Distortion Control
This option produces a copy with reduced barrel distortion (a bowing out effect) or pin-
cushion distortion (an inward-bending effect), both most noticeable at the edges of a
photo. You can select Auto to let the D3100 make this correction, or use Manual to
make the fix yourself visually. Use the right directional button to reduce barrel distor-
tion and the left directional button to reduce pincushion distortion. In both cases, some
of the edges of the photo will be cropped out of your image. Press OK to make a cor-
rected copy, or the Playback button to exit without saving a copy. Note that Auto can-
not be used with images exposed using the Auto Distortion Control feature described
earlier in this chapter. Auto works only with type G and type D lenses (see Chapter 11
for a description of what these lenses are), and does not work well with certain lenses,
such as fisheye lenses and perspective control lenses.
Fisheye
This feature emulates the extreme curving effect of a fisheye lens. Use the right direc-
tional button to increase the effect, and the left directional button to decrease it. Press
OK to make a corrected copy, or the Playback button to exit without saving a copy.
