How often do you use channel selections to DNB?

Just a thought... how often do you use channel selections to DNB?

Re: How often do you use channel selections to DNB

This is an interesting question. I used to often D&B on individual channels with one window (active) open as the target channel, and a second window showing the RGB results. I stopped doing this a while back because when I upgraded (I think it was to CS6) I couldn't seem to get the two independent windows(single channel view and RGB) up any more.
At that time the shortcuts Cmd 1,2,3 and tilde referred to R,G,B and RGB respectively.

How can you see RGB in one window and a channel in another simultaneously?

Can this be done in layers as in see adjustment layer mask in one, and entire image in another?

As I said, I don't know if you can now, but it used to be possible, with two windows up, to select the target channel using the keyboard shortcut. This would show the active window as that channel and you could then D&B on that channel only while viewing the composite RGB results in the other window.

Actually, I think you still can.

Yes you can.

Menu\Window\arrange\new window for xxxx

You still can view one window in individual channel while the other in composite (whatever color space)

ADOBE just moved it from bottom of menu\window to Menu\Window\arrange if my memory serve me well.

It is an interesting idea though, it is worth a try, however, I would do it slightly different, I would go LAB for it, so I may work only on luminosity without affecting or causing color shift. It is just a theory, I did not try it yet.

We went so far off the subject
The actual toipc was about doing this:

Select channel> DNB while that selection is active

Re: How often do you use channel selections to DNB

So would you be observing the effects of your D&B in colour or as a greyscale channel?

Re: How often do you use channel selections to DNB

Both, gray in the channel window, color in the composite window, however, you would have to let go of the mouse or pen key for the effect to show up in the color widnow.

I can't help but laugh. It's not about preview, it's about actual drawing.

AK, I blame you for this detour, you implanted a bug inside my brain, but now pretty please can we go back to the initial topic. ahahaahaha I'm laughing out loud

I find it quite usefull especially when dealing with things like pattern and hair to dodge and burn with a selection. Meaning:

Select a chanel, RGB for example, then paint on Burn layer. It gives me more precision in ares that have a lot of detail, so rather then drawing all that detail, I already have it in the brush.

That's what I'm asking.

Aha - I think I now understand what you mean. Load a channel AS a selection and then use that selection to mask your D&B work? Is that it?

Yep! .

FYI, with the release of CS4 or CS5, Adobe made a number of disruptive changes to some of the most important shortcuts. Ctrl ~,1,2,3 is now Crtl 2,3,4,5 respectively.
