I've shot two rolls in 120 a cam so far and I am officially sick of trying to do it! I got a couple decent (usable) snapshots, nothing artistic. The experience of handcounting was interesting (to me anyway).
I'll leave the rest of the 220 in the fridge until I find an orphan 220 back to hack onto a crown graphic...I guess I'm still not looking for the easy way out. Or maybe a panoramic crude-cam with handcounting and NO red window. I bought some real film with paper behind it while I lick my wounds.
