Lab-editing in a rgb-document

Question

Dear community,I'm looking for a way to edit my pictures using the lab color method without changing the document color type. Espeacially for processing my negative slides which I scan as positives to have the lowest possible amount of intervention by the scanner software, I get decent results without extraordinary efforts, by using lab. (In rgb it takes me much more time and the results aren't as lovely.) Unfortunately I need the rgb procedure for further workflow steps. So I wanted to know, if it's possible to edit just some layers or a group of layers in lab, without changing the whole document color type. I know that smart objects do a decent job for such requests, but smart objects do also slow down my workflow and generate a too high amount of data. So does anybody know a good solution for that issue?Thank you and best regards!André

Convert the layer to a smart object. Open the smart object and convert the source file to Lab.

The main encapsulating document remains RGB.

You can create an action to automate some of this instead of having to right-click each layer.

Although already marked Correct, I thought you would like to see this image. The software is Affinity. Free trial version and $50 for the program. Note that while in RGB, the work is being in edited in Lab. To quote the friend who sent this along to me:

"IMHO would consider Affinity a good personal retouching program, not for commercial use but definitely worth the money."

(I think my pal @Trevor_Dennis would get a kick out of seeing this.)
