Fotospeed FR10 is a silver reducer supplied as a powder. Although traditionally used for B&W negatives, it can also be used for reducing the density of B&W prints or any material where silver is the base. Hypo crystals are supplied in the kit for the refixing of the image after reduction.
For underexposure, we suggest you try selenium toning. With Selenium, you will gain overall density with extremely fine grain. It is better than using Chromium Intensifier but where there is no detail, you will get more density and no more detail.
