Looking through the Help section I can see nothing refering to a black channel.
Can any of you good folks help me out here?
P.s I notice Peter has the same problem a few threads back too. Problem also crops up on a couple of other actions too.

re: black channel
RGB mode (red, green, blue) will not have a black channel.
CMYK mode (cyan, magenta, yellow, & black) has a black channel.
I'm assuming the creator of the action was using CMYK as the basis for the action.
Thank you for that, I will go and give it a try.
The article leaves out some steps that are important, if you want really good results. For example, it does not use Blend If to keep sharpening away from the highlights and the shadows.
My TLR Sharpening Toolkit is a free download. It is a sophisticated Photoshop action set for sharpening images.
The toolkit is based on the three-pass sharpening philosophy described by Bruce Fraser, although it can also be used for single-pass or two-pass sharpening. I engineered this toolkit to include the best features of commercial sharpening tools, like Focal Blade and Photokit Sharpener. Features include:
• Sharpen with Highpass Filter or USM sharpening.
• Sharpen edges and surfaces separately (or either alone).
• Sharpen light and dark pixels separately.
• Generate masks using luminosity or color boundaries or a composite of the two.
• Brush in creative sharpening/blurring.
• Blend If settings protect against sharpening highlights and shadows.
• All sharpening is done non-destructively using layers.
The action set comes with illustrated instructions in PDF. I also have tutorials, tips, and a learning gallery to help with sharpening.
Hello .thanks for a terrific site and all your contributions.
Sharpening has always been my problem. Jeaniesa mentions John Houstons sharpening technique and another technique for lightening shadows.
Would it be possible to put a link to the posts mentioned .many thanks
Re: "Smart Sharpening" Technique
the fastest way to sharpen an image is by "UNSHARP MASK" however it may sharpen all the iamges and will create ugly noise.. so the best way is go to channel and choose what channel (can be one or two channels) you would ONLY sharpen (not the four channels) and presto you will see a great result!
