Lighthouse is a native Mac RAW browser and developing editor. Point it at a folder of raw files and the whole shoot is on screen at once, on the GPU; open a frame and develop it — exposure and white balance, a free-form tone curve, twenty film looks, OpenFX plugins — then write the settings to an XMP sidecar Adobe can read, or export a 16-bit TIFF.
This is the first public build of a young app. It is signed by RainbowFactory LTD and notarised by Apple, it keeps itself up to date, and it is a beta: work on your own copies of your files and tell us what breaks — Help ▸ Send Feedback… sends the report straight to us.
Lighthouse opens a folder the way the Finder does — and then draws it the way a photo app should. Pinch from the contact sheet down to a single frame without waiting, and pan even huge files without a stutter.
Open a frame and you are in the develop window. Everything you change — exposure, white balance, the curve, the film look — happens live while you drag. Nothing is written into your originals: your edits live in a small settings file next to the photo — the same kind Lightroom and Camera Raw read, so they see exactly what you did and you can walk away from this app whenever you like.
Every camera renders a little differently, so Lighthouse ships two developers: its own, and Apple’s. If a frame looks better one way, open it the other — same window, same controls, your pick per photo.
Everything below is in the build you can download today. It is a first release: expect rough edges, and expect this list to grow.
Pinch to zoom, arrow through frames, drag and drop, select many at once, star what you like — over the whole folder, instantly.
The knobs a photographer actually reaches for — exposure, white balance, contrast, shadows — and they answer while you drag.
Bend the tones with your own hands: lift the shadows, roll off the highlights, give the frame the curve it deserves.
See your colours as well as feel them — the scope sits beside the picture while you grade, like in a colour suite.
That blown-out sky? Often it isn't gone. Lighthouse digs the detail back out of the raw file.
Portra for skin, Velvia for landscapes, Vision3 for that cinema feel — twenty film looks, one click each, grain included.
Already grade with Dehancer or Filmbox? They load right in, controls and all.
Printing the shot? Preview what the paper will do to it before you waste a sheet.
Drag the horizon level and it stays level — one undo step if you change your mind.
The app does the crossing that photographers do every day: from a folder of raw files nobody can see, to a picture somebody can. It browses like a viewer and develops like a darkroom, and it hands the result to whatever comes next — Camera Raw, a print shop, or a 16-bit TIFF in a layered editor.
It shares its engine with the rest of the suite — which is why the grid stays smooth over folders that make other browsers stop and think.
What is in 26.0 →
26.0 is the first build we have published. The chain around it is finished — signed with our Developer ID, notarised by Apple, updating itself through its own appcast — but the app behind it is young: there is no catalogue, no printing dialog, and some formats are better served than others.
Work on copies, keep your originals backed up, and send what goes wrong: Help ▸ Send Feedback… (⇧⌘F) files a report with the log attached, and the floating feedback chat (⌥⌘F) is the fastest way to reach us.
Version 26.0, the first public release. Direct download only — signed, notarised, and it updates itself.
The download is signed by RainbowFactory LTD and notarised by Apple, so it opens straight away, and Check for Updates… in the Lighthouse menu keeps it current. Being a beta, it can lose your develop settings or misread a file: keep your originals safe and tell us what happened — Discord, or Help ▸ Send Feedback… inside the app.
