Affinity Photo recognised the colour space of Olympus raw image as sRGB (should be Adobe RGB).

Hello, Affinity Photo seems to have some problems on recognising the colour space of .ORF file. On my camera (Olympus em1 mark2), the colour space was set to Adobe RGB. It could be proved in Olympus Workspace. As shown in the screenshot below, the colour space was Adobe RGB indeed.

However, in Affinity Photo, the colour space was recognised as sRGB IEC61966-2.1, instead of Adobe RGB.

Then, I exported the raw image to TIFF in Olympus Workspace. ICC profile was kept as Adobe RGB. And open the .tiff photo with Affinity Photo. This time, the colour space is recognised correctly as Adobe RGB.

So, why does the problem occur? It was caused by a bug, uncompleted support of .ORF file, or it was a normal phenomenon?

(My computer is MacBook Pro Intel, Operation system is 11.1, Version of Affinity Photo is 1.8.6)

Thank You!

Hi,

even it says/reads sRGB there it should be operational an unbounded space, so usually a full-float linear RGB working space, thus with a gamut (color space) similar in wide to ProPhoto (ROMM) which goes much beyond Adobe RGB.

Welcome to the Serif Affinity forums, @Thomas Xu.

RAW images do not have a color space, and are neither sRGB nor Adobe RGB.

When a camera has a setting for that, it is usually used only when the camera is producing JPG output, not RAW output. Your camera's manual will have more information on that.

The above shown Olympus Workspace probably shows/lists only the cam internal made/setup settings there (...things it would also keep as Exif data if an image is captured and processed in cam as a bitmap JPG/TIFF image and for cam internal preview). For the RAW file format the color space (gamut) setup as default inside the cam is meaningless, since the raw data fetched from the sensor isn't associated or limited to any ICC defined color space so far. - Later after a RAW file is processed inside a RAW converter software, that final processed result (the image color data) will be mapped and associated to a specified color space (gamut) here, so screen devices (monitors) can make use of it at all and show up the image then in terms of the specified color space.

As RAW has no colour space attached AP attaches a colour space to image in develop. It should follow AP working colour space set in Preferences.
