Safelight

The name comes from the darkroom: the dim red lamp you can work under without fogging the paper. We wanted that feeling. A quiet room, your photos, nothing uploading anywhere. Safelight runs on the computer in front of you and never stores your photos. The only thing it saves is the presets, as small files you can open and read.

The editing is familiar on purpose. Exposure, white balance, curves, a colour mixer, colour grading, grain, crop. It all runs on the graphics card, so dragging a slider on a big file feels instant. Export uses the same code, so the file you save is the picture you were looking at.

The learning is the interesting part, and there is no AI model in it. Give Safelight a reference photo and it measures the tones, the colour cast, the saturation and the split between shadows and highlights. Then it nudges its own sliders until your picture matches. Give it a before and after and it fits the sliders pixel by pixel. The answer is a preset you can read line by line rather than a black box.

Then we added a compare grid, because nobody chooses a grade by staring at one version. The original sits in the middle with variants around it, each one editable on its own. Drag them around, keep the winner, export the lot as a contact sheet.

It is a prototype. RAW files, LUTs and Lightroom import are on the list, and we are still arguing about how highlights should roll off. While the app catches up, our first preset volume is coming for Lightroom and Capture One. We graded it from the studio’s own photographs.
