hi,
when you convert a path into a selection, does it go strictly by the line of the path, or does it take into account the difference in color, and maybe bend around some curves to make the selection more precise?

There are some differences between version 3 -> 5 on this, however in most cases they path line is the dividing point.  Once the rough selection is made the next step for the computer is seprating colors, then levels, then contrast.  The higher the pixel value, the less acurate the selection.  However, sometimes a precise pixel values like 0.2 can cause stairstep selections which usually is never wanted.

I am using 4.01; so if I want to, let's say, crop out a person's head from a considerably lighter background, I wouldn't have to have the path match the curve exactly to the pixel, I could just ballpark it? within reason of course.
