4-3 Adjusting Brightness and Contrast
Adjusting an Image in the Preview Window
Brightness
This adjusts the overall brightness. Mak-
ing the value too large can destroy the
balance, so it may be a good idea to ad-
just it to the absolute minimum necessary.
Contrast
This mainly adjusts highlights (the bright-
est areas) and shadows (the darkest areas).
Using this can be effective when you want
to achieve a sense of tension with a good
balance of light and dark.
Gamma
This mainly adjusts the brightness of tones
of intermediate brightness between bright
and dark areas. Using it is effective in ad-
justing the overall brightness.
The dark and bright areas are printed as shown in the figure.
Dark-color areas are not struck, and light-color areas are struck forcefully.
Also, the printing results before and after adjustment are as shown below.
