Erase Photo Backgrounds Seamlessly with Photoshop

I’m a pretty experienced Photoshop user and even I am blown away by how many tools this program has. This one, to erase the background in a photo, is pretty useful which I could have used on a photo but ended up using the old school lasso tool to do this. I wonder if to works well on a background that isn’t one color or tone. Still, nice for photo collaging and more. [ via ] Link.
