I've bought myself a beautiful HP Envy notebook with a 4k display. I wanted a 4k display, because the colour space on such a display comes close to Adobe RGB, and is much better than normal HD displays. Normally only ridiculous powerful and expensive gaming notebooks have such a display, but this is a normal notebook. I just had to import it from the US, since HP Europe doesn't sell them (sigh).

I also bought the X-Rite i! Studio to calibrate the display, the printer, and the scanner.

I first calibrated the display. The calibration settings want the brightness set to 120 cd/m², and that was far less than what it was set to. So I wondered why. It turns out that if you set the display too bright, you may see details that will disappear if you print a photo. After I did some more research, I found that the sRGB profile specifies a brightness setting of 80 cd/m², and the Adobe RGB profile a setting of 160 cd/m². The setting of 120 cd/m² is exactly in the middle of these settings. I usually use the ROMM RGB profile, and that one requires a setting of 142 cd/m², so I used 142 cd/m² (or close to it) for the calibration.

The before and after calibration colours were not very much different, contrary to the situation with a normal HD display. There the differences are dramatic.

My first question is, was I correct in setting the brightness to 142 cd/m² for the calibration ?

The next point is calibrating my camera. It seems it is possible to make a colour profile of my camera, and use that when developing a raw picture. I could not find how to do that in Affinity Photo, but I know it is possible with Adobe products. Can it be done with Affinity Photo?

My last question is about the omission of some modern ICC profiles in the standard set of profiles that is provided with Affinity products. The European Color Initiative has some modern RGB and CMYK profiles on its download page  , like the eciRGB_V2 profile, or some CMYK profiles for coated and uncoated paper. I used one of those profiles for a project. Perhaps these profiles should be included as well in the standard set ?

I would recommend contacting HP directly in regards to the best methods on calibrating your laptop screen as it may already have a optimal profile for the colour range that the panel can support and applying the wrong values can be detrimental to the display output.

If you use your Xrite studio software to generate an ICC profile for your camera and after you install this into your computer you can then assign this profile to your image in Affinity Photo from the Document menu.
