Colour Space Explained - Input, Working & Output Colour Space Facts You Need to Know.

Colour Space Explained - Input, Working & Output Colour Space Facts You Need to Know.
Today I want to make you aware of Colour Space facts you might not be fully aware of.
Cameras have a colour space, sometimes known as 'capture space'.
Raw Processors have a 'working space', and their outputs have an 'output space'. 'Working' and 'output' spaces you are familiar with would be ProPhotoRGB, Rec2020, AdobeRGB1998 and sRGB.
And your printer has many 'colour spaces', all dictated by the paper and ink combination you choose for your image.
All 'working' and 'output' spaces are synthetic, and are not in any way device specific. Camera and Printer spaces are the opposite, and are totally device specific.
I also look at colour space tone curve gamma, and the differences between linear gamma and non-linear gamma.

Thanks, Andy Very informative video. I love this type of information. By the way, capturable is a real word Looking forward to the next Dt video.

Excellent explanation. I was somewhat gratified (and more than a little amazed!) that I actually had a more-or-less correct understanding of the topic in general. Incomplete to be sure, but more-or-less correct! At least your explanations made sense ... but don't ask me to repeat it tomorrow. 🙂 I use Affinity Photo and it ships with ROMM RGB: ISO 22028-2:2013, which I believe is (basically?) the same as Pro Photo.

[@AndyAstbury]

Hi Len, yes, reference output medium metric is ProPhoto - you can see why they thought of another name!

Well done Andy, very good explanation as on Profiles. I am a Darktable user and again tried Rawtherapee but what a change on quality you get. I compare both apps and I must say it is harder to get the quality in DK. I never worked with input profiles in DarkT now I will but I can not find the ICC versions of DCP profiles. Maybe you can do a show on this topic in the future. For now I will play with RT. Later Andy

Thank you for sharing your expertise. Once I import I follow your ideas on working in ProPhoto color space. I have a Sony A7RM3 and the only color space options I have in camera are sRGB and Adobe RGB. I assume this is for JPG and the RAW files are a broader or wider color space?

[@AndyAstbury]

Nooooo...........the in-camera colour spaces are for when you shoot tiff or jpeg! Raw files have no profile attached, and contain colour information that CAN lie well outside any synthetic working space in your raw editor, hence using ProPhoto 'keeps' the biggest number of captured colour.

[@OleksandrLemberg]

Yes, your assumption is valid. Those in-camera color profiles settings affect the in-camera JPEGs only.
