In-Depth Information
In the case of most video, noise is stored in the blue channel.
To see the various color channels separately, click the lengthily-
named Show Channel and Color Management Settings drop
down at the bottom of the Composition panel. Its icon looks like
a little Venn diagram, with three interlocking circles (Fig. 4.23).
From the Show Channel and Color Management Settings drop
down, I'm going to change the value from RGB (which is the
default composite view of all color channels with alpha) to Green.
This will show us a visual readout of the green light used to make
this image. I'm going to also zoom in to about 800% so that we
can get a better look at the noise and compression artifacts in this
channel (Fig. 4.24 ).
The green channel looks pretty clean. Now let's change the
view to the blue channel and see the difference (Fig. 4.25).

options here, in the Show Channel
