Using FMS > Opening an Existing FMS Image
There are two ways of presenting an FMS in the Darkroom:
Whole FMS as one single image: To do this, in the Image Viewing Workspace, double-click on the FMS image title bar to enter the Darkroom.
Each individual image inside the FMS: To do this, in the Image Viewing Workspace, double-click on an FMS frame that contains an image to enter the Darkroom, then click the left/right button to navigate to the adjacent image within the FMS. The navigation will end when you reach the image with the least frame ID or greatest, depending on the direction.
