The Adjust Sliders section contains four slider controls plus a curves graph that plots the
tonal relationships in the picture. Whereas the Samples thumbnails provided a one-click
adjustment, the controls here allow multiple, additive, fine-tuning changes.

The best approach is to select a style of curve adjustment first, e.g. Lighten Shadows, and
then fine-tune the results with the sliders. To reset the Curves feature back to its original
position click the Default style entry or the Reset button in the top right of the dialog.

Adjust Color Curves workflow:
1 Open color image and Select Enhance > Adjust Color > Adjust Color Curves.
2 Select the base curves adjustment style from the options on the left of the dialog.
3 Use the slider controls to fine-tune the results and then click OK to apply the
changes or Reset to start again.
4 To reset the feature and remove any current adjustments click the Reset button.

BEFORE AFTER

The Posterize feature is
used to reduce the total
number of color levels in
an image.

Editor: Filter > Adjustments > Posterize
The Posterize feature reduces the number of color levels within an image. This produces a
graphic design-type illustration with areas of flat color from photographic originals. This
type of image has very little graduation of tone; instead, it relies on the strength of the colors
and shapes that make up the image for effect. The user inputs the number of tones for the
images and Elements proceeds to reduce the total palette to the selected few.

Posterize workflow:
1 Select Filter > Adjustments > Posterize.
2 Input the number of levels required.
3 Select OK to finish.
