Drag Amplitude
(Darken)
To the right - increases the intensity of the darkening
across all areas of the image. The height of the bottom
orange curve increases.
To the left - reduces the intensity of the darkening and the
height of the curve.
Drag Scale To the left - makes the tool more sensitive to smaller areas
of brightness variation.
This means that smaller areas can be adjusted
independently. Generally the default scale of 10 gives the
best result, but if an image contains small details that need
brightening, a lower scale might give better results.

Graph
Drag the orange graph
(top)
The graph changes as you left-click and drag up on the
graph itself. The graph represents the brighten
adjustments you are making. The gray graph represents
the maximum amount you can drag the graph before
clipping (pink) begins.
The height of the graph represents the level of brightening
applied at each tone level. (Tone moves from black on left
to white on the right.)
When you make direct brightening or darkening
adjustments on the graph or image, the corresponding
Brighten or Darken Compression slider changes to Custom
curve. If you adjust the position of the slider after this it
discards all direct curve adjustments.
When you make direct brightening or darkening
adjustments on the graph or image, the corresponding
Brighten or Darken Amplitude slider changes to indicate the
current curve amplitude. (An amplitude of 100 is the
maximum amplitude a curve can have without causing
clipping.)
Drag the orange graph
(bottom)
The graph changes as you right-click and drag down on the
graph itself. The graph represents the darken adjustments
you are making. The gray graph represents the maximum
amount you can drag the graph before clipping (pink)
begins.
You can use all the
shortcuts below that

directly to the Graph

Changes the tonal band on the graph itself with a
corresponding change in the image. This is useful for
making fine adjustments to a specific tonal band.

Automatically sets the brightening compression to optimum
for that area of the image. A brighter area (e.g. a face)
works best.
