You can make corrections to any of the five aberrations as below, either
one at a time or simultaneously.
Peripheral illumination
Chromatic aberration (color fringing which occurs in the periphery of
an image)
Color blur (blue or red color blur which sometimes occurs at the edge
of the highlighted area of an image)
Distortions Diffraction
1
Select an image in the main window.
2
Display the Lens Correction tool palette and
checkmark the items to be corrected.
The image is corrected and redisplayed.
In the main window, the [ ] mark is displayed on the image to
indicate that the lens aberration correction is applied (p.166).
Making Corrections
Enlargement display section
Check the results of corrections to peripheral illumination or
distortions in the full view.
Check the results of corrections to chromatic aberration and color
blur by clicking the area on the image you want to check and
then checking the enlargement display section in the top of the
window. You can choose from 4 display scales between 1:1 and
1:4 for the enlargement display.
You can lessen the degree of correction by moving the slider to
the left.
You can respectively correct red chromatic aberration with the [R]
slider of the [Chromatic aberration] or blue chromatic aberration
with the [B] slider.
To correct distortion aberration of images shot with a fisheye lens
(EF8
–15mm f/4L USM Fisheye or EF15mm f/2.8 Fisheye), four
effects can be selected from the [Effect] list box in addition to
[Shot settings] normally used for distortion correction.
The level of an effect can be adjusted with the adjustment slider
located below [Distortion].
For detailed information on each effect, see “Effects of Distortion
Correction for Fisheye Lenses” (p.75).
For images shot with EF8
–15mm f/4L USM Fisheye, a fine-tune
slider is also displayed when you select [Emphasize Linearity]
from the [Effect] list box.
Adjust the amount of correction for distortion aberration with the
adjustment slider, and then adjust with the fine-tune slider if more
adjustment is required.
When the list box for selecting an extender is displayed, select
the extender attached at the time of shooting from the list box.
[Diffraction correction] corrects only those images shot with a
camera with a diffraction correction function. By checkmarking
this option, images are corrected according to the camera’s
diffraction correction function. Note that this function cannot be
used at the same time as the Digital Lens Optimizer.
The adjustment range of distortion correction is either [0 to +100]
or [–20 to +120], depending on the camera model that was used
for shooting. The adjustment range for images shot with a
fisheye lens mounted is [0 to +100] regardless of the camera
model that was used.
