distortion. Select
Auto to let the camera
correct distortion automatically and then
make fine adjustments using the multi

not available with photos taken using
auto distortion control; see page 316). Press

distortion, 4 to reduce pin-cushion distortion (the effect can be
previewed in the edit display; note that greater amounts of
distortion control result in more of the edges being cropped
out). Press

control may heavily crop or distort the edges of copies created
from photographs taken with DX lenses at image areas other
than
