Early emulsions were sensitive to blue and blind to red. A sky came out white, a red dress came out black, and a face, which is mostly red, came out heavy and freckled. Every entry here reproduces that inversion first, red and orange luminance taken down, blue and aqua taken up, then fits a curve to the plate.
The register is ruled in three parts. Faces push the red suppression hardest, from the reference Ortho Plate to Dark Lip and Heavy Skin, where clarity is raised so blemishes read as they did on a studio plate. Skies lift blue toward paper: Chalk Sky for a blank overexposed top, Collodion Sky over a firmer curve for landscape, Cyan Bright where water and glazing should lift more than the sky does. Plates hold the emulsion itself: Glass Negative with its coarse grain, Slow Plate at the lowest contrast, Plate Camera with nothing but the inversion.
Apply one, then read the file. Each preset sets the colour mixer, the curve and the grain and leaves every slider in reach, so the plate is yours to expose again.
