Re: The Double-Hair Masking Technique

i use multiple layer duplicates set at different layer modes to get my final masking done, if that's what you're referring to?

Don't know if this is similar to what you're after. I wrote this a while ago. It's a double mask technique--not necessarily hair.

Hi there

It is a Katrin Eismann technique

You use a channel to make your mask… then duplicate the channel .

On one channel you use the Maximum filter at a low setting 1 pixel will do… to shrink it just a little.

In you main document make a couple of duplicates… add the luminosity selection of the smaller channel to the top duplicate.

Then add the luminance of the larger channel to the second duplicate below....but change the layer mode to multiply.

The small difference between the channel sizes will show as multiply…darkening the usual fringe.

You may need to add a small amount of blur to blend between the two.

Great catch, Butch...

Just looked it up. This method, attributed to Colin Woods, is described in detail and richly illustrated in Katrin's Photoshop Masking and Compositing book, pp. 369-372. It assumes one is using an evenly colored stuido backdrop, e.g., white or green screen.

Re: The Double-Hair Masking Technique

hello butch and others
this sounds fascinating and like a great thing to try, but I don't understand what you mean when you say: add the luminosity selection of the smaller channel to the top duplicate. what is the luminosity section?
Am I being really stupid?
please help
