To use the Advanced tab:
1. Do one of the following:
x Drag the Brighten or Darken Compression sliders to the left to adjust the bright or
dark pixels. As you drag, an orange area appears to indicate your adjustments to the
curve.
x Left-click on the left side of the horizontal line and drag upwards to brighten the dark
areas of the photo. Try to prevent the orange graph intersecting with the gray area,
which is when clipping begins (shown bright pink).
x Right-click on the right side of the horizontal line and drag downwards to darken the
bright areas of the photo. Try to prevent the orange graph intersecting with the gray
area, which is when clipping begins (shown bright pink).
x Drag the Scale slider to the right to make your adjustments more sensitive to
smaller areas of brightness variation.
x Make adjustments using any of the options in the table below, including on the image
itself.
2. Click Done to apply your settings and close the tool.

Action: Result:
Sliders Drag Compression
(Brighten)
To the right - increases the lightening applied to the darker
areas.
To the left - applies brightening more uniformly to all areas
of the image.
(The name of the slider changes to Custom curve when
you change the curve manually or make adjustments on
the image.)
Drag Compression
(Darken)
To the right - increases the darkening applied to the
brighter areas of the image.
To the left - applies the darkening more uniformly to all
areas of the image.
Drag Amplitude
(Brighten)
To the right - increases the intensity of the brightening
across all areas of the image. The height of the orange
curve increases.
To the left - reduces the intensity of the brightening and
the height of the curve.
If the Amplitude sliders is 0 - no brightening is applied.
If the Amplitude is 100 - 200, the proportional amount of
clipping increases.
In most cases, 110 is the right amount of amplitude. For
images with fine detail in the highlights, decreasing
brighten amplitude preserves the detail.
In most cases it is not necessary to adjust amplitude.
