I have just put on the downloads page of my website a free pdf long exposure calculator chart
Just download it, print and laminate it for use in the field.
I hope you find it helpful.
I plan to add some other free downloads so please sign up for my email newsletter for advanced notice of these – just use the form on the right hand side of this page.
