I often see photographers using the Painter tool in Lightroom to apply star ratings. Don’t forget, there is a whole list of different items that can be applied – including Keywords, Label, Flag, Rating, Metadata, Settings (Presets), Rotation and Target Collection!

Oh thank you so much for that tip! I actually never noticed it was for anything else than keywording!!!
A very under appreciated and overlooked tool!
I cannot find my painter tool at all. I think it had to be to grid view but not. Have you any idea why?
in the grid view, try tapping the “T” key to show your tool bar.
