Prompt

Apply a Cross Processing effect with pronounced cyan-green shadows, warm yellow highlights, and unexpectedly saturated reds. Increase contrast, deepen dark areas, and introduce fine photographic grain with uneven color shifts across the tonal range, creating chemically altered film rather than a uniform tint. Keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Unusual color casts coincide with altered contrast.

Principle

The film is developed using chemicals intended for a different type of film.

Example

Lomography: Slide film with C-411 color shifts.

Try it out

Shift the color channel curves2 differently. Pay particular attention to neutral areas.

Background

The combination of slide film and color negative chemistry was particularly associated with experimental color aesthetics. Often, slide film designed for E-6 is processed in C-41. This results in negatives with sometimes strong, film-dependent color shifts. The reverse combination is also possible, but produces a different character. Digital X-Pro presets transfer a selection of these results without actually performing the chemical reversal.

Distinction

Cross-processing is a chemical process, not a uniform shade of green. Film type, exposure, development, and scanning determine the result. In analog experiments, the lab needs to know in advance which film is to be processed differently.

Aftermath

A supposed mistake can become a consistent stylistic device.

Question

Does the standard X-Pro slide film experiment produce a slide or a negative?

Show possible answer +

A negative: The E-6 slide film is developed using C-41 chemistry.
