Specifying the Preferences
Select sRGB or Monitor profile for the color space of the monitor. If you select the [Monitor profile]
radio button, click the [Browse] button and specify the profile for the specified monitor.
Select the color matching method for printing with Easy-PhotoPrint from
[Perceptual] and [Colorimetric].
Select sRGB, Adobe RGB, or Wide Gamut RGB for the color space that is applied when
RAW images are converted to TIFF format and saved.
If you change the setting for [Default settings of Work color space], the changed setting is
applied after restarting Digital Photo Professional. However, the changed setting is not
applied to images with the [RGB] mark (2-4) that have been edited (2-14 to 2-16, 3-7 to
3-11) before the setting is changed. You should change the setting for each of the images
using [Work color space] from the [Adjustment] menu (2-24).
The specified color space is added to the ICC profile that is embedded in TIFF images that
have been converted from RAW images and saved (2-29, 2-31).
A color space is the reproducible color range (the characteristics of color gamut). Digital
