eraser tool tolerance

[madreel]

The background eraser tool will not let me adjust tolerance no matter what I do.i keep ending up with selections that have left over pixels that need to be removed but I cant adjust the tolerance so it either removes to much or not enough.Help please. I tried using the paint select method but still I get them hard extra pixels and when I paste the selection on to another layer to combine it with the bottom photo layer it looks horrible. The two photos do not blend smoothly.

The background eraser attempts an auto-tolerance, when that's on there is no ability to change the tolerance. Look for the checkbox on the tool options panel that says "Auto-Tolerance" and deselect that.
