Ok so i have developed negatives. I made the contact sheet. The negatives looked in focus then when i made a print it was not out of focus that bad but it was a bit. This happens with my other negatives too. My professor said they were out of focus. I take forever focusing the camera just to make sure i get it. I am not sure what is going on. Anyone got any ideas? I have 5 prints due next tuesday and it is my first critique so I would like them to be in focus as good as possible.
