Adding vitamin C was my idea to minimize the stain in Agfa APX400 which made the negatives unscanable but allowed to be printed in an enlarger. The stain is almost gone (depending on the film) but also the shadows get a small boost.
You did say that is TriX, do you have another Tri-X negative scanned, that should be a firer comparison
I tried it in several films and like other developers this one is a "honest grain"one and will only show whatever structure your film has.

1. thanks, yes the prints I had done do show less grain. Even at 4x6 the prints show great detail.

2. I'm using the jar of Folgers shown in the photo. I need to use it up somehow..

3. Thanks for this advice on order. I'll give it a try next time.

4. You added the ascorbic acid? I'll guess that with a handle like Titrisol, you are a chemest?

5. I don't have any other scans other then C41 processed film. Maybe someone could help out and post a 100% crop of tri-x 400?
