Exposure Panel |
The Exposure paned lets you adjust the exposure of the foreground or background image.
The Controls:
Brightness – This slider will determine the overall brightness controls. Unlike other brightness controls it tries to keep color in over exposed areas.
The supplied princess and the cat image could use a little exposure correction.
If we move the brightness slider to the left the image becomes even darker, not what we want.
Moving the brightness slide to the right makes it brighter and is a better exposure.
Contrast – This slider will make light areas lighter and dark darker.
Here is our princess with a bit more contrast. The brightness and contrast sliders work together so when you adjust one you may need to adjust the other.
Saturation – This slide is not used as much as the others but it can be used to make the colors more or less vivid.
Shown here is a slight increase in color
Enhance Shadows – This will being out detail lost in dark areas
Hard to see here but look at the princess’s dress you can see there is more blue in what was black areas.
Reduce Highlights – This slide will reduce only the brightest areas of the image. Details in these areas are often lost when you increase contrast.
Here we reduced the highlights slightly. Notice that the white cat is not as white as before.
Enhance Local Contrast – This slider provides some sharpening capability. Its effects are only noticed in the high resolution output. This can help small hairs that would be lost to show up because it increases the difference between the hair and the local background.
