I recently started taking a b&w photography class. I just developed my first two rolls of film, Kodak TRI X 400. And to my surprise about half to a third of my photos only came out. It seems that one shot came out then about 5 shots there is completely nothing. The film is almost clear, its kind of milkly blue. I also took a roll of fugichrome 100 for E6 printing and the same thing happened. I have a canon 35 mm rebel XS and I put the correct ISO for each type of film. The lens cap was off, I did not use flash for any of the pictures and the camera did not seem to have a problem calculating the right number of exposures. I just want to know if it might be the camera that is to blame or I am doing something wrong.
