Culling mode allows you to display images side by side for easy comparison.
- In culling mode, you can zoom into images (up to 100%) by holding Ctrl while scrolling with the mouse wheel.
- Pan within zoomed images with click+drag.
- By default, zooming and panning are synchronized between all visible images. If you want to zoom or pan only a specific image, add the Shift modifier to the above actions.
- Use the mouse wheel or arrow keys (←/→) to scroll through your collection.
There are two different culling modes, which define how many images are shown at the same time: “fixed” and “dynamic”. Switch between these while in culling mode by pressing the “<” key.
- fixed mode
- The number of images displayed is always the same, independent of the selection length. This number can be set with a slider on the bottom panel.
In this mode, you will navigate through all selected images. If no selection is set (or if only one image is selected), you will navigate through all images.
The default keyboard shortcut to enter culling in fixed mode is X.
- dynamic mode
- All of the selected images are shown. If no selection is set (or if only one image is selected) the last value from fixed mode is used.
The default keyboard shortcut to enter culling in dynamic mode is Ctrl+X.
Hint: To enhance performance when loading zoomed images, you can enable (preferences > processing > cpu/gpu/memory > enable disk backend for full preview cache). Bear in mind that this can occupy a lot of disk space.
