Viewing and saving RAW images
You can select from two types of image quality for displaying/saving
RAW images: high image quality with false color reduction processing
and noise reduction function (p.52)
color processing and noise reduction function used.
[High quality]
False color reduction processing is automatically applied, and the
image can be displayed/saved as a false color reduced-high quality
image. Furthermore, you can use the noise reduction function
to reduce the luminance noise and chrominance noise.
You can check the effects of the false color reduction processing and
noise reduction function in the edit window or the edit image window
in the [100% view] or [200% view] enlargement display.
In the [50% view] or [Fit to window] display of the edit window, edit
image window, or any other window, the effects of the false color
reduction processing and noise reduction function are difficult to
check, so they are not applied.
We recommend that you normally set [High quality] for a balance
between image quality and display speed.
[View images at high speed (moiré reduction off)] of [High quality]
If you checkmark [View images at high speed (moiré reduction off)],
when the image is displayed in the edit window or the edit image
window, false color reduction processing is not applied.
As the [View images at high speed (moiré reduction off)] setting is the
same as [High quality] other than for display of the image, the image
undergoes false color reduction processing when it is saved and the
noise reduction function is also available.
used, or high speed without false
(p.52)
[High speed]
Since false color reduction processing is not applied, the display
speed of a RAW image in the edit window or the edit image window in
the [100% view] or [200% view] enlargement display, and the time it
takes to save a RAW image is less than in [High quality].
You cannot use the noise reduction function (p.52).
Depending on the image, it may be displayed/saved with false color
or noise being noticeable.
What is the difference between the [High quality] and [High
speed] displays?
The display image quality of [High quality] and [High speed] is the same
except when the image is displayed in the [100% view] or [200% view]
enlargement display in the edit window or the edit image window.
JPEG image quality
You can improve the quality of a JPEG image by reducing their noise
characteristic that occurs when RAW images are converted to JPEG
images and saved (p.34, p.74).
This setting is also effective for JPEG images that have been saved with
a different name.
The extent of the improvement in noise reduction
The higher the JPEG image's compression rate, the more noise is
reduced. When the compression rate is low, the effect of noise reduction
is negligible.
Default value of output resolution
You can set the resolution for RAW images converted and saved as
JPEG or TIFF images (p.34, p.74).
