Gamma

Adjusts the relative distribution of brightness in the midtones of an image, without adjusting the white and black points. The perceived result is to brighten and darken the areas of medium brightness in an image, while leaving the highlights and shadows untouched. This avoids a washed-out effect.

This is one of the most useful filters for correcting poor exposure in images, and should almost always be used first before trying the Brightness filter.

Tip: When opening projects created in earlier versions of Motion, previous gamma adjustments may be lost. Use the Gamma filter to reproduce the effect.

Adjust this filter using the parameter controls in the Filters Inspector:

  • Gamma: Sets the gamma correction.

  • Mix: Sets the percentage of the original image to be blended with the color-corrected image.
