250swb Posted July 19, 2016 Share #21 Posted July 19, 2016 Advertisement (gone after registration) In System Preferences, in the Systems section, open Accessibility. Under Setting on the left hand side, select Display. Is the Enhance Contrast slider pegged left? if not, move it over. But wouldn't that simply artificially adjust the contrast so the image only looks good on certain monitors, it doesn't actually get rid of the artefacts in the file and it is lack of calibration (and too high contrast) that hid them in the first place? Fine if all your workflow is centred around a single monitor, but send the image to a client, post it on the internet, send it to a printer, and the artefacts will most probably show up again.

Exodies Posted July 19, 2016 Share #22 Posted July 19, 2016 It's not about artefacts in the file - the laptop was squashing the top four bands in the grey scale to white in order to increase contrast in the mid tones. Link to post Share on other sites More sharing options...

So every other computer in the world would need to be as equally screwed up to see the image that the OP thinks they've got, otherwise everybody else using a normal calibrated monitor will see the artefacts caused by the retouching. The 'squashed bands' hide the artefacts, ipso facto they are only hidden on one computer, so the artefacts need removing properly or they will continue to be seen by anybody else on another monitor. Good grief................... Link to post Share on other sites More sharing options...

Good grief................... This is what the thread was about when it started: why are the artefacts hidden only on the computer where the image was edited, and how to make them visible even there. The solution has been mentioned and confirmed, BTW. Link to post Share on other sites More sharing options...
