Focus Shift: Tips

l
Although you can reduce the number of shots by increas-
ing the step width, if the step width is greater than the
depth of field, you may notice a mix of in- and out-of-focus
areas when the photos are stacked.
The photos for this stack were shot with a focus step width of 10. A mix
of in- and out-of-focus areas is visible on the wings.
Setting the focus step width to 3 produces a smooth stack with no out-
of-focus areas.
Out-of-focus areas will be less obvious at lower resolu-
tions. Check for out-of-focus areas after scaling the image
to the desired size.
