When post processing photos which color space should you work in, sRGB, Adobe RGB, or ProPhoto RGB? I’ve seen a ot of discussion on which one should be used. Some of it just plain wrong.
It’s a common refrain to work in the space that your end target will be in. It goes something along the lines of “You shouldn’t work in color spaces that the target color space doesn’t use.” Or, better yet, it should be within the gamut that your monitor utilizes.
To put it simply, that is completely wrong. You should be doing your post processing in the largest color space available (in this case, ProPhoto RGB), and then convert the end result to the color space required for the intended target.
Rather than rehash why you should do that I’ll refer you to this article. It gives a very high level explanation as to why. You would be wise to read through the comments as well.
If you want to dig deeper, I would recommend going to this site.
Individual workflows can be as varied as there are individuals, but working color spaces need to be the largest color space available.
In a later post I’ll go into my workflow. Not to convince anyone, but to give an idea for those who are new, newish, or just looking for some inspiration.
