I am trying to use masks to edit a photo, and I happen to need to mask overlapping regions. So, the first thing I did was in the desired region I wanted to try to make a sunspot glare in the photo (a small circular shape) less noticeable so I created a new layer and created a mask and adjusted the white balance to blue so that it was less noticeable. Then, I wanted to make the entire background of the photo (distance mountains) clearer by applying a Clarity live filter layer. So I created a new layer and masked the background - But the problem is, the sunspot from the last layer is part of the background. And I cannot figure out how to make it so that the image shows the effects of both mask layers at the same time - I have to choose one to be on top of the other and therefore override the layer below. I am sure there is an easy way that I am just missing but I am new to photo editing - I am teaching myself with Affinity but have never used Lightroom or Photoshop.
