Using my recently purchased Yashica 200-AF I began photographing various scenes I had contructed using fruit and stuffed animals. I finished off the my roll of film by having my brother model before the camera. I excitedly took my film off to the photo place at the mall and I spent the whole night giddy with anticipation. When I finally went to pick up my photos the photo clerk looked like she was about to give me some bad news; and she did.. She showed me my negatives and they were all blank. She said something about needing to replace my batteries; but that didn't seem to make sense because I consistently heard what sounded like the motor in my camera advancing the film. Needless to say, I was bummed out. When I went to change the battery I naively thought it used regular alkaline batteries, but of course it required a lithium battery that costs around 30 bucks from Radio Shack. Before I blow $30 I wanted to see if anyone has a different theory as to why my pictures didn't show up on film. I mean, even if the batteries are weak, the shutter was openning any closing, so shouldn't I have had at least one photo shown up?
