Link to macOS Automator Script to create custom Finder icons for RAW images

[sloan.d]

Using Autamator, I've created a script to extract a thumbnail and use it as a custom Finder icon in macOS. I recently tested it to make sure that the script still works with the latest Sequoia version (15.1) of macOS.

Here is the set RAW preview Google Drive Link.

If interested have a look at the README inside the zip archive. Also note that the extension of the image files should be in uppercase (I noticed that RAW files with lowercase extensions are ignored which could actually be useful for testing or in some other situations). set RAW preview can also be installed as a Finder extension.

One advantage of this approach is that the script should work with any RAW format supported by Adobe DNG Converter (see Camera Raw supported cameras for formats supported by the latest version) whether or not macOS itself has built-in support for that format. In addition to using DNG Converter, the script makes use of Exiftool to extract the image previews.
