I shoot only RAF files, so I had to go to LRCC to adjust the exposure and convert to jpg in order to go into Photoshop. 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. I think you just got some extreme results from your selections. http://www.gallery.leica-users.org/v/OldNick/20170810-DSCF4019.JPG.html Jim Nichols Tullahoma, TN USA On 8/10/2017 1:49 PM, Adam Bridge wrote: > Okay, I have seen something I can?t explain.
