Convert to Lab, work on ab channels then back to RGB?


Recommended Posts

What I want to do is apply an unsharp mask in Lab mode on only a and b channels, is this possible?

In photoshop (desktop) I would convert to Lab, select the a and b channels, apply an unsharp mask with a large radius (say 80px) then convert back to RGB

 

edit: figured it out finally, tap document icon with three dots then convert document, then it shows up at the bottom

Hi Athiril,

Welcome to the forums :)

I'm very glad to hear you've since resolved this, many thanks for posting the solution for other users to see!

Please note -

I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible.

Many thanks!
