Rollei Crossbird roll film 127

That depends on the format your camera supports:

35mm (small format) – used in most analog SLRs, rangefinder, and compact cameras

120 roll film (medium format) – for many classic medium format cameras

Sheet film (e.g. 4×5") – for large format cameras, typically in professional use

You’ll find Rollei films in all three formats in our range.

The required film type is usually indicated on the camera body or in the manual.

The ISO number indicates how sensitive a film is to light – and it affects both exposure and image aesthetics:

ISO 25–100 → fine grain, ideal for bright conditions and detail-rich subjects

ISO 200–400 → more flexible in changing light, with slightly more contrast and visible grain

Tip: The lower the ISO, the more precise your exposure needs to be – but you'll get finer tonal values. Higher ISO films are more forgiving and great for spontaneous shots or shooting on the go.

Unexposed film should be stored in a cool, dry, and dark place – ideally in the refrigerator at 5–10 °C (41–50 °F).

Be sure to let the film reach room temperature before use to avoid condensation.

Tip: When stored properly, the indicated expiration date can often be exceeded – especially with black-and-white films. What matters most is a stable environment, ideally in the original packaging or in light-tight containers.

These terms describe which parts of the light spectrum a black-and-white film is sensitive to:

Panchromatic: sensitive to the entire visible spectrum (including red) → produces natural tonal values and is suitable for all kinds of subjects – the standard type for most black-and-white films.

Orthochromatic: not sensitive to red light → increases contrast and renders red tones very dark – ideal for technical, graphic, or experimental work.

Tip: Most modern black-and-white films are panchromatic. If you're unsure, panchromatic is almost always the safe choice.

Yes, many Rollei films can be pushed or pulled very effectively – ideal when working in changing light or when you want to creatively shape contrast and grain.

Examples:

– Rollei RPX 400 can be reliably pushed to ISO 800 or even 1600 – with increased contrast and slightly coarser grain.

– Rollei Retro 400S also responds well to push processing – perfect for high-contrast subjects or low-light situations.

– Rollei Superpan 200 can not only be pushed, but also combined with infrared filters – opening up additional creative possibilities.

– For especially fine-grain results, you can pull Rollei RPX 100 to ISO 50 – resulting in softer tonal values and maximum detail.
