Modifying Image Contrast

Primary Colour Grading > Logarithmic Mode: Improving Contrast >

Improve image contrast by modifying the film gamma with the Contrast slider. Use the Contrast Balance wheel to increase the contrast of any channel while decreasing the contrast of other channels. These changes in contrast are relative to the pivot point.

NoteTo see how balancing the contrast works, view the histogram. Press Alt+2 while modifying the contrast balance and the pivot point.

WarningThe Histogram, Waveform, and Vectorscope functions do not update when GPU processing is enabled.

To improve image contrast:

Indicate whether this is the initial or final primary grade:
- To work on the initial primary colour grade, click Input.
- To make final adjustments to the primary colour grade, click Output.
Modify the contrast:
- To increase the contrast in the image, drag the Contrast slider up.
- To decrease the contrast in the image, drag the Contrast slider down.
To increase contrast in a range of colour in the image, enable Contrast and then drag the Contrast Balance wheel towards the colour.

The colour you drag toward increases in contrast while the opposing colours decrease in contrast. The overall image contrast remains the same.

NoteThe pivot point is the point around which the contrast balanced. See Setting the Pivot Point.
Make adjustments to the image using the Contrast slider and Contrast Balance wheel until you are satisfied with the results.
