Title: No RGB channels option under the Tone curve in LR 4 beta ?
Post by: Remko on January 17, 2012, 02:53:10 pm

I recently downloaded LR 4 beta onto my Mac. Made a copy of a couple of photos and imported these into the LR 4 catalog.

For some reason I do not get the RGB channels in the Tone curve. I mean,  the RGB channels should be visible under the curve giving you the option to select one of these channels. But there are not there ..... any idea what I might be doing wrong ?

I checked and the photo is processed with PV 2012.

Cheers,
Remko

Have you clicked on the small square button in the lower right hand section of the panel to activate the Point Curve functionality?
