This is what I love about old cameras and film. You can't plan this type of old feeling you get from this type of combination. The random combination of film age, film type, developer, fix, fix age, fix duration, developer duration etc. etc. all add up to a look that makes film special. You can photoshop all you want but you're not going to get the same happy accidents you do when you play with the real thing.
So I modified a Kodak No. 2A Folding Autographic Brownie so that it would take Fuji instant film. Lots of electrical tape and a few tests later I worked out the 3 fstop settings and the basic focal lengths. I've not shot a lot with it yet but as it's a bellows camera a thought occurred to me while trying to shot with it this weekend. If I could some how take the thing off it's rails I might be able to twist the lens around a bit and get something different. So I now have a very random tilt shift lens. Took several shots to get one steady enough to use.
