154 Menu Guide
Create copies with reduced peripheral
distortion. Select Auto to let the camera
correct distortion automatically and then
make fine adjustments using the multi
selector, or select Manual to reduce
distortion manually (note that Auto is
not available with photos taken using
auto distortion control; see page 44).
Press 2 to reduce barrel 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
J to save the retouched copy.
