And why wont that work? It's annoying and a lot of work, but I'm pretty sure that it works.

Re: Help with Hair Mask

Trust me, brush masking hair is impossible. You are better off getting rid of the hair and brush painting or smudging new hair back.

Re: Help with Hair Mask

Ok, here are some thing you might try

Convert to HSB channels with the HSL/HSB plugin. That plugin will substitute the rgb channels with hsb channels. The image will look horrible, but you can use those new channels for creating initial alphas. The hair is more saturated than the background, so it will be brighter in the S channel. You can even help it by boosting yellows and yellows only before you convert to HSB.

Try LAB. Duplicate the B channel and compress it with levels till you got an alpha that you can work with.

If i find some time I will put these to to the test and show you if they work.

Re: Help with Hair Mask

I find that very interesting. It's weird because pretty much every hair mask I've ever done, you can start with channels or whatever, but in the end I always end up brushing detail back. Or sometime when there's nothing of use in the channels, I just brush a mask.

I don't think it's impossible. It's not the easiest thing, or the most fun, or even the thing I'd recommend, but it can be done.

Re: Help with Hair Mask

Tweaking an alpha channel with a brush is very different to creating an alpha channel for hair with a brush from scratch. There's variations of opacity, color contamination and softness that is just impossible to mimic by hand. You need something to start off with.

This is done with calculations. I think it's not usable.

Re: Help with Hair Mask

flexmanta is right, creating hair masks is a big part of my job, using LAB and using good hair brushes plus shooting another image of her hair on a color that is close to the color you are placing her on is the only solution.

Re: Help with Hair Mask

Another approach is to make a reasonable mask and select a new BG which is closer in color to the hair. For this purpose CS5's new Refine Edge was a reasonable compromise. My thoughts are pretty much aligned with Flexmanta on this image.

Re: Help with Hair Mask

Hi guys,

interesting picture I just tried mistermonday's version with desaturated background and Mask Pro 4.1 - it is not impossible, you can spend more time on it and be more precise than I was. BTW - how did you desaturate just the background, mistermonday?

Re: Help with Hair Mask

I have CS3 - so Color Range is the best solution for this kind of background desaturation? It takes time as well ...

Re: Help with Hair Mask

Creativeretouch, to desaturate the BG I temporarily converted the image to LAB color. Added a Hue/Sat adj layer and with 2 clicks on the background it was completely desaturated without affecting anything else. That will work in CS3 or any other version of PS.
Regards, Murray
