Develop Snapshots allow you to save your adjustments at any point during your development workflow. As you make adjustments, you can take a snapshot at any time to save your work up to that point. You may then continue to edit as desired, but can return to the version in your snapshot whenever you like. Unlike presets, snapshots save directly to your image, allowing you to re-enter Develop mode and switch between them, continue editing them, and apply them.
To Take a Snapshot:
Images with snapshots display the Snapshot icon in Manage mode.
You can view your image with any of the snapshots saved to that image in View mode. This viewing is commitment-free, much like the Auto Lens.
To View Your Image with a Snapshot:
The Snapshot button will only be visible when viewing images with Develop Snapshots you have created in Develop mode.
If while viewing your snapshot, you want to return to the saved version of your image without leaving Develop mode, click the Adjust Develop Settings button and choose Apply Last Used from the menu.
