About Effects
Natural
For images preserving a wide tonal range where the highlight and
shadow detail would otherwise be lost.
Art standard
While the highlight and shadow detail will be better preserved than
with [Natural], the contrast will be lower and the gradation flatter to
have the picture look like a painting. The subject outlines will have
bright (or dark) edges.
Art vivid
The colors are more saturated than with [Art standard] and the low
contrast and flat gradation create a graphic art effect.
Art bold
The colors are the most saturated, making the subject pop out and
the picture look like an oil painting.
Art embossed
The color saturation, brightness, contrast and gradation are
decreased to make the picture look flat. The picture looks faded and
old. The subject outlines will have bright (or dark) edges.
