Cross process filter for wild film color

Cross processing is what happens when film goes through the wrong chemistry on purpose. Colors shift in strange directions, contrast jumps and the result looks bold and unpredictable. This preset gives your photos that experimental feel, with blue-cyan shadows, yellow-green midtones and warm highlights.

Where cross processing comes from

Cross processing usually means developing slide film in the chemicals meant for color negative film, or the other way around. The mismatch produces strong color casts, high contrast and saturated tones.

It became popular in fashion and music photography in the 1990s and later with the lomography movement, where unpredictable results were part of the fun.

Photographers never quite knew what they'd get back from the lab.

What this preset does to your photo

Each color channel moves differently. Blue is lifted in the shadows and cut in the midtones, green is raised in the shadows and midtones, and red is raised in the midtones and highlights. The result is cool shadows, yellow-green midtones and warm highlights.

Contrast and saturation both rise strongly. Light grain and a moderate vignette finish it.

Because each channel changes in a different direction, the same preset can look quite different on two photos. A blue shirt, a pale wall and a sunny face will each shift their own way, which is part of the experimental charm.

How to get the best result

Bold, colorful scenes suit this look. Outfits, bright walls and plants all shift in interesting ways. Skin can turn yellow or green, so treat it as a creative effect.

The Film Strip frame and Grid layout make the strange color feel deliberate. Try the 1:1 export for album-cover-style images.

If a result feels too wild, open it in the editor and lower the intensity. Even at half strength the shifted color is obvious, but skin looks closer to natural.

Tips

  • Use bright, saturated colors in the scene.
  • Expect unusual skin tones. That's the point.
  • Outdoor daylight gives the strongest shifts.
  • Pair it with bold poses.

Questions

Why does skin look yellow-green?

The preset boosts green and cuts blue in the midtones, where skin sits. That color shift is typical of cross-processed film.

Is the effect random like real cross processing?

No. The same settings are applied every time, so every frame in your strip shifts the same way and the set looks consistent.

Is it good for portraits?

It's better for fun, creative portraits than flattering ones. For natural skin, use Portra 400.
