more easily. Sometimes, subtle color changes are diffi cult to dis-

Beluga whales are white, but you couldn't really tell from this
image. It is too dark, as it has acquired an aqua-colored tint from
the water and glass. Apply the Auto Color effect to the top layer,

and after (right) images (Fig. 6.2).

means that each frame is processed independently. It also means
that the changing composition of the shot might cause the auto
effects to produce wildly different results from frame to frame.
The Temporal Smoothing setting determines the time (how many
seconds) that the effect will need to smooth the results. So, if this
value is at 1, the Auto Color effect will look at one second's worth
