That they tend to use the source profile for gamma… So if I want to make room-light adjustment changes to the gamma curve used by color managed applications, I need to recalculate a new gamma curve in the gamut mapping options to create a gamma curve that it can use. OK, the more I study this, the more I’m beginning to see what’s going on… So, you’re saying that in color managed applications (applications which use the monitor’s profile) Won’t use the gamma curve created in the normal way. This reply was modified 6 years ago by Steve Smith. One more set of instructions and I’ll leave you alone, I promise! Do I need to start over and do two more a calibration\profile combos from scratch for both?ĭo I need to change that setting to ‘normal monitor’ for one, and to ‘bright monitor’ for the other? … In other words, how would your instructions differ now that I will be starting from scratch this time. I want to take two more room light measurements using Displa圜AL again. icc files (one for mid-bright room and another for very -bright room). I’m still learning and your last instructions to me were waaaaay over my head… But still I got the result I was looking for! … I am truly grateful.Īs you know, I want to make two more of these magic. I really have no idea what I just did, lol. #Ambient light adjustment trialSeriously, I’ve been doing soo much trial and error that I am exhausted! Thank you… You explained it very well! … Images are now being presented with ‘true’ blacks, FINALLY!! …Wow! so beautiful I can hardly believe what I’m seeing. OK, so I followed your instructions above exactly. Yes, but in color managed applications normally the source profile determines the reproduced tone curve, so that overrides the calibration. I was under the impression the the ambient light tool effected the calibration globally and so would alter the appearance of everything passing through thr video card gamma table. in Photoshop, do a custom soft proof with the simulation profile set to your newly created display profile and rendering intent set to perceptual). Note that you need to use perceptual intent in your applications to get the desired effect (e.g. Then, select “Create profile from measurement data…” in the options menu, select your existing profile, and save to a new name. monitor in darkened/typical/bright environment). Enable gamut mapping for perceptual intent and set it to “luminance matched appearance”, source viewing conditions to “monitor in typical work environment”, and alter destination viewing condition according to your ambient light (i.e. Enable advanced options in the “Options” menu, then on the profiling tab, open gamut mapping options (the “cog” icon). In that case, all you need to do is re-generate the profile (no new measurements required) with different settings. Could you please tell me what to do differently then as my main concern is in color-managed applications
