Being new, I have not used that feature – so I am not much help when others are trying to help me. However, the screen as current usage, has the image being edited in the left half of screen and whatever adjustment that is currently selected in the right part. Currently, I am working with the various selections that may be used for Sharpening and have the screen set to 100 (or above 100 ) and I have NO idea what percent that is currently being displayed.
The other “viewing in full screen” I believe is self explanatory since all settings would NOT be available but the entire screen could be used to view the current progress in any adjustments that have been made.
I failed to mention that even if I knew how to post, the current image is of a Family Photograph (at Christmas time) that I can not post in a Public Forum.
