SHORT DESCRIPTION
  •  Info El Grafo: What you see and describe is a classic example of when the chromatic aberration settings in for example Lightroom are set to the wrong variables. The program can't make the distinction between actual pink/magenta or green/cyan and the CA version of it. The program overcompensates with these angular grey areas and sometimes even other colors. I wonder if this photo would not be better without any CA compensation at all. The author has probably just used the CA settings out of habit or by default and got all these mishaps in the photo. In cases like this it can be better to just go over the photo manually and replace any small CAs with the replace color tool/brush in say Photoshop instead of using the automatic tool. BTW, fun fact: The rectangles around the highlights that you describe as greenish are actually grey. (check it with a drop tool), but since they are surrounded by magenta, your brain will register them as slightly greenish, which is the Complementary color to magenta. Trick of the eyes. :-) --Cart (talk) 14:38, 31 March 2019 (UTC)[reply]
  • @W.carter: That's interesting, thanks for the explanation! My first thought was manual editing with a large brush, but I soon realized that the patterns are way too straight for that. I've never experienced this myself, but it's not difficult to imagine a CA removal tool getting confused by this kind of image. (An yeah, there's a reason I wrote "green-ish looking" instead of just "green" ;-p)--El Grafo (talk) 14:59, 31 March 2019 (UTC)[reply]
