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
correctly exposed image, the bright areas of an under exposed
image and the dark areas of an over exposed image to create
an image with rich gradation.
2 images are recorded: an image with the correct exposure
and an overlaid image.
