Hey guys, I've just started playing about with photoshop and have CS4, with the intent to bring some of my drawings to life. I thought playing around with some skins would be a good way to learn what does what. Having watched some tutorials, macks white removal seems to be an essential - however it is not compatible with newer versions of PS. Having checked through most of the filters that are available and finding nothing i hoped someone might be able to point me in the right direction ?
