The Colour-Scale effect offsets an images colours. This effect is useful in creating ambient transitions, such as from daytime to nighttime.
Use the Colour-Scale editor to set the colour scale effect by entering a value in the scale fields.
The actual colour values of the image are not changed; instead, the channels are multiplied by a selected amount. For example:
|•||If you enter a value of 1, the colour values do not change.|
|•||If you enter a value greater than 1, you increase the colour channel value closer to 255 (or white).|
|•||If you enter a value less than 1, you decrease the colour channel value closer to zero (0 or black).|
You can set the colour scale value by entering a value in the field. You can also change the values of the colour scale effect over time by attaching it to a Bezier or Ease function curve and adding keyframes.
