Fotospeed DY15 Fotodyes are designed to be used on any photographic emulsion. These true dyes are completely absorbed by the emulsion therefore leaving no surface marking.
The dyes in this kit come in 11 different colors with one reducer . All the dyes can be fully intermixed and /or diluted to produce any color or shade desired on color or black and white prints. The dyes are extremely concentrated so careful handling should be exercised when diluting. It is not very common to use the dye undiluted with the exception being color 35mm title slides.
When using Fotospeed DY15 Fotodyes for the first time, testing the strength of color on scrap prints is recommended. The first test can be three drops of dye to one teaspoon of water. You can then see the effect of stronger color by adding more drops of dye.
