Developer

After twenty years with Lightroom, I had opinions about how a RAW editor should work. So I built one.

Photo Developer
The story

Revolutionary tools become infrastructure.
Infrastructure becomes dependency.

Lightroom's catalog was its genius — and eventually its trap. Twenty years of ratings, keywords, develop history, collections. All inside one database. Stop paying the subscription, and your creative decisions are still there, visible, locked behind glass.

The thought that finally stuck was simple: XMP sidecar files already exist for my RAW files. They should exist for everything. Every rating, every keyword, every develop setting — a small text file sitting next to the image, readable by any tool. The database becomes what it always should have been: a fast index. Delete it, rebuild from files. No data lost. No lock-in.

Your photos, your metadata, your creative decisions — stored in open formats, on your own disk, readable by any tool that understands XMP.

That's not a hot take or a rage-quit. It's more like selling a house you've outgrown.

From RAW to remarkable

Three promises

01

Honest controls

Every slider does exactly one thing. Move Highlights to −40 and you get a predictable tone curve compression with film-like rolloff. Same input, same output, every time. No hidden AI fighting your adjustments.

02

Files are truth

Settings live in XMP sidecars — open, portable, readable by any tool that speaks XMP. Delete the app and your creative decisions still exist as plain text next to your images.

03

The machine assists; you decide

AI-powered masks and auto features set visible sliders to concrete values. You can see what it did, agree or disagree, and adjust from there. Smart Develop reads the scene — it doesn't override the photographer.

Twenty shaders, one pipeline, zero mystery

Every RAW developer has a pipeline — a fixed sequence of stages the image flows through. Photo Developer's has 25 stages, ordered by philosophy: broad before specific, corrective before creative. Each stage runs on a custom Metal shader, purpose-built for exactly one job. The result is a processing chain where nothing is hidden and nothing fights your adjustments.

Move a slider, and the image responds before your finger lifts. That's GPU proxy rendering — instant feedback at editing resolution, full resolution at export. The delay between moving a slider and seeing the result is what breaks creative flow. Eliminate the delay and you stop thinking about the tool. You start thinking about the photograph.

The inspector has 13 panels with solo mode, so you see what you need and nothing else. Snapshots let you branch your edit without duplicating files. Thirty levels of undo mean you can explore fearlessly.

No account required. No cloud. No tracking or telemetry. No subscription verification. Just the app, working, on your machine, with your files.

Smart Masks

One tap to isolate a person or subject — Apple Vision does the heavy lifting. Select by luminosity for precision tonal control, or use color range with eyedropper. Paint with the brush for freehand masking. Add selective blur to any mask for portrait work.

"The kill list is longer than the feature list. I think that says something good about the app."
