"A method I find useful when cutting out backgrounds (which was mentioned by someone else recently) is to eliminate from consideration all but the edge of the foreground image by using the Paintbrush. The idea is the put a new semi-transparent layer on top, then paint over the foreground, almost up to the edge. It's pretty easy to do. It's a good idea to release the cursor button reasonably often so undoing a mistake doesn't undo everything up till then (though mistakes can also be fixed with the Eraser). Once the inside edge has been painted, the interior can be filled with the Paint Bucket. The unpainted area can then be selected and used as a mask to eliminate most of the foreground image. If you have a steady hand, well-defined smooth edges can often be painted well enough that no other form of background removal is necessary. I find it works much better than the Lasso tool. For hair, fur, and other rough edges like that, something like the HSV Eraser can be used to eliminate the background pixels near the edge. A nice feature of the painted mask is that it can be blurred, so the Magic Wand tolerance allows the mask to be expanded or contracted. \n  \nEDIT: Something that just occurred to me, which I haven't tried but seems like a good idea, is to make a new layer that just contains the part of the image that was painted over. Then edit the original image with no selections except those to limit the background elimination to specific regions, not worrying too much about interior foreground pixels. Once the edge has been cleaned up, overlay the saved cutout interior, so that any lost interior pixels will be restored. \n  \nANOTHER EDIT: Or perhaps make the cutout-section layer visible, and behind the original image that will be edited. Then any erasures of non-edge foreground pixels won't even be visible during the edit. It will be as if only background and the edge foreground pixels can be edited. Perhaps the mask could even be expanded with a blur to generate a selection that's outside the foreground image, which could then be used to eliminate all but the edge background pixels. I'm not sure if that would make it easier or harder to remove the background. "
