I am looking for a script for focus stacking with Raynox DCR 250. There is already default script there but it is linear and that is better suited to stock lenses and, with the Raynox 250 attached, I think it needs to exponential focus. Can anyone help me find such script or may be some setting with that default stacking script? I am using a Canon SX40.
I have just written a focus-bracketing script for closeup lenses, including the Raynox 250. Here is a link to my article, which contains documentation of the script as well as the script itself: http://www.dpreview.com/articles/9780512447/focus-bracketing-scripts-for-macro-setting-and-for-closeup-lenses Here is another link to some outdoor stacked images made using the script http://www.dpreview.com/forums/thread/3508821
I don't think you need to use a special "script". There are some softwares that do the trick and are easy to use.
If by any chance you're using photoshop, this guide will help you:
I was using it to stack 20 photos and it works great for me.
