Saundra Kay Spencer's complete testimony is available on the internet. Among the other reasons she didn't think these photos were the ones she developed is that the room were different, the lighting was different--the ones she developed were taken in an autopsy room with bright overhead lighting while she thought these photos were taken with flashbulbs. She apparently kept a log of what type of paper she was using at the time to print out photos and these don't match her log.

I just printed what I found most interesting, but would recommend anyone interested read her entire testimony.
