What does the layer thumbnail size signify?
Hello,
I see I have two different layer thumbnail sizes that I have not noticed before, see attached photo.
Questions:
1) What is the significance of this?
2) Where does Adobe have this information for users to readilly access? I did a search and all I could find was how to set the size. (This is a common occurance for me, not being able to find answers.)
3) Does Adobe have a comprehensive on-line manual for users to reference?
If so, where?
If not, why not?
Thank you for your help!
