saturday 21st January 2012. One place is taken but there is one free place left. The basis of the workshop is creative and artistic photography – blur, ICM (Intentional Camera Movement) and textures. The morning will be spent with me showing you the techniques for shooting this style of image and then after a meal (included) I will spend the second half of the workshop showing you how to process these images in Lightroom and Photoshop. If you would like to book the second place the price is £149. Please drop me a message and I will organise it for you. Right, now on with the business of making panoramas!

I love panoramic images and with modern digital cameras and software they are easy to make. I find myself rejecting the use of super wide lenses in favour of making panoramas more and more in my photography. I am not keen on the heavy distortion that comes with the super wides and the converging verticals they create. With a panorama I can get in even more width and maintain a natural looking image with far less distortion.

You can by purpose made panoramic tripod heads, such as the Panosaurus, which are designed to rotate the camera on the ‘nodal point’. If the camera is rotated while held on this point and kept absolutely level will allow it to create almost perfect panoramas with little distortion and a very natural look. However the heads are expensive and you either have to have them fitted to a dedicated tripod or be prepared to switch heads in the field, and few of us are that dedicated or have the backpack space to carry two tripod heads.

There are two very acceptable alternatives which are ideal for most of us and I use both in my image making. I will cover both methods here. You can use a tilt and shift lens (the expensive but easier option) or you can use a standard prime or zoom lens. Both require stitching images together in software and both produce great images if done carefully.

So, if you want to make high quality panoramas, how should you go about it? The first step is to get your tripod as level as possible and make sure the camera is as level as possible on the head. This is far better than angling the camera slightly upwards or downwards. The more our of level the tripod and camera are, the more distorted the final image and the area you will need to crop away from the edges of the pano will be larger. I use the small round level bubble on the top of my tripod below the head to level the tripod itself. This can be fiddly as you need to tweak the leg lengths to get it right but it is worth doing. I then level the camera on the head using my hotshot spirit level.

Next is getting the settings in the camera right before you start shooting. It is critical that nothing changes between shots or you will not be able to seamlessly stitch the image. Turn off auto focusing on your lens so the focus point does not change between shots. Switch the white balance to daylight so it doesn’t alter between shots. Zoom out further than you want to to allow for cropping the stitched image which you will have to do to a greater or lesser extent. Don’t frame the image as you want it to finally appear as some of the edges will be lost. Start the panorama further to the left or right than you want to for the same reason. I use the camera in portrait orientation for panoramas to give a larger file size and more depth for cropping (unless I am using a tilt and shift lens, but I will come to that later).

Working in aperture priority or manual, choose one area of the pano to set your exposure and focus. The exposure is often the tricky part, especially around dawn and dusk or when the scene has high contrast. I tend to aim to set my exposure based on the area of the pano which is almost the brightest. I take a test shot to get the histogram across to the right. You have to accept then, that as the camera moves to wares the darker area of the pano it will begin to under expose but we can tweak this later in the software to balance the image. I set my neutral density graduated filters for the same frame as the one I use to set the exposure. You have to accept that as you take the other frames the positioning of the grad may not be quite perfect, especially if the land rises or falls across the width of the range of shots but it will look worse if you try and move the grad up and down for each image. (I prefer to use soft grads for panos to make the transition line less obvious).Do not use a polarising filter when doing panos as this will cause havoc with the look of each frame and you won’t be able to stitch the images acceptably. Focus hyper focally or on a point very close to the base of the frame. I usually use f16 for panoramas to give a bit more latitude on depth of field, whereas in my other landscape work I am usually trying to get the aperture to f13 or f11.

Once you are all set up rotate the camera to the left or right hand end of the pano sequence. Remember go further left, or right, than you want to include in the final image you have in mind. I then take a single shot with my hand in front of the lens with my thumb up. This tells me the next image is the start of a pano sequence. Once I have taken the final shot in the sequence I take another with my thumb down. This indicates the end of a sequence. Believe me, you will be pleased you did when you get home as it can be hard to tell which images are for panos.

