Having a large working colour space has its advantages
- Image data of RAW files can be preserved: Putting smaller gamut image data into a larger gamut working colour space requires no colour transformations and therefore causes no colours to be changed.
- Reduced risk of clipping colours in customising because of ample “wiggle room”
- BUT we need to tread carefully in order to prevent visible posterisation
→ work with >8bits/colour as long as possible
Using a smaller gamut working colour space has its drawbacks
- Fitting a larger gamut image into a smaller gamut working colour space either needs trimming off or compression of colours. Through rendering intent, we define if colours will be cut or compressed.
- BUT a smaller standardised WCS helps to guess how colours will look for someone not using colour management…although we can never be sure.
The main takeways for me in relation to PhotoLab are the following
- Describe the working colour space (WCS) that is used by default → Details
- Let the user decide if the default or any other WCS should be used…
if there is more than one (the default) WCS. - Let the user decide which transformation should be used…
this is where rendering Intent comes to play.
