Step Three:
The filter automatically calculates what it thinks is the amount of camera shake based on
how many pixels it thinks have moved, but if the auto method doesn't look good, it may be
that it either needs to affect more or fewer pixels. That's what the Blur Trace Bounds slider
is for.This slider controls howmany pixels the filter affects (kind oflike howthe Tolerance
slider for the Magic Wand tool determines how far out the tool selects). Dragging the slider
to the left affects fewer pixels (so, if there's just a little blurring, it may need to affect fewer
pixels) and dragging to the right affects more pixels. Its own estimation is pretty darn good
but, again, you can override it (in this case, I only moved it a little). If you get ghosting (as
we did here) or other artifacts, drag the Artifact Suppression slider to the right a bit (here, I
dragged it to 45%).
