I recently started shooting using two old 35 mm film cameras (Minolta 7s and Olympus OM-G). Since all labs have been closed, I've been developing film at home using first Cinestill, then Arista's developing kits, and scanning using the Epson V-600.
Many of my photos have been coming out blue- or green-tinted (photo 1), and the Epson software has been able to correct some of them (photo 2), but not all.
I noticed that the last few photos in many of the rolls came out okay--i.e. not needing any color correction. When I looked at the film, I saw that that entire section of the roll was tinted a different color. I realized then that instead of being tinted orange, like most developed film should be, most of my film had been coming out greenish-blueish. The pictures where the film was tinted orange came out wonderfully, while those with an overall greenish hue ended up having the same hue.
Any idea what I could be doing wrong in the development process that the film comes out the wrong color in the end? I had very few rolls (maybe 3/15) come out the correct orange color, but otherwise they're all off.
