Regarding the orange mask of film issue, you can set a custom white balance using a blank bit of film. Still lots of curve adjustment but you could make a profile of sorts for batch processing them to the point where it gives you an easy place to start.
Yea I figure one needs to make a profile or PS adjustement layer for each film type..
..curious to read what people find out works well regarding this!
Light leaks on the Rolleicord, meh.
Only on one of the 12 frames though, do not understand.
