R Processing RAW Images with the Camera
Color space (p.200)
You can select either sRGB or Adobe RGB. Since the camera’s LCD
monitor is not compatible with Adobe RGB, the difference in the
image will hardly be perceptible when either color space is set.
Lens aberration correction
Peripheral illumination correction (p.194)
A phenomenon that makes the image corners look darker due to
the lens characteristics can be corrected. If [
Enable ] is set, the
corrected image will be displayed. If the effect is difficult to
discern, magnify the image (p.395) and check the four corners.
The peripheral illumination correction applied with the camera will
be less pronounced than that applied with the Digital Photo
Professional (p.552) at maximum correction amount. If the effects
of correction are not apparent, use Digital Photo Professional to
apply the peripheral illumination correction.
Distortion correction
Image distortion due to lens characteristics can be corrected. If
[
Enable ] is set, the corrected image will be displayed. The image
periphery will be trimmed in the corrected image.
Since the image resolution may look slightly lower, adjust the
sharpness with the Picture Style’s [
Sharpness ] parameter setting
as necessary.
Digital Lens Optimizer
By using optical design values, the lens aberrations, diffraction,
and degraded resolution due to the low-pass filter can be
corrected. Check the effects of the [
Enable ] setting with the
magnified view (p.395). The unmagnified view (normal view) will
not show the effects of the Digital Lens Optimizer. When [
Enable ]
is selected, although the chromatic aberration correction and
diffraction correction options will not be displayed, both will be
applied to the processed image.
