*1: Indicates the fineness of the outlines to be emphasized. The smaller the
number, the finer the outlines can be emphasized.
*2: Sets how much the outline is emphasized based on the difference in contrast
between the subject and the surrounding area. The smaller the number, the
more the outline will be emphasized when the contrast difference is low.
However, noise at high ISO speeds tends to be more noticeable when the
number is smaller.
