For so inexplicable reason Photoshop decided to return all my preferences to their defaults. I realized that when my photoshop desktop turned to a dark template and I prefer a lighter gray.
Recently I've noticed halos around my RX10 iv images, even though I shut off the sharpening in the Standard jpg setting.
Head bonk: The default for sharpening in CS6 preferences is bicubic automatic which automatically sharpens all resized down images. I returned it to just plain bicubic and I don't see those halos now.
Do you see any in this image resized down from an extra fine jpg sent to my phone via NFC?
