Using the Advanced tab
Sliders
The Advanced tab has two sliders for brightening and two for darkening. The
Brightening and Darkening sliders control the shape of the adjustment curves,
while the Amplitude sliders control the height of the curves.
The more you brighten or darken, the more you increase the balance of the dark
against the light areas in the image. The Amplitude sliders increase the intensity
of the effects of brightening or darkening.
The Scale slider at the bottom of the tool adjusts the overall adjustment sensitivity
to local variation in brightness. Moving this slider to the left makes the adjustment
more sensitive to smaller areas of brightness variation, which may be beneficial in
some images. For most images, however, leaving the slider in the default position
gives the best result. You can also adjust the Contrast slider to decrease or
increase contrast, or use the Fill Light slider to lighten dark areas of the image.
Graphs
Between the Brightening and Darkening controls are two gray graphs that indicate the maximum amount of lightening or darkening
that you can apply before clipping (shown as bright pink) begins.
Two colored curves appear and change as you drag the Brightening, Darkening and Amplitude sliders - these curves indicate the
amount of brightening and darkening applied throughout the tonal range of the image. Darker tonal areas are on the left, and
brighter tonal areas are on the right. As you move your cursor over the image, a vertical line in the graph indicates the tone level of
the area under the cursor within the tonal range. At times there are two lines because the tone levels for brightening and darkening
are not necessarily the same. This is because brightening is sensitive to maximum color values while darkening is sensitive to
minimum color values.
The Advanced tab is unique in that you can adjust the curves manually, either on the graph itself, or on the actual photo.
Adjustments made on the photo are reflected in the curve on the graph. Adjustments made on the graph are reflected on the photo.
To increase contrast within a tonal range without changing the brightness, apply brightening and darkening simultaneously in
equal amounts by dragging the upper and lower curves up and down, respectively. The area between the top of the upper graph
and the bottom of the lower graph indicates the amount by which contrast is increased.
To use the Advanced tab:
1. Do one of the following:
Drag the Brightening or Darkening sliders to adjust the bright or dark pixels. As you drag, a gray curve appears to
indicate your adjustments.
Left-click and drag upwards to brighten the dark areas of the photo. Try to prevent clipping (shown in pink on the
graph).
Right-click and drag downwards to darken the bright areas of the photo. Try to prevent clipping (shown in pink on the
graph).
Drag the Scale slider to the right to make your adjustments more sensitive to smaller areas of brightness variation.
Drag the Contrast slider to increase or decrease contrast in your image.
Drag the Fill Light slider to add light to the dark areas in your image.
Make adjustments using any of the options in the table below, including on the image itself.
