Confused by Color Profiles


Recommended Posts

Hi,

i am completly confused with color profiles @ this point¬†ūü§Į

  • I shoot in RAW and the color profile on my camera is set to Adobe RGB.
  • I also use a calibrated EIZO Monitor, here i also use the Adobe RGB (Monitor) Profile
  • In 99% my Photos are for Web Use, but I want to keep the larger color space in case I need it for printing someday¬†
  • In the Affinity Photo Settings -> Color i have set both RGB-Profiles to Adobe RGB, i belive this setting is for viewing on the Monitor, or should i choose here the¬† Eizo Color Profile (Adobe RGB) from my Monitor instead?

 

finally i am not sure how i should work and finally export my Pictures for Web Use, should i:

- Export as jpeg with an embeddet sRGB-Profile?
- Export as jpeg without any Color Profile?
- Change the Color Profile of the document in Affinity Photo to sRGB IEC61966-2.1 before exporting and when yes, do i include the same profile in the jpeg export settings?

That setting applies only when your camera is creating JPG images. RAW images have no standard color profile.

The setting in Affinity is for the document's color profile. This is separate from, and has no relationship to, the monitor color profile, which you would set only in your system settings.

For web use, you have to beware that some browsers don't do proper colour management. For the most consistent results you need the rgb data to be usable "as is" without relying on an icc profile.

Non colour managed browsers assume sRGB, so you will need to convert your document to that colour space prior to export. It wouldn't hurt to also embed the sRGB profile at export. When converting the document it's best to work from a copy as it's a destructive process.

Always convert images from Adobe RGB to sRGB before saving for web use. Most monitors and devices cannot show all the colours in the Adobe RGB colour space.

I always checki the final result on an iPad Pro.

Exporting JPG files with the integrated sRBG color profile is far too colorful for me. Without a color profile, the colors have a kind of washed-out look for me, in direct comparison to the original.
I export with a compression rate of 85%

on my cheap old monitor there was no such difference ;-)

From what I understand of iOS, there is no colour management so it's essentially limited to sRGB. If you view a wide gamut (e.g. Adobe RGB) image you'll get muted colours compared to the true representation. An sRGB image should display correctly.

iOS has had native colour management for the last 5 years and almost all recent Apple devices have a display with approximately P3 gamut.

I'm a bit out of date then, I did have a quick look online but couldn't find anything recent and specific.

In general though for web use it's still going to be best with sRGB. Lots of old devices out there, and ones which struggle to even get to the sRGB gamut.

This advise is outdated in 2022 (or since about 2017).

all relevant OS (windows, MacOS, IOS, Android) and web browsers (Edge, Chrome, Safari, Firefox) support color management and DCI-P3 for at least 5 years, as video / HDR has driven this in AV devices for years (DVD, BlueRay, BlueRay ultra (4K), almost every full HD and 4K monitor with HDMI and BlueRay logo.

Of course, some apps are still assuming sRGB today, like MS explorer and photo App, but images are viewed predominantly on mobile devices, either on browser or social media apps. All I tried work with DCI-P3.

It isn't so much the software, either OS or Browser, supporting the DCI-P3 as it is that there is old hardware running a recent OS and using an up to date Browser.

Mac Pro (Late 2013) Mac OS 11.7.1 
Affinity Designer 2.0.0 | Affinity Photo 2.0.0 | Affinity Publisher 2.0.0 | Beta versions as they appear.

I have never mastered color management, period, so I cannot help with that.

The thing I mentioned was the devices themselves physically being unable to hit the full gamut.

Take a look at what a few current low-end laptop screens can reach and it might shock you. Some are less than 70% of sRGB.

If you are talking of low end windows laptops, maybe.But these devices will show wide-gamut images generally correct, only capped to srgb colors. This means only colors outside the srgb range will look slightly different, probably unnoticeable for most viewers. They wont look totally strange, or desaturated or overly saturated in general. If you see a general issue with every image, the color management is mis-configured.