Take the first shot and then rotate the camera for the next as quickly as possible. The absolutely critical thing to remember is to overlap each frame by at least 30%. It is better to overlap by 50% than to go lower than 30%. The more data and overlap Photoshop has to work with the better the quality of the panorama you will get. The reason for working quickly during the sequence shooting is to minimise movement of objects in the pano. Anything moving makes it harder for the software to do the stitch, so scudding clouds, branches of trees blowing in the wind and so on can cause issues.

Don’t forget, panoramas don’t have to be horizontal. For a really different type of image use the same system but shoot vertically. Vertical panoramas look great on the wall.

Back at home on the computer there is some very specific things you can do to make the panorama stitching go well. I use Lightroom to work on my raw files so the screenshots below will show that, along with Photoshop for the stitching but Elements works in just the same way although the menu items might be in slightly different places. You can also get specific panorama stitching software but I have never used this so can’t comment on it.

Import the raw files into Lightroom. Do not allow the import dialog box to apply any changes to the images on import such as adjusting white balance or applying some preset as this will make stitching difficult or impossible to do seamlessly. It is vital you don’t do any work on them whatsoever before they are stitched. Find the sequence of images and shift click to elect them (this is when the thumbs up and thumbs down shots are a big help, but obviously don’t include them in the stitch!). Right click the selected images and select Edit in >> Merge to panorama in Photoshop. (see screenshot below)

 

This will open Photoshop (or Elements) with the following dialog box open

 

On the left hand side select the Auto  radio button and in the centre area of the window you will see the list of raw files you are using. Click OK. Now just leave Photoshop to do its thing. It will take a while depending on how many raw files you are stitching and how fast your computer is. On slower machines you will have tome to go and make coffee :).

Once stitched the image will look something like this;

Now you can see why cropping is required. In the layers panel you can see how Photoshop has stacked the three images and then masked them to achieve the stitch. The next step is to flatten the layers and then crop the image to the panoramic shape, losing all of the irregular edges. I then save this image as a tiff (or psd, if you prefer) and take it back into Lightroom. Now you can start making adjustments to the exposure, contrast, clarity and so on because now it will be across the whole image and will look right.

Once you have made the adjustments you want in Lightroom, move the image back to Photoshop for any final tweaks and adjustments there, and you are done.

The process is identical with Tilt and Shift lenses, with a few differences. Firstly, when doing horizontal panos you keep the camera in Landscape orientation. You make the sequence of images by using the shift mechanism and make three images, one shifted all the way to the left, one in the centre position and the final one shifted all the way to the right. All the information above about levelling and camera settings still apply and the stitching process is identical, you just need the three shots. The advantage of this method is the overlap the TSE lens produces is way beyond 30% so the stitch works well and the amount that needs to be cropped away is usually less as the lens tends to give a clean stitch if the tripod and camera have been set level.

 

So, why not have a go next time you are out with your camera. They are great fun to make and can be quite addictive. Enjoy!

 

 

 

 

 

How do I re-size images for Alamy?

Many people how to get their images prepared for Alamy, especially their request for 48mb images. It is a bit confusing, so here is my method using Photoshop – but if you use Elements or some other software it may help you too.

The file you upload doesn’t have to be 48MB in itself – but has to be able to be converted by their customer to a 48mb TIFF.

This means you have to upscale the size of the file yourself before sending it as a jpeg.

To do this – Make sure you shoot in RAW (although jpeg, may work – it’s just I always shoot in RAW) and work on the image in Photoshop in 16 bit colour (which you will be automatically if you have opened the RAW file in Photoshop via Lightroom or Canon Camera RAW software) , cloning out dust, tweaking the levels etc (For stock libraries, don’t saturate the colours or do any sharpening – they want their customers to be able to do this to their own tastes/needs).

