Photoshop help - how do you save a channel?

[Picture North Carolina]

In CS2, when you go to the channel pallet and clilck on a R, G, or B tab, you see the black and white representation of that channel.

I was working with a pic and clicked the B channel and really liked the black and white image I saw, but I cannot figure out how to save that channel only in B/W form. How is that done? Thanks /Dan

Try adding a channel mixer adjustment layer to the image. This way you can adjust the settings to the specific channel you desire without changing original image.

I tried it, but it did not work. Perhaps an image will help describe what I am trying to do.

The unprocessed color image I am working with is on top. When I do nothing other than load it into photoshop, click the channels tab then click blue, the bottom is what I see (example is from a screen capture). This is what I see for the blue channel and what I want to save.

You cannot see it in this scaled version, but in full size it looks like a wood etching and I want to print it as a BW image. When I convert the image to BW, it does not look the same. It is the blue channel only that contains the etching appearance, so desaturation or convert to BW does not work. How can I save that blue channel only as I see it when editing? /Dan

Right-click on the blue channel
Select "Duplicate Channel..."
In the dialog set "Destination", "Document:" to New or whatever name you wish.

With the channel mixer adj. layer, you check the box 'monochrome' , and set R=0; G=0; B=100. Non-destructable, reversable, adjustable. Simply put: More able ;)

Wow! Paul and Rene, thanks! Paul's method worked perfectly producing what I was seeing in channels. Rene, your method did not produce -those- specific results (the blue channel mono was a lot more contrasty), but it -did- yield it's own benefit. By employing the channel mixer method, the other two channels were still left available for tweaking which afforded more control and flexibility. You'e both geniuses! Thank you much. /Dan
