Canon EOS Rebel G 35mm film Questions

I found your examples to be easy to fix, so it is hard for me to think that anything serious is wrong with your camera. ( I used a level curve, pulled the black level from the lower left to the base of the histogram, moved the white level, from the top right, left along the top closer to the right edge of the histogram, and then I pulled down the middle of the level curve until the white haze was gone.) The most needed is perhaps some compensation for the shutter calibration, which must be found out by experience with the camera.

Please send your work to a better film processor.
