I've been using more film recently, and I have a lab develop and scan it for me. Then I post the results to a web gallery for sharing with friends and family. The same gallery also has photos taken with various digital cameras. In the gallery, pictures are automatically organized by date and time, which is nice since it keeps events in chronological order even if different cameras are being used. The problem is the film images. Since there's no date and time, I have just been batch timestamping them whenever I get back the scans from the lab. Going back and trying to remember when each picture was taken is laborious, and writing little notes that I'll lose before getting back the scans is just as bad. What I'd like is some sort of gadget that would just make a record of the date and time as I take each image. I'm flexible as to what it might be, but the smaller and more convenient it is to use, the better. Ideal might be a watch with a button that I could press each time I make a photo. Obviously the watch would need to have some way to connect to a computer for downloading the data at the end. A separate tiny device that I could put in my pocket would be fine. Or I suppose that I could switch to something like an iPhone and write a little application for that to do what I want, but I suspect that would be a little more cumbersome in operation. I am not averse to programming and even possibly building something myself, but if there's an already existing answer, I'd prefer that. Any suggestions?
