Hi, make sure to take a look at all of the channels, sometimes you can find one channel that has some contrast and you can begin with that. Be sure to look at all the channels, make copies in Lab and cmyk and examine all the channels to see if there is a good starting point.

Post a pic - this would help us help you better.

Aside from that - if there is no contrast or the selection is just too difficult you may just end up painting your mask with a tablet. For individual hairs - you may have to paint those in… Hair is one of those things that isn’t easy when the photo is not taken correctly. A lot of handwork usually is the answer.

I would look at the magenta and black channels in CMYK. Overlay the black onto a copy of the magenta, it will get you started. Paint with a soft brush in overlay mode around the edges to clean up. Again, this would be a starting point. Also I would use the pen tool on the sweat shirt.

Hope that helps.

thanx, it did a good job on the top hair, but its not doing so well on the right side where the hair is more blonde there = more bright = bad contrast from background
and also in the left side near the neck there is some background view that is not selected well using the brush and overlay mode (it paint some of the background as well)

yeah, it takes some going back and forth a bit to get right. That is just a starting point, Often, I will get the mask as close as possible, then I will dupe the layer, use the selection to make a layer mask and put a color background behind, then paint on the mask where needed. I use a hard edge brush then use the blur tool to soften where needed in the end.

If you want to get some ideas on how to select ANYTHING complex, including 10 ways to select hair, pick up this book: Photoshop Masking and Compositing by Katrin Eismann. It is a great book.

That’s the same book I have. she does a good job, and alot of what I suggested was inspired from her book. The only thing with that book, IMO, I was looking for more, I guess I had a good grip with the stuff she was showing and I expected to be over-whelmed and I wasn’t. There is only one book I can truly say I learned stuff from that was over-whelming, in a good way and that is the Lab book http://www.amazon.com/Photoshop-LAB-Color-Adventures-Colorspace/dp/0321356780

It has it’s own way of selecting and isolating, but it is really more about color. Great book, seems I mention it here alot :wink:

Also, another fun book is Scott Kelby’s book on channels. Great for just picking up and looking through from time to time, layed out really well with an at a glance style.
