Shotwell
Shotwell supports JPEG, PNG, TIFF, BMP, GIF, WebP and RAW photo files. Shotwell's RAW format support is currently limited. When you view a RAW photo, you are actually viewing a JPEG derived from the RAW photo, not the RAW image itself. Additionally, the RAW editing pipeline is not fully 16-bit - you can only export edited photos as 8-bit files. Most supported formats can be used for export (JPEG, PNG, TIFF, BMP). The Basic Information pane appears at the bottom of the sidebar, and displays a brief summary of the photos you've selected. If no photos are selected, it displays a summary of the entire collection. You can toggle the display of this pane using the information command. The map pane appears at the bottom of the sidebar as part of the basic Information pane, and displays an overview map the photos you've selected. If no photos are selected, it displays an overview of the entire collection.
