A change of gradient means a change of gain. When a gamma value with

twice the gradient is set for only half of the input, 256-step output will be

obtained.

However, note that setting a gamma value with a sharp gradient toward the

black side means amplifying the noise element.

In addition to an auto-LUT function, the LS-4500AF has an LUT function

set by users, enabling downloading from an outside source.
