Is Lab color (L*a*b*) still relevant?

Getting back to the original question: LAB is a tool retouchers can use. Like a mechanic, a good retoucher should have a complete tool set to tackle anything that comes along. Sometimes LAB is not the answer. Sometimes it is.

We receive files from hundreds of sources, some professional, some not. RAW submissions are rare, and often come without the XMP file that saves the Photographers corrections. When we get a RAW file that shifts our focus to Camera RAW and the desired results can be amazingly quick and simple to achieve. But again, RAW file submissions for us are few.

We need to adjust our tool set for every order submitted, as I'm sure is the case for most retouchers. Whether it's LAB, RGB, or CMYK, we chose what works best for the image we're currently working on.

As a side note, we output our scans to LAB, which makes the process simpler and avoids some of the color shift issues we had before making that change.
There's virtually nothing in what you have said that I could agree with. If you had said, "I do this" or "I do that" then I could just accept that your experience is different from mine (and quietly disagree with you). But when you say "We" it implies that you are speaking for the majority of (professional) retouchers.

Personally I've never used Lab. I know how it works, but I just never encountered a situation in which I felt the need to resort to it. I'm not saying that there aren't things you can do uniquely in Lab, but if you are ultimately going to convert your work back into RGB the whole exercise does seem fairly pointless.

I suspect the 'We' was his company or where he works? That's how I read it.
But I'm with you in terms of people who speak for everyone and it's a common occurrence seen around these parts and others. Very annoying.

Ditto on reading "we" as "the company Shoku works at".

We were amused.

.
I don't speak for people I don't know. I only speak for people I know and work with. The "We" in my statement refers to myself, and the two other retouchers I work with everyday.

Not if the results you are trying to achieve are accomplished better in LAB.

Re: Is Lab color (L*a*b*) still relevant?

Once you convert back to RGB no values unique to Lab can be expressed. So the only advantage is that certain operations may be theoretically easier to achieve in Lab. I'm sure that is the case. Lab is different, therefore by definition there must be SOME operations that it can perform more directly. The question is whether they are genuinely useful, or whether converting to Lab, and adopting a different colour 'mindset' to perform an operation and then converting back again, is really just a pain in the neck for most people who spend their entire working lives thinking and working in RGB.

And that's what is up to debate.

@ Shoku

What are your jobs? I suppose you do a lot of restoration work?

Re: Is Lab color (L*a*b*) still relevant?

Our clients come from national and international corporations as well as small local businesses, who use print advertising from catalogs to postcards. which includes clothing, jewelry, automotive, real estate, photography, galleries, museums, universities, sports, food, etc.
Our creative services can build a campaign from the ground up, or take work already designed and enhance it. Some work is extensive, some not. The issues we deal with vary from client to client but in the end it all comes down to how good their product or service appears in print. Some clients visit us in-house to consult with us, others do everything from a distance due to their location.
