Response to Adding Amidol to PMK Pyro

Try this first with film that is NOT IMPORTANT. I do NOT recommend the use of Amidol with PMK. 1. The speed increase is hardly significant, about 1/3 stop in real speed increase 2. It changes significantly the color of the stain. The very useful green stain becomes a brownish to purple-ish stain that lacks the advantages of the green stain with VC paper. Also, I've heard that the pre-mixed PMK is sometimes not correctly mixed. Photographers' Formulary DRY PMK kits are excellent. Better is to mix from stock chemistry. Dial-O- Gram scales are quite cheap at pawn shops. If you don't already have it, get 'The Book of Pyro' and make sure to follow the safety precautions (which are quite simple.)
