Comments about Kodak Kodak Fixer for paper and film, 1Gallon mix:
I love this product. It has worked well with both film, color and black and white, x-ray film, and paper. has a low odor, unless all the silver halides are removed from the film, and works great even with a high concentrate of stop bath.
