By dividing the image into small areas, the camera
analyzes the contrast of light and shadow between
the subject and the background, producing the
image with the optimal brightness and gradation.
(Auto HDR) Shoots 3 images with different exposures, and then
overlays the bright area of the under exposed image
and the dark area of the over exposed image to
create an image with rich gradation. 1 image with
proper exposure and 1 overlaid image are recorded.
