3 Selecting a Picture Style
R Landscape
For vivid blues and greens, and very sharp and crisp images.
Effective for impressive landscapes.
S Neutral
This Picture Style is for users who prefer to process images with
their computer. For natural colors and subdued images.
U Faithful
This Picture Style is for users who prefer to process images with
their computer. When the subject is captured under a daylight color
temperature of 5200K, the color is adjusted colorimetrically to match
the subject's color. Images will appear dull and subdued.
V Monochrome
Creates black-and-white images.
Black-and-white images shot in JPEG cannot be reverted to color. If you
want to later shoot pictures in color, make sure the [Monochrome] setting
has been canceled. When [Monochrome] is selected, <0> will appear on
the top LCD panel.
W User Def. 1-3
You can register a basic style such as [Portrait], [Landscape], a
Picture Style file, etc., and adjust it as desired (p.141). Any User
Defined Picture Style that has not been set will have the same
settings as the [Standard] Picture Style.
