Can anyone tell me about their experiences with Knockout? I have a project that requires me to extract just the heads of people from photographs and when they are against backgrounds that are the same color as their hair, I can't seem to do a good job. I am specifically interested in how good Knockout really is - (the demo on the Corel website is awesome but all the examples are on backgrounds that would be easy to get rid of anyway) - and also in how steep is the learning curve. I know the bare-bones of PhotoShop. Being new to graphics, I found PS difficult. Any help much appreciated. Thanks, all.
