I remember I used to get contact strips in my early black and white days; without an exposure meter, it wasn't worth getting full prints of all the shots. I used to paste the strips into an album that I still have. I thought I had scanned a few pages of the album, back when I first started scanning old photos, but I can't find the images; they were pretty unhelpful and I may have just deleted them (you couldn't tell if an image was slightly out of focus, for example).
If I get a commercial scan I usually get back a CD with a contact sheet on it, but being the size of the CD, it's not that useful. So I think to do it, I'd have to fiddle around with Aperture. Not sure how; I did think of doing a screen grab of a contact sheet view, but there would have to be a better way.
I'm struggling a bit with what we might learn from other folk's contact strips in this way?
