P: Switching channels deselects curves point in Photoshop 27.5 on macOS

This is utterly infuriating that it has not been addressed. Most response we’ve had from Adobe here is that they CAN reproduce it…..and yet still solicited system info from users (which effectively kills the thread here)….

...and yet nothing has been done about it and no acknowledgement that it is even on their radar.

As in, they know about it, they just don’t think it’s a priority.

I assure you Adobe, this is a HUGE issue for professional users, most of whom don’t have time to amplify its importace in this forum.

27.8 disappointingly does not fix this problem. Very disappointed.

The curves layer adjustment in versions before 27.0 always had a thin line for the curve, and the grab points were small and unobtrusive. The Red, Green, and Blue channel curves also showed their colors once they were adjusted. Now all channel curves are black and clunky and if RGB and one or more channels are adjusted, they can not be differentiated.  Is this a bug or was this intentional? If it was intentional then that was a big mistake. Please go back to the thin lines.

I’m very happy to see that this is not an unusual workflow and that Adobe is working on fixing this. Because for me, this is something I do on EVERY image I work on. And making me reselect my black (or whichever) point every time I switch channels is like having to step around broken glass while barefoot when I was used to running.

27.7 the problem is not fixed. Continually in my thoughts and workflows.

Can confirm that I’m also dealing with this bug. It started in 27.5 and has carried through to 27.6. It’s also in the Beta versions. 

27.4 is the last “good version” when switching channels does not deselect the active curve point. 

I am also having this problem and would love to see it addressed

I’m also having this problem and I’m looking forward for the matter to be resolved.

I strongly agree. While I can reluctantly accept the thicker curve and larger control points making the UI feel more childish, this change breaks a fundamental behavior of the Curves tool. Previously, the nearest control point would remain active when switching channels, allowing immediate adjustment with the arrow keys. In the latest version, all points become inactive, forcing users to reselect them with the plus/minus keys. I cannot believe this was implemented and released without preserving such a basic and essential interaction.

In previous versions if I had adjusted a point on the red channel and left it selected I could switch to the green or blue channel and a similar point if it existed would remain selected.

Recently this functionality disappeared, now switching channels causes all points to be unselected. This adds extra friction in adjusting tonality. 

Specifically it slows down those of us who very quickly manipulate multiple channels using only the keyboard. The workflow used to be: 

starting on the red channel
move point with arrow keys

option 4

move point

option 5

move point

option 2 

fine adjustment

option 3

fine adjustment
 

….and so on, all of this taking place in a couple of seconds while never taking our eyes off the image.

Now it’s

option 4

find the right point, is that it? nope, its the next one

make adjustment

option  5 

search for the right point, click it, whoops I moved it. nudge it back,
now i’ve taken my eyes off the image.

at this point I have not even adjusted one image where previously by now I’d be on the 3rd or 4th.

Additionally this change seems to add no functionality whatsoever.

Can we please have it back?
