"Gradation allows the camera to process images in various fashions suited to subject
scenarios. It applies tools that affect the brightness and contrast of the processed image.
The value of gradation is that the photographer can select the look of the image in-camera
when shooting or change the gradation of a RAW image after the fact using the RAW
EDIT function. (Changes are saved as separate JPEG images.)
The Gradation options are found in the camera's Picture Mode submenu. There are four
options:
AUTO – This option divides the image into detailed regions and adjusts the brightness
separately for each region. This is effective for images with areas of large contrast in
which the whites appear too bright or the blacks appear too dark. It is a form of Shadow
Adjustment Technology. Photos with a greater range of light like landscapes and night
scenes would benefit from this option.
NORMAL – No gradation algorithms are applied to the images.
HIGH KEY – Gradation is applied that best suits a bright subject, such as silhouettes on a
foggy day. It processes images so they are bright with slightly higher contrast in the
brightest areas.
LOW KEY – Gradation is applied that best suits a dark subject that NORMAL gradation
would tend to process lighter. It can be used to make images that have a somewhat
somber mood.
The best way to see the effects produced by gradation is to take the same shot with each
of the options and in the camera's Playback Mode, display them on the LCD in the four-
shot display option to compare the differences. Remember to change the option back to
AUTO or NORMAL after you have finished with a HIGH KEY or LOW KEY subject.
You can also use HIGH KEY and LOW KEY creatively for unique subjects or scenarios
such as a high key or low key portrait to create a mood."
