Cross processing is 35mm slide film run through negative chemistry. The channels cross: one colour floods the shadows, its opposite loads the highlights, and the curve goes hard in the middle. Every preset here is that, built on the RGB curves. Cyan Floor is the reference, cyan-blue blacks under warm highlights, for editorial portrait and street.
Warm-up is the gentle end. Violet Base lifts the blacks violet and leaves the top clean. Split Emulsion lifts both ends for a soft crossed haze. Slate Cyan, Ice Highlight, Amber Ceiling and Copper Shift each put one cast in one place. Crossed is the working range: Orange Floor for late daylight skin, Teal Print for coasts, Magenta Toe for portraits, Cold Chemistry for an overcast city, Yellow Crossing for bright daylight, Blue Crush for a yellowed print with cold blacks.
All the way is loud. Rust Channel crushes the green mid under a red print. Green Bloom is the lab error, green midtones over magenta blacks. Lime Print goes acid for street and skate. Warm Reversal reverses the toe and shoulder on skin and cloth. Reversal Bath is the loudest recipe in the set, both warm channels driven against a crushed blue.
Apply the loud one first. Dial it back only if you have to.
