Edit your photos,
find a look

Edit your photos with controls you are used to. Brightness and density work the negative, shadows and highlights work the two ends of the scale, and spot colour moves one colour and leaves the rest alone. You see every change on the photo as you make it.

Pick a simulation preset and your photo takes on that film's colour, from muted portrait stocks to saturated ones. Each one is built from the real film's published curves, and every pixel goes the way it goes in a darkroom: exposed onto the negative, then printed onto the paper.

The curves are measured profiles by Andrea Volpato, from the open spektrafilm project.

The curve runs from the shadows on the left to the highlights on the right. Click it to add a point and drag: up makes those tones lighter, down makes them darker. It is drawn on the photograph's histogram, with every other edit already in it.

With no channel picked, the curve moves all three. Pick R, G or B over the plot and it moves that one alone. Blacks and Whites follow the same pick.

A photo looks the same everywhere it appears: on screen, in the book and in the PDF you print. Edits never touch the original file. Copy one photograph's whole look with ⌥⌘C and paste it onto others with ⌥⌘V.
