Photochemical technique of deliberately processing film in chemistry intended for a different film type – originally E-6 slides in C-41 or vice versa, creating distinctive color shifts, increased contrast, and saturated looks now often emulated digitally.
What is Cross Processing?
Cross Processing (Xpro) is a developing technique where film stock is intentionally processed in chemicals meant for a different film type. The result is characteristic color shifts, extreme contrast, and a distinctive look.
Classic Combinations
| Combination | Result |
|---|---|
| E-6 in C-41 | Slide film in Negative chemistry |
| C-41 in E-6 | Negative film in Slide chemistry |
| Motion Picture Film | Rare, as it's riskier |
Characteristics
| Aspect | Effect |
|---|---|
| Colors | Shifted, intense |
| Contrast | Greatly increased |
| Shadows | Often colored |
| Highlights | Can be blown out |

Today
Cross Processing as a chemical process has become rare, but the look lives on digitally. The characteristic color shifts and high contrast are emulated in color grading – with full control over a look that was once a creative experiment.
