[Leica] IMG: this is VERY strange (OT)

[Adam Bridge]

Thanks for sharing that, Jim.

I don’t think I should see any artifacts at all. I was using the procedure that Adorama posts on sensor cleaning:

The addition of the find edges filter was my choice. I was very surprised to see the resultant pattern. Seeing something unexpected is neat - but a bit disconcerting.

Going to try this on my A7Rii next.

I then increased the sharpness with Focus Magic.  As you can see, I have one large spot near the center and two smaller ones in the top right, all of which I was surprised to see.
