I don’t know why I’ve overlooked the Amount slider in Lightroom’s masking for so long. It’s a real time saver and the best option to refine a look or masking preset you’ve applied to your image.

In the photo below, I have a targeted adjustment to the rocks on the horizon toward the left side of the frame. I cut the haze and added a bit of clarity and texture. My initial look was too strong… I wanted a bit of the haze to keep depth in the scene. Rather than fiddle with the individual sliders, I used the Amount slider for the entire effect. It is a major time saver!
