Changing an Image’s Brightness, Contrast, and Other Settings
You can change the brightness, contrast, and other settings of images to improve their
quality or to create interesting effects. Adjustments you make don’t affect the original
image; they affect only the image’s appearance in Keynote.
To adjust an image:
1
Select the image.
2
Choose View > Show Adjust Image.
3
Use the controls to make adjustments.
Enhance button: Automatically adjusts the image.
Brightness: Adjusts the lightness of the image.
Contrast: Adjusts the contrast of light and dark tones. You can make shadows darker,
sharpen the edges of objects, and make colors stand out more. If you increase the
