Write the first reviewRollei RHC is a highly concentrated black-and-white developer for film and photographic paper, specifically designed for maximum contrast and clear tonal separation. Originally developed for reprographic, technical, and document applications, it is equally suited for creative photographic projects that require strong highlights and deep shadows.
Thanks to its unique chemical formulation, RHC suppresses mid-tones, enhances shadow detail, and creates a striking, graphic visual impact. In film development, it produces hard gradations with maximum contrast and excellent edge sharpness—ideal for technical originals, text documents, line art, and microfilm.
In creative photography, RHC can be used as an expressive stylistic tool—for abstract imagery, graphic reduction, or experimental concepts that intentionally avoid smooth tonal transitions. It is also suitable for high-contrast paper development or for achieving lith-like effects.
