Hello Affinity Users Group - I am using Affinity Photo to make a panorama of a mountain scene. I used the brush selection tool to select the sky, at the end of which I used the "Refine" option to improve the details of the boundary between mountain and sky. When I was finished, the boundary between mountain and sky, as delineated by the "marching ants," looked quite good, and at that point I made a mask based on that selection. I was expecting the marching-ant boundary to be perfectly binary, with pure black on one side and pure white on the other. However, when I take a close look at the white-black boundary of the mask, it is not very clean. That is, the white part of the mask near the boundary has a number of gray pixels (within a width of 20-50 pixels or so), and the same is true for the black part of the mask near the boundary. The result is that the mask near the boundary is "leaky." One way to clean this up is to use the brush tool to clean up this "noise," painting white on one side and black on the other. However, my panorama is large, and the white-black boundary has a lot of structure, so a manual repair using the brush tool would be quite tedious and time consuming. Can anyone shed some light as to why I get this leaky boundary, and can you recommend an efficient way of cleaning it up? Thank you.
