Enable RAW Rendering: Select to render RAW previews. This is helpful if you have made changes to the RAW files in other products, such as Adobe Lightroom®.
On Windows and MacOS, Adobe DNG Converter can be used as the RAW rendering program. If you choose to download Adobe DNG Converter, you need to specify where the app is located on your computer.
For macOS, the default installation location is in the user account's Applications folder.
For Windows, the default installation location is C:\Program Files\Adobe\Adobe DNG Converter\.
On macOS, Apple ImageIO can be used for RAW rendering as an alternative to Adobe DNG Converter.
When rendering images: macOS only - Provides three options for when to render RAW images:
- Always render RAW photos
- Only render RAW photos on demand - uses the 'Toggle Render Quality' keyboard shortcut to render RAW photos. By default, this is the Q key.
- Render RAW when embedded preview is small - When a lower resolution embedded JPEG preview is found in RAW images, Photo Mechanic will send those RAW files to the chosen RAW renderer to create a higher or full resolution preview.
Render Cache size: If you have a large drive with available free space, you may increase this number, especially if you use files that are slower to render, such as HIF. Your preferred settings depend on your workflow.
Remove cached files that are older than ___ days old: Select this to specify how often you want to purge old files. If you use a larger cache size, you may want to do this more often to avoid filling your drive.
Empty Now: Clear the cache now. This deletes the render cache and does not delete any photos.
