Adjusting an image that is too dark/bright
The best way to lighten or darken an image is to use the exposure slider.
For more precise and advanced control, the exposure slider should be used to centre the data
within the histogram and define an initial exposure, ensuring that no highlight or shadow clipping
occurs. When this stage has been completed, use the levels controls to fine tune the lightness
and darkness of the mid-tones of the image.
How to use the image adjustment slider
Sliders provide the best way to adjust exposure and contrast. Use one tool at a time before
moving onto the next tool.
Exposure
Adjusts the exposure in much the same way as the controls on the camera do. The slider is
calibrated to provide a range of +/- 2.5 stops.
