Just finished up developing some rolls from the F3. Haven't scanned yet but based on looking at the negatives it looks like my F3 is okay for the most part.

For the shots I handheld metered, except for user error, my images came out exposed properly. However, the images where I used the cameras meter were mostly good but some were way off. My guess is that Im still not used to the spot meter of the F3 and will need to consider using the exposure compensation more for complex scenes. I consistently used the "exposure lock" button and it helped but only somewhat. When I use this camera again, it will probably be with a hand meter.

Also I slowed down my developing I that I was a lot gentler and slower when doing the rotations during development. I think this helped quite a bit but he scans will show if I'm right
