Help and contact

Redlamp is made by one person, and I read every report. Here's how to reach me, what makes a report easy to act on, and answers to the questions people ask first.

Report a Bug or Send Feedback

In Redlamp, choose Help › Report a Bug or Send Feedback…, with no GitHub account needed. Reports are public on GitHub, and you see everything a report holds before you send it. Help › Your Reports follows the replies.

GitHub issues

With a GitHub account, search the issues, follow one or open your own on Redlamp's repository.

Discord

Ask a question, share an edit or talk to other photographers using Redlamp on Redlamp's Discord.

Email

For anything you'd rather not post in public, such as a privacy request, write to me at pdcgomes@gmail.com.

What to put in a report

  • What you did, what you expected, and what happened instead.
  • The steps that make it happen, and whether it happens every time.
  • A screenshot, if it shows the problem. Redlamp offers one of its window.
  • The photo's details and the Mac and the Redlamp build, which a report includes unless you switch them off: they tell me the camera, the version of Redlamp, macOS and the Mac.
  • For a photo that looks wrong, what you compared it with, such as the camera's own JPEG or another app.
  • For a crash or a hang, the report Redlamp offers at its next launch, or the one in Help › Your Reports: it includes what happened.

Before you send it

Reports are posted in Redlamp's public issues on GitHub, where anyone can read them. File names become Photo A, Photo B unless you include them, and paths, folder names, location and serial numbers are never included. Add your GitHub username if you'd like to be mentioned and notified of replies; without one, Help › Your Reports lists what you've sent, with a link to each report.

A photo Redlamp can't open shows a button to report it, which fills in what it knows. Reports can't carry raw files: if a problem needs one, I'll ask on the issue.

Questions

What do I need to run Redlamp?
A Mac with Apple Silicon, running macOS 26 or later.
Does Redlamp support my camera?
Redlamp reads raw files with LibRaw, which reads the formats of more than a thousand cameras, and it opens JPEG, HEIC, TIFF and PNG files too. The cameras page lists the cameras Redlamp's tests verify and those photographers have tested. To test yours, choose Help › Test Your Camera…
Where are my edits kept?
Next to each photo, in a sidecar file with the photo's name, such as IMG_1234.ARW.redlamp. Edits are saved as you make them, and Redlamp never changes the original: not when you edit it, and not when you export it. Keep each sidecar with its photo when you move or back up your photos. Your recipes are in ~/Library/Application Support/Redlamp/Recipes.
Does Redlamp upload my photos?
No. Redlamp develops your photos on your Mac, AI masks and Generative Remove included. The privacy policy says what the app does send, and when.
How do I update Redlamp?
Redlamp keeps itself up to date, however you installed it: choose Redlamp › Check for Updates… at any time, and turn automatic checks on or off in Settings › About. Move Redlamp to Applications before you open it, since a copy opened from Downloads or the disk image can't update itself. With Homebrew, brew upgrade --cask redlamp updates it too. A build from source never checks: pull the latest source and build it again.
How do I uninstall Redlamp?

Quit Redlamp and move it from Applications to the Bin, or, if you installed it with Homebrew, run brew uninstall --cask redlamp. Redlamp keeps these on your Mac, which you can delete afterwards; in Finder, choose Go › Go to Folder… and paste a path:

  • ~/Library/Application Support/Redlamp: your recipes and looks, the AI models you've downloaded (which can take several gigabytes; Settings › Models removes them), the reports you've sent and lens profiles.
  • ~/Library/Caches/app.redlamp: thumbnails and other files Redlamp can make again.
  • ~/Library/Caches/Redlamp: What's New, kept for when you're offline.
  • ~/Library/Preferences/app.redlamp.mac.plist: your settings.

brew uninstall --zap --cask redlamp also removes the Application Support folder and your settings. Your edits are in the sidecars next to your photos, and uninstalling leaves them alone: delete them only if you no longer want the edits.

Privacy

What Redlamp and this site send, who receives it, and how to ask for a copy or for it to be deleted, a report included, are in the privacy policy.
