Canon PowerShot G7 X Mark II Manual

You can apply the same corrections to several images by first selecting 
multiple images in the main window, and then performing correction 
procedures 

Also, you can apply same corrections by copying the recipe of the 
corrected image and pasting it onto the multiple images 

.



Some noise appeared in the periphery of an image after 
correcting [Peripheral illumination] 
You can reduce the noise by using luminance and/or chromatic noise 
reduction of the noise reduction function 

. However, if you had 

applied high amount of [Peripheral illumination] correction to the 
images that have been shot at night or with a high ISO speed, the 
noise might not be reduced.



The image appears with less resolution after correcting 
[Distortion]
You can make the image similar to the one before correction by 
applying more sharpness with the sharpness adjusting function 

.



The colors of the image became weaker after correcting [Color 
blur]
You can make the image similar to the one before correction by 
adjusting the color tone 

 and/or the color saturation 

 to 

make the color deeper.



The result of [Color blur] correction cannot be detected
[Color blur] correction is effective for correcting blue or red color blur 
which occurs at the edge of the highlighted area of an image. If 
conditions do not match, correction cannot be made.

The periphery of the image may be truncated when [Distortion] 
correction is made.

This function enables the resolution of images to be increased by 
removing any remaining aberration related to image-forming capability 
or any deterioration of resolution resulting from diffraction phenomena. 
These optical phenomena cannot be corrected under Lens aberration 
correction 

. Correction is achieved using the designed value of 

each lens. You can correct these optical phenomena in RAW images 
which have been shot with compatible lenses. JPEG, TIFF, S-RAW, and 
M-RAW images cannot be corrected. To use this function, [Lens data] 
for the lens used to shoot images first needs to be downloaded to your 
computer. Before using the Digital Lens Optimizer, it is recommended 
that you set [Sharpness] or [Strength] for [Unsharp mask] for images to 
0.



To use this function, the EOS Lens Registration Tool (version 
1.4.20 or later) must be installed.



The Digital Lens Optimizer is also available for images shot with 
an extender attached to a compatible lens.



You cannot use the Digital Lens Optimizer with multiple-exposure 
RAW images created on the camera.



EF cinema lenses (CN-E lenses) are not compatible.



[Diffraction correction] cannot be used at the same time as the 
Digital Lens Optimizer.
