hi!
i’m kind of embarrassed to say - i import the files into photoshop as layers, then line them up by hand and by eye. i hesitate to go into the method further, because i’m sure there are better, automated ways of doing it. pappubahry was always good at that sort of thing - he doesn’t seem to be active on tumblr at the moment, but you might be able to catch him on twitter.
if you are going to align images in photoshop, my method to align images A, B, C, D, etc., is to invert image A, then set the opacity of B to 50%. this makes any matching areas a neutral grey, and any non-matching areas (e.g. under- or overlapping edges) appear as black or white. then nudge or transform B until the black and white areas are minimized and the images are aligned. set B back to 100% opacity and repeat for C, D, etc. don’t forget to invert A back to it’s original form when you’re done.
again, i wouldn’t recommend the method - there are sure to be bits of software that do the same thing at the click of a button - but it’s what i do, and it might be useful sometime!
thanks, as always, for getting in touch.
regards,
b.
