available for selection.
2. Move the black and white sliders to new points on the
histogram.
●
Moving the black slider
to the right will yield
more contrast in the highlight areas of the image,
so that more detail emerges in the highlight areas.
●
Moving the white slider
to the left will yield more
contrast in the shadow areas of the image, so that
more detail emerges in the shadow areas.
Another alternative is to simply click the Auto button, so
that the dynamic range for the image is determined
automatically.

effects of the other action buttons, see the section
