About Rollei RLC12

ROLLEI LOW CONTRAST RLC12 developer is a special developer for technical film including Rollei ATP1.1, with very steep gradation. Based on developing time, these films can be used through bending of gradation, for normal photographic purposes. The negatives showing a very fine grain structure, extremely high edge sharpness and an excellent rich toning range.

ROLLEI RLC LOW CONTRAST film developer is more oxygen sensitive than other developers. Therefore, air must be squeezed-out from the open container, as much as possible. Small amounts should be refilled into a small dark glass bottle. Color of the concentrate should not be changed into brown color. Developing times of technical films must be tested and figured for individual taste. The basic time figure is 6 minutes for a middle gradation. Any time extension, increases the usable sensitivity and will increase contrast.
