•
Histogram: Displays an analysis of the object. By default, the RGB channels are selected. A
pop-up menu can be used to select Red, Green, Blue, or Alpha channels for viewing.
Click the disclosure triangles to expose the RGB, Red, Green, Blue, and Opacity parameter
groups. Click the group parameter disclosure triangles to display sliders:
•
Black In: Sets the In point for black, below which values are considered black.
•
Black Out: Sets the minimum brightness value that appears in the output. Other values are
scaled between Black Out and White Out values.
•
White In: Sets the In point for white, above which values are not output.
•
White Out: Sets the maximum brightness value that appears in the output. Other values are
scaled between Black Out and White Out values.
•
Gamma: Sets the amount of gamma correction.
•
Mix: Sets the percentage of the original image to be blended with the color-corrected image.
Negative
Inverts color and brightness in an image. This filter can be used to turn a scanned negative
image into a positive.

Parameters in the Inspector
•
Mix: Sets the percentage of the original image to be blended with the color-corrected image.
OpenEXR Tone Map
Applies tone mapping to an OpenEXR image, reducing the dynamic range of the image so that
it can be viewed on your monitor. The Exposure, Defog, Knee Low, and Knee High parameters
allow you to control how the pixels in the high-dynamic range image are mapped to a lower
dynamic range.
Tip: A recommended workflow is to apply the OpenEXR Tone Map filter to the result of your
composite. In other words, apply the OpenEXR Tone Map filter after you have applied other filters
to the OpenEXR image or blended the image with other images in your project.
Note: An OpenEXR file imported into Motion 5.0.2 or later is maintained as a high-dynamic
range image and will appear brighter than in earlier versions of Motion (until you specifically
alter the image). Prior to version 5.0.2, Motion forced tone mapping on imported OpenEXR
images. In Motion 5.0.2 or later, when you open an older project containing an OpenEXR image,
an OpenEXR Tone Map filter is automatically applied to the image so that the project retains its
original appearance.
Tip: To maintain the full dynamic range of an image being exported as an OpenEXR file, disable
the OpenEXR Tone Map filter prior to exporting.
