# AI use cases for Rembrandt (thesnarkitecht/rembrandt) Repo: [thesnarkitecht/rembrandt](https://github.com/thesnarkitecht/rembrandt) | Use cases: 5 | Page: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/ Rembrandt is a free, open-source photo editor for macOS, Windows and Linux that develops RAW files, manages a photo library and runs AI features on your own computer. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Self-host a photo editor for your home network: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/self-host-photo-editor-for-home-network/ - Edit RAW photos in a free desktop app: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/edit-raw-photos-free-desktop-app/ - Move a Lightroom Classic catalog into Rembrandt: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/move-lightroom-catalog-to-rembrandt/ - Pick the best frames and match exposure across a shoot: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/clean-up-and-match-a-photo-shoot/ - Find photos by describing them, on your own computer: https://dedupedai.com/use-cases/thesnarkitecht-rembrandt/find-photos-by-description-on-device/ ## How to self-host a photo editor for your home network with Rembrandt Repo: [thesnarkitecht/rembrandt](https://github.com/thesnarkitecht/rembrandt) | Difficulty: Intermediate | Time: 30 minutes | Basis: From the README Serve your photo folder from one computer and edit it in any browser on your network. **Who it is for:** A person with a Linux or macOS computer holding a large photo archive who wants to edit it from a laptop, tablet or other device at home. **The problem:** Photos sit on one machine, and editing them from other devices means copying files or paying for a cloud service. **The outcome:** Your photos are edited in a browser through a private link served from the computer that holds them, with edits saved as XMP next to each photo. ### Steps 1. Open a terminal on the Linux or macOS computer that holds your photos. 2. Run `curl -fsSL https://raw.githubusercontent.com/thesnarkitecht/rembrandt/main/install.sh | bash -s -- --server` 3. When asked, choose the photo folder to use. The installer starts the server at login and prints a private link. 4. Open the private link in a browser on the same computer, then run the same command with `--lan` added if you want other devices on your network to reach it. 5. Make an edit, then check that an XMP file appeared next to the photo and that the original photo is unchanged. ### Prompt to paste into your agent ```text Using the repo thesnarkitecht/rembrandt, run the self-host install on with the --server option and report the private link it prints. Verify that the photo folder you chose still contains only its original photos and that any edit creates an XMP file beside the photo. ``` ### Caveat The self-host server runs on Linux and macOS only, according to the README. Risk, remote script: The install command pipes a script from GitHub straight into bash, so read install.sh first if you want to check what it does. Risk, credentials: The private link gives access to your photo library, so do not share it, and use --lan only on a network you trust. Disclaimer: Third-party repos we don't own or vouch for.

Download the installer for your system from the Download table: the macOS .dmg for Apple silicon or Intel, the Windows setup .exe for x64 or ARM, or run the Linux command. 2. On Linux, run `curl -fsSL https://raw.githubusercontent.com/thesnarkitecht/rembrandt/main/install.sh | bash` 3. Open the app. If macOS or Windows blocks it because builds are not yet code-signed, use Open Anyway on macOS or More info then Run anyway on Windows. 4. Import a folder of RAW photos, then adjust tone, colour and masks. Edits are non-destructive. 5. Export a finished photo to JPEG, PNG, WebP or TIFF and check the exported file opens with your camera details intact. ### Prompt to paste into your agent ```text Using the repo thesnarkitecht/rembrandt, download the installer for from the project's Releases page and confirm the file's SHA-256 matches the published checksum. Report the file name and whether the checksum matched. ``` ### Caveat Builds are not code-signed yet, so your operating system will ask you to confirm the first launch.

Install Rembrandt for your system from the Releases page or the Download table. 2. Open Rembrandt and choose the Lightroom Classic import option under Bring your photos. 3. Point the import at your Lightroom Classic catalog and let it run. 4. Open the import report and note any items the README says cannot come over. 5. Open a few migrated photos and compare their edits with Lightroom to confirm they look right. ### Prompt to paste into your agent ```text Using the repo thesnarkitecht/rembrandt, run a Lightroom Classic catalog import into Rembrandt for the catalog at . Report the count of imported edits, keywords and collections, and list every item in the import report that did not come over. ``` ### Caveat The README lists Print, Book, Slideshow, Web and Map modules, face recognition and Adobe's camera profiles as not here yet, so expect some Lightroom work to stay behind.

Open the folder of the shoot in Rembrandt's library. 2. Select the shoot and run Pick the best. Your own flags are kept and one Undo reverts the whole action. 3. Review the picks in Compare (C), which shows 2 to 4 frames side by side with zoom and pan linked. 4. Select the shoot again, choose a hero frame, and run Make these consistent so exposure and white balance match the hero. 5. Check a few matched frames against the hero to confirm the results look right. ### Prompt to paste into your agent ```text Using the repo thesnarkitecht/rembrandt, run Pick the best on the shoot at and then Make these consistent using as the hero. Report how many frames were picked and rejected, and check that your own flags were kept. ``` ### Caveat The README describes the picks as the sharpest frame with open eyes in each burst, so review them before final export.

Open Rembrandt and go to Preferences. 2. Turn on Smart search. The CLIP model (155 MB) downloads once. 3. Wait for the library to be indexed, then type a description into the search box. 4. Open a result and confirm it matches the description. 5. Use Find similar on a good result to find related photos. ### Prompt to paste into your agent ```text Using the repo thesnarkitecht/rembrandt, turn on Smart search in Preferences and search the library at for . Report the number of matching photos and confirm that no photo or search text was sent off the computer. ``` ### Caveat The CLIP model is a 155 MB download, and the README says it is fetched once when you turn Smart search on.
