I can't believe I did that! I had a photo shoot saturday night for a group project I'm part of (actually, I was the one who organized it ) The problem was that none of us had any lighting equipment, and the location we had access to as a "studio" was rather dark. I'm used to shooting with 100 and 200 ISO film, so trying to get good shots of the models was a tough prospect, especially with 4 photographers stepping on each others toes. After trying to jury rig some extra lighting (and giving up) and firing off a roll of film (which I'm anticipating suffering from camera motion blur pretty bad) one of the other photographers tossed me a roll of 800 ISO film. I remembered to change the setting on my camera to 800 before shooting, and got some really good shots in (I think, I'll find out once I get the film developed) but then, when we switched to doing some still life shots, I switched back to 100ISO, and guess what I forgot to do? I fired off a whole roll of film with the camera still set for 800ISO film!! I tell you, I was growling at myself at that point. My question to everyone is, is there anyway to salvage those shots? Or are they a write off? I think there are some pretty good shots on that roll, and would like to salvage them if it's possible, but it's not like they couldn't be duplicated at a later date.
