brill64 Posted December 31, 2017 Share #1 Posted December 31, 2017 Advertisement (gone after registration) Yesterday whilst processing my day's files I noticed some odd geometric discoloration around the shirt buttons of two subjects. The subjects were photographed some time apart but each of the files in sequence exhibited the same discoloration. Any thoughts welcome. M10+28Summilux both shot at 1.4.

brill64 Posted December 31, 2017 Author Share #2 Posted December 31, 2017 I thought it was the design of the shirt at first but then : Welcome, dear visitor!

Gobert Posted December 31, 2017 Share #4 Posted December 31, 2017 (edited) Same applies for the collar of the first man.... Which software do you use for processing? Edited December 31, 2017 by Gobert 1 Link to post Share on other sites More sharing options...
LocalHero1953 Posted December 31, 2017 Share #5 Posted December 31, 2017 The images look excessively sharpened. Al the high contrast edges have bright lines along them. Are these raw images straight out of camera with no extra processing? Which processing software are you using? 1 Link to post Share on other sites More sharing options...
Frase Posted December 31, 2017 Share #6 Posted December 31, 2017 you can see it on the edge of the jacket too, as others have said what does the original file look like? 1 Link to post Share on other sites More sharing options...
Mike51 Posted December 31, 2017 Share #7 Posted December 31, 2017 Advertisement (gone after registration) I'm working on very little information, but at a guess I'd say that the culprit could be the use of Lightroom's new range mask tool when using its luminance adjustment. Care is required in its application and, if not, there can be odd colour shifts and bleeds. Having said that, it might be the case that the images were not worked on using Lightroom. If so, I haven't a clue! 1 Link to post Share on other sites More sharing options...
happymac Posted December 31, 2017 Share #8 Posted December 31, 2017 (edited) Did you use demoirizing? If so, reduce it. Edited December 31, 2017 by happymac 1 Link to post Share on other sites More sharing options...
adan Posted December 31, 2017 Share #9 Posted December 31, 2017 Additionally, using the "remove purple or green fringe" lens correction for chromatic aberration can cause color bleeds with red, purple, blue and green edges that are not actually CA. The software is just "not very smart" about knowing what is real CA, and what is just a natural color edge. 1 Link to post Share on other sites More sharing options...
rent Posted January 1, 2018 Share #10 Posted January 1, 2018 Please post/link original RAW if available. It looks to me much processing has been applied. 1 Link to post Share on other sites More sharing options...

rnl Posted January 1, 2018 Share #12 Posted January 1, 2018 same thing happens on a Canon 5dsr...you get a moire pattern due to AA filter associated with the sensor..Lightroom will take it out. some man-made objects tend to exhibit this phenomenon 1 Link to post Share on other sites More sharing options...
TomB_tx Posted January 1, 2018 Share #13 Posted January 1, 2018 If you set the camera to save both jpg and dng you can compare the in-camera jpg to see if this is being caused in post. 1 Link to post Share on other sites More sharing options...

User error here & totally my fault, sorry guys. I went back to the dng file where I'd copied & pasted some settings in ACR CC. The purple colour fringing slider was set way too high. Sliding it backwards totally removed all colour bleed aberration. Thank you all for coming to the rescue. Link to post Share on other sites More sharing options...
