Next, let’s take a look at the Contrast slider. Move it to the right, and you’ll
see the highlights and shadows getting taller in the Histogram panel. This means
you have more contrast in your image; more contrast means a larger difference
between dark and bright values. Moving the slider to the left makes the shadow
and highlight bumps shorter, and slightly elevates the midtones. This results in a
flatter image because there’s less difference between the darker and brighter values.Checking the Use Legacy box simply takes away those algorithms, and you can
see what the tool does in its raw form. Moving the Brightness slider moves all the
values to either side, and moving the Contrast slider expands or shrinks all the val-
ues along the x axis (horizontal). This nonlinear method is undesirable for photo-
graphs but can be very useful when dealing with masks.
