- great, I think ERC is the way to go. Found a tutorial, seems straight forward enough....... 1) I can't believe that have have to edit the cr2 file to stop things deforming...Argh 2) "You could script that in Python with a parameter callback." do you know of a tutorial for this? is it straight forward enough? Thanks again
