Rollei Low-Speed And High-Speed Film Developers

The following development times are approximate and intended only as guidelines for individual optimization. They hold for a gamma of 0.65 that is considered appropriate for diffused-light enlargers. In view of variations in individual processing technique, the values should be optimized to suit your own personal requirements.


Due to the unique structure of ROLLEI R³, the developer has a strong effect on film speed, grain and acutance. Proper selection of developer and development time allows control of effective film speed over a previously unknown wide range. ROLLEI R³ is particularly well-suited for low-light photography.


With proper processing, the effective speed of the material can be pushed up to ISO 6400/39° and more. This will inevitably result in coarser grain. The diagram at the bottom illustrates the development times for ROLLEI R³ HIGH SPEED DEVELOPER in graphical form and allows the derivation of intermediate values.


The following developers are highly recommended:

Desired effect Developer
Finest grain and optimum tonal rendering ROLLEI R³ LOW SPEED
Highest film speed
optimum sharpness
ROLLEI R³ HIGH SPEED
Standard for good image quality,
and normal speed
Any commercial fine-grain compensating developer

This is where the special features of ROLLEI R³ come in.

By proper choice of the developer, the user has unprecedented control over the result.


Experience has shown that photographers' first trials of Rollei R³* frequently were unsatisfactory.This is why we would like to provide some basic information directed at both photographers and darkroom technicians: The new ROLLEI R³ is a multilayer film. It therefore calls for comparatively strong exposure if it is to be processed in a professional laboratory instead of by the photographer.In "home" processing, prewashing is essential. ROLLEI R³ will give unsatisfactory results if development was too short in relation to exposure.


The following should therefore be noted: Too short a development will give rise to very coarse grain and very thin negatives - in short, an unsatisfactory result. If development was - within certain limits - too long, however, no photochemical drawbacks will be encountered, except perhaps for steeper gradation and, as a result, minimization of the extremely rich tonal rendering.

Temperature and processing time


To obtain consistent results, it is generally advisable to run all processes at the same temperature, usually 20°C. Should it become necessary to use type D76 or ROLLEI R³ HIGH SPEED developer at a different temperature, use the correction values below, unless other data are available.
