If you adjust the exposure settings, the settings are saved as part of the view properties. The next time you
render this view, the same exposure settings are used.
To adjust the exposure of a rendered image
1 In the Rendering dialog , under Image, click Adjust Exposure.
2 In the Adjust Exposure dialog, specify the desired settings.
See Adjust Exposure Settings on page 1169.
3 Click Apply to see the results of the changes in the rendered image.
4 To return to the default exposure settings, click Reset to Default.
The default Exposure Value is optimized for the selected lighting scheme. Other exposure settings
have neutral settings.
5 Click OK to return to the Rendering dialog.
Adjust Exposure Settings
When rendering an image , exposure control (or tone mapping) is just as important as the lighting and
materials used. Exposure control helps to convert real-world luminance values into a realistic image. It
mimics the human eye response to luminance values with regard to color, saturation, contrast, and glare.
Use the following settings to
adjust the exposure of a rendered image.
Description Setting
Overall brightness of the rendered image. This setting is comparable to the exposure
compensation setting in cameras with automatic exposure. Enter a value between –6
(brighter) and 16 (darker). The default value is different for each lighting scheme. Exposure Value
Light level for the brightest areas of the image. Enter a value between 0 (darker highlights)
and 1 (brighter highlights). The default is 0.25. Highlights
Light level for areas of the image whose brightness lies between the highlights and the
shadows. Enter a value between 0.1 (darker mid tones) and 4 (brighter mid tones). The
default is 1. Mid Tones
Light levels for the darkest areas of the image. Enter a value between 0.1 (lighter shadows)
and 4 (darker shadows). The default is 0.2. Shadows
Intensity of colors in the rendered image. Enter a value between 0 (gray/black/white)
and 5 (more intense colors). The default is 1. Saturation
Color temperature of the light sources that should display as white in the rendered image.
This setting is similar to the White Balance setting on digital cameras.
If the rendered image looks too orange, reduce the White Point value. If the rendered
image looks too blue, increase the White Point value. White Point
If the scene is illuminated with daylight, use a value of 6500. If the scene is illuminated
with incandescent lights, match the White Point value to the color temperature of the
lights (see
Initial Color Parameters on page 1126), or start with a value of 2800 and adjust
it up or down as necessary to achieve the desired results.
