"Yesterday, just for the heck of it, I tried removing the background from a picture of Humphrey Bogart posted on a thread about cutting out backgrounds. I'd forgotten how useful the Erase tool can be when the edge is smooth. Painting a mask layer is better for more complex situations, but for simple edges, just erasing the background is quick and quite easy. Generally, it works best to use a reasonably large brush size. The HSV Eraser was mostly written to handle tricky situations like hair and fur. Those are difficult because the background and foreground are mixed together, so many of the pixels are half background and half foreground. If the colors are similar, then those pixels can usually be left unchanged and later feathered. If the colors contrast, then hopefully the HSV Eraser's partial-erase feature can be used to eliminate the background color while leaving the foreground color. \n  \n(Of course, if you can generate different backgrounds for the same image, that makes things a lot simpler, and is far better than erasing or painting a mask.)
