In a basic editing challenge, are you allowed to sharpen in ways other than in full RGB?
Can you sharpen in a single channel- ie Lightness only (LAB) or green only (RGB) -
or does this conflict with the whole image rule?

I think it is allowed - You are sharpening the (LAB) or gree etc in the whole image and not just a section of the image.

That is my opinion.

Restricting the application of sharpening (or anything else) by tone or color has always been allowed -- it only becomes a problem when the restriction is based on the location of the pixels.

As long as no selection, mask or pixel layer is created it should be ok.

To confirm what's already been posted, yes, you can do this as long as the sharpening is applied uniformly to the entire image on that channel.

Hi Kirbic,

I've recently started using Smart Sharpen as opposed to USM. It allows more control over sharpening by independantly adjusting the fade amount in highlights or shadows. Is this still considered legal for basic ?

cheers,

Smart Sharpen is legal for Basic.

That sounds similar to my question (in a thread a few months back) about using the 'blend if...' option on adjustment layers. I received a few unofficial opinions that it would not be legal.
