Hi Steve,

Seeing as there are monitors that have direct ColourSpace intergration (eg SW321C,CG319X) also have the Adobe RGB colourspace, would you consider adding this to ColourSpace?

I know users can add and modify Colourspace's but I wouldn't know where to find the space to add myself. I am also looking at buying one of these monitors and would like the option of Adobe RGB calibration directly through Colourspace.

It's not an urgent priority I know but it would be good if you would consider adding this Colourspace to the program.

Thanks for your time.

Aaron.

As Adobe RGB is not a valid colour space for the Film & TV industry we deliberately have never added it as a preset.

Red: 0.6400, 0.3300
Green: 0.2100, 0.7100
Blue: 0.1500, 0.0600
White: 0.3127, 0.3290

EOTF 2.2
Peak white 160 - 200 nits.

Hi Steve,

Thanks for the reply, Yeah I thought it wasn't a focus for you because you seem to be more film and Tv.

So if I was to go to Rec709 for example and modify the primary's and white with the x and y values you provided then save that as a user modified space would give me the adobe rgb space?

Thanks.

Aaron.

Rec709 is EOTF 2.4, so you would need to change that too.
Or use sRGB as the starting point, as that is EOTF 2.2.
(Ignore those that talk about a compound EOTF/Gamma - that is wrong for any sRGB display calibration.)

Thanks Steve,

I have modified the colourspace with the Adobe RGB primaries and 2.2 EOTF. It is amazing that I as a user can add any Colourspace that I wish, just goes to show how powerful the software really is.

Thanks.

Aaron.
