Characteristics and uses
ROLLEI R³ is a low to high-speed black-and-white negative film of high acutance, based on the use of classical cubic crystals. The film speed actually used
is a function of the type of development.
In conjunction with depth developers, optimum results can be attained above all between ISO 25 and 200.
In conjunction with fine-grain compensating developers, optimum results are possible primarily between ISO 100 and 6.400.
ROLLEI R³ is highly responsive to specific developer properties. As a result, the selection of the developer is decisive for adapting the material to individual
Sensitization goes up to about 710/730 nm, which makes the material SUPER-APOCHROMATIC. Its sensitivity to infrared can be utilized photographically only if a
black filter with a cut-of wavelength of 700 nm is employed.
The emulsion of ROLLEI R³ is made up of three extremely thin layers with silver halides of different size and three different degrees of sensitivity. This
technology leaves a very wide margin for controlling the properties of the material by suitable selection of developers and development time. As a result,
ROLLEI R³ allows the entire spectrum from fine-grain low-speed images (ISO 25/15°) to maximum-speed images (ISO 6400/39°) to be used with considerably
better shadow detail and finer tonal rendering than with films pushed the conventional way.
Another specialty of ROLLEI
R³ is its antihalation layer that is coated directly on the transparent film base. This results in greater sharpness, since reflections are not allowed to
penetrate the film support before being reduced, but are eliminated even before they can enter the base.
ROLLEI R³ is suitable for all kinds of pictorial applications. This applies above all to portraiture, but also to theater and available-light photography.
A new field of application for this type of film is architectural photography. Here, sheet film and very low ISO values are widely used in order to attain extremely
high resolution and fine grain.
The film may be processed in many different B+W developers, with a wide margin of control.
The glass-clear material of the PET support makes the material suitable for use as B+W slide film. A special protective SUPERCOAT results in greater resistance to
aggressive photo chemicals.
The polyester film support guarantees the highest level of archive stability.

In complete darkness
As with all light-sensitive materials, it is recommended not to leave the material exposed to direct sunlight, strong heat (e.g. in a car) or high relative
humidity. The expiry date printed on the material applies to storage at room temperature of 18° - 22°C. If stored at 8°C, the shelf life of the material will be
extended by approx. two years. Material stored at low temperature should be left to adopt the ambient temperature before it is removed from its packing and exposed
to ambient air. If the film is much colder than the ambient air, there is a risk of condensation.