Then, when all is done, click the Image menu and select Image Size

In that dialog box make sure all three tick boxes are ticked and that ‘Bicubic Smoother’ is selected in the drop down box. Set the resolution to 300 pixels per inch (240 pixels minimum)

In the top width and height windows make the longest edge (depending on if the image is portrait or landscape orientation) around 5000 pixels – you will need to play with this figure to get the right length for your camera – the aim is to get the pixels dimensions figure at the top of the box to 96mb or above – but get as close to 96mb – as the higher you go the more chance there is of the quality deteriorating. Click okay.

Now click the Image menu again – select mode and select 8 bits

This will halve the file size (from 96mb to the magic 48mb). Now save in the normal way as the highest quality jpeg. The jpeg will vary in size depending on the type of image, how many colours in it etc and could be 8mb up to 16mb or more – but probably never above 20mb. The important thing is Alamy can now convert it back to a 96mb TIFF or PSD file for their customer.

I hope this demistifies the process for you?

And I haven’t forgotten I said I would do a tutorial on adding titles to your borders in Photoshop – it’s just this question came up from one of my students and as I had written it all down for him, I thought you could use it too.

Happy shooting!

How do I put a watermark on my photos?

I get asked this a lot by students so here is a post to provide the answer – it works in Photoshop or Elements (and the print and export modules of Lightroom have a custom function to add one also).

Watermarking your images is not a foolproof way to stop people using them without your permission. Some will ignore it and use it anyway. Others will spend a few minutes in Photoshop and remove it – with basic cloning skills it is usually not hard to do.

What watermarking your pictures does do is put off some who would steal your images and just emphasizes that it is against your wishes.

More effective is converting the image to 72ppi and reducing the size to say 1000 pixels on the longest side before uploading them. This makes the image unusable in any printed form. It will still display perfectly on a screen as these work at 72ppi – but printing will be useless. If you are using Flickr to display your images you can also switch off the ‘all sizes’ option in your account preferences which will make it much harder for people to steal your photos.

Anyway, on with the tutorial. There are two ways of doing this – by creating an Action or by making a Copyright brush. I tend to use the brush method.

1. In Photoshop create a new blank document. (click file, new). This should put a blank white page in front of you.

2. Next create a new blank layer

3. Select the Type tool to type your text – in my case I would then select a font and font size and type – Copyright 2010 © Doug Chinnery – (you can hold down the Alt key and type 0169 on the number keypad and this will inset the copyright symbol automatically)

4. When you are happy with it select the Rectangular Marquee tool by pressing the M key and drag a rectangle around your line of text.

5. Then go into the Edit menu and select ‘define brush preset’. When the dialog box opens give your brush a name (not a name like ‘Dave’ or ‘Debbie’ but call it Copyright Brush for example.) Then click OK.

6. Now in your brush presets drop down box you will find your copyright brush at the bottom of the grid. It will looked all squashed up but don’t worry, it will display correctly when you use it.

7. To use it, open a photo you want to copyright and add a new blank layer to it.

8. Select either white or black as your foreground colour – press D to set black and white as the foreground and background colours then press the X key to swap them if necessary. I use white mostly unless the image is very bright so white won’t stand out, then I use black.

9. Press B to get the brush tool selected and up on the options bar drop down the brush toolbox and click on your copyright tool brush at the very end of the set.

10. Use the [ or ] keys to make the brush bigger or smaller

11. Click on your image where you want the copyright info to be.

12. The in the layers palette on the blank layer with your copyright brush info use the opacity slider to adjust how the strong the brush is – you can really fade it out so it isn’t distracting or have it more prominent if you prefer.

13. When you are happy, flatten the image.

14. Remember to save the file with a different name so it doesn’t overwrite your master file – otherwise your original file will have your copyright info plastered across it – not good if you want to print it and hand it on your wall!!

I hope this info is helpful?

If you prefer to use Actions then record the above being done but instead of creating a new document just put a blank layer on a photo, type your copyright info, and set the opacity, flatten the image and then stop the action recording. Then it is just a case of running the action on future images – the only problem with this is that it will put the copyright info in the same place and at the same opacity on every image and sometimes this doesn’t look right., but the choice is yours.
