RAW viewer is a desktop app which allows you to quickly cull your photos. You can view, rate, manage, and delete all your RAW photos straight out of camera without requiring conversion or importing, allowing you to get to editing your best photos as fast as possible. This application focuses on ease of use and speed, removing all the lag your culling workflow.
All ratings are saved directly to the RAW file, so when you are done culling, you can import the remaining photos into Lightroom (or any other software) and all the ratings will show up.
Maybe you are under the impression that viewing RAW photos in your favorite program is already fast? Or maybe you've been told that RAW photos are really hard to work with and slow is just the nature of RAW photos? Well, RAW viewer is here to tell you that all of that is a lie and culling your photos can be fast!
You can get the latest Windows and MacOS versions here: https://github.com/catdad/raw-viewer/releases/latest
This is a self-contained portable app. Just unzip it and run Raw Viewer.exe
If you no longer wish to use this app, you can just delete the folder where you unzipped it -- but don't worry, all your photos as well as their ratings will stay right where you left them.
While a MacOS package is available, I do not currently have a Mac so I was not able to fully test the package (though the build system does run tests on a Mac). If you are able to test the app and improve the installation and uninstallation instructions here, please open a new issue or submit a pull request. All help is appreciated!
What should work is simply unzipping the package anywhere and running Raw Viewer.app.
Linux support is not quite there yet. If you would like to help, please see this issue.
