When I use the brush in Lightroom CC desktop it applies the edits more thickly in the areas where I go over the image repeatedly. (I know that I'm not using the terminology correctly, I don't know what these characteristics are correctly called.) In the attached photo you can see where I was experimenting with the brush. In the lowest section the most intense, densest blue was where I moved the cursor over the image repeatedly while the lighter blue is where I only passed over the image once. Is this how the tool is supposed to work? I would have expected the edits to affect everything covered by that brush to change in a consistent manner. This way I will get enhanced edits along edges that I go back over to clean up.
