Is there any way to load these high-res curves automatically?Īnd one more thing: after having used dispcalGUI with administrator rights to install a profile, I get this error when I try to set a default profile in Color Management. Not only the curves look different, but the grey gradients seem to change, too. I have noticed that when a calibration file is loaded at startup or enabled at Color Management settings, the calibration curves don't look as smooth as when a setting is selected by dispcalGUI. Regarding the 2.4 Lux value, yes, my room was dark, but I doubt that my Spyder4 is able to get the correct value at such low levels. Now I'm wondering if everyone calibrates like this or I'm gonna be the only one that looks at darker images in a darkened environment. So it looks like the color managed renderings in Firefox aren't really correct since I haven't specified an ambient light adjustment in the advanced LUT settings. Thank you for the time you took to write such a detailed reply. Regarding the 2.4 Lux value you used for ambient adjustment, that seems quite low unless you view in a completely darkened environment (the reference sRGB viewing conditions assume a dim environment with about 64 Lux, and that is also why the ambient adjustment you used results in a darker look - it corrects for un-colormanaged sRGB material so it doesn't look too bright in your dark viewing environment).

If you want a similar viewing condition adjustment for both un-colormanaged and colormanaged viewing, you probably have to play a bit with the advanced profiling options for LUT profiles (I'm not sure how successful that will be because I only offer some presets, Argyll CMS itself is very flexible in that regard though, and you can specify commandline parameters for colprof via the options menu) If by 'correct' you mean 'matching the colormanaged result using a profile without viewing condition adjustment', then yes. Un-colormanaged sRGB images will only appear of the same gradation as the colormanaged sRGB ones if the sRGB TRC calibration was either done without ambient adjustment, or a LUT profile with a viewing condition adjustment is used that gives the same result as the ambient adjustment.įor this reason, I believe that the ambient light level adjustment doesn't help to get the correct tone curve response in unmanaged software. According to the site, this comparison shows the deviation of the calibration from the correct sRGB colorspace. However, when I visit the page below and test the tagged/untagged sRGB photo set, having set the Firefox color management value to 2, the untagged photo appears to be darker. If you've created a LUT profile with viewing condition adjustment, be aware not all applications actually allow you to set the rendering intent for the display profile (some that do: GIMP, Photoshop in Softproofing mode, Firefox via gfx.color_management.rendering_intent) Because of that, the effect of the calibration ambient adjustment will only be visible for non-colormanaged material The profile negates the effect of the calibration ambient adjustment when the profile is used (regardless if it was created with a viewing condition adjustment or not)

On the profiling side, by creating a LUT profile with a gamut mapping for perceptive and/or saturation rendering intents and setting appropriate viewing conditions (these settings can be accesed via the 'Advanced.' button next to the profile type dropdown), and then using these intents in colormanaged applications.

On the calibration side, by setting an ambient light level adjustment.

Regarding the ambient light adjustment feature, I find it very confusing.īasically there are two ways in dispcalGUI to allow for a viewing condition adjustment:

In a scenario where not all applications make use of ICC profiles (video, gaming.) it is probably safest to calibrate for 2.2 gamma, which is also the default setting in dispcalGUI (note though that some games overwrite or reset the video card gamma table which is used for calibration).

Gamma 2.2 or sRGB are probably the safest bet. I'm not sure if they follow any standard. Which gamma setting is most suitable for gaming? I'm pretty sure game studios calibrate their monitors to some standard. 709 curve is a source encoding, it should be used together with an ambient adjustment and can then be used for (e.g.) video viewing. 709 gamma curve? Should it be used for viewing movies at home? The sRGB curve is quite similar to a gamma 2.2 curve, but it's less steep towards black, and thus should potentially make it easier for the profiler. I thought the sRGB tone curve should be chosen for calibrating PCs for use with color unmanaged software. Many displays have a native response that is relatively close to 2.2. What settings should someone choose for casual, a-bit-of-everything use? For example, surfing the web, watching movies on PC, gaming and sRGB photo viewing?
