Help with Hair Mask

Hi guys,

I recently did a mini shoot with a friend of mine. Regrettably I had to shoot her against a sandy colour wall which has made extracting her blonde hair a nightmare.

I'll be the first to admit that I really struggle with hair, and this occasion has been no different. I have tried the following techniques:

1) Masking using channels;
2) CS5 refine mask techniques;
3) Pen tool.

None of them have worked for me.

In desperation, I downloaded a few Hair Brushes, with the intention of cutting around the head and then drawing those blonde wisps camera left back in, but again with no luck.

My problem with this latter approach is that whilst I have some great hair brushes which would work a treat, I'm unsure how to use them. I've tried clone stamp using the models hair as a source but it looks naff, and if I use as a normal brush, the solid colour looks unrealistic. I have also tried playing with blend modes but again no luck.

Here is a link to the DNG, if somebody could have a play and create a good mask of the hair then I'd really appreciate it, as I've spent days trying to nail this.

If anyone manages a decent mask then a little explanation of what was done would be helpful for others:

DivShare File - Hair.zip

I'm sure some of the Photoshop Gurus who grace this forum will find this easy!

And yes, the moral of this story is to pay more attention to your background!

Thanks and good luck!

Matt

Re: Help with Hair Mask

Matt,
I find masks fun and challenging. After viewing your image, I'm thinking that working in CMYK and exploiting some things in the K channel may work well for starting off. Had you been down that path yet. I'm limited on time right now, but will check back tomorrow.

Re: Help with Hair Mask

@Tommyo, i normally find mask challenging but this one has been a right pain!! I haven't tried switching colour spaces so will give CMYK a try!

@Flotsam, tried most of the Russell Brown tutorials but missed the one you highlighted so will have a look.

I've heard good things about Topask Remask, so may have a try with that too. If i can get a half decent mask then I'm hoping i can finish things off drawing back in the hair with brushes.

Thanks for the help so far!

Anybody else up fo having a go for me?!

Re: Help with Hair Mask

I tried with all the methods that you have mentioned above and I also tried to get it done with topaz remask. I'm afraid this is an impossible mask (for traditional masking). Not only the background has shares the same color with the hair, but it's also very randomly textured. Those 2 facts render most masking techniques useless.

I said it's impossible for traditional masking, but nothing is impossible. My guess is that you'll have to create your own hair from scratch or by using the same model on a different background... or just re-shoot.

Re: Help with Hair Mask

Try another way, disguise the background.
I put another picture on top and only save the girl by mask; leaving
some of the background to show.

Like this.

Re: Help with Hair Mask

Meet your new friend: the quick mask.

Press Q, (actually double click that little icon first, set it up so that what you select turns green), and grab a brush. Then sit down and mask out the hair. By hand.

Yes it's annoying. Yes it takes time. But it works.

Good luck.

I'm afraid that won't work unless your last name is Botticelli.

Re: Help with Hair Mask

As said before......watch what background you are using next time....that's the bottom line in this case.... this one is a tough one to mask.

Re: Help with Hair Mask

Matt, there is enough separtation between the yellows in the lady and the background to quickly neutralize the background. If you leave it gray without removing it the lady still stand out. If you wish to remove the BG, you will have some work to do because you have a wide range of luminosity and no delineation of it between the BG and hair. You could make a difference layer between the original and gray BG and finess a mask out of that difference.
Regards, Murray
