available only to the current session. You can also save grades to
the Memories (the lettered thumbnails) with Option-# (where
the # is the number 1-9, for A-I) and recall the Memories with
Command-# (where the # is the number 1-9).
In the Gallery Screen, you can save and transfer Stills, Memories,
and PowerGrades.
3. With your grade saved as a PowerGrade, go to the Session menu
and choose Base Memory Reset. You'll notice in the node graph
that your secondary nodes are gone and that your primary node
has been reset.
Many colorists grade images while they're still, but grading while
looking at a moving image is beneficial. The keyboard shortcut for Play
is the period key. The keyboard shortcut for Stop is the spacebar. The
keyboard shortcut to toggle looping is Command-L.
4. To create the basic bleach bypass, we'll create two nodes blended
together as layers. The first node will have some funky color
alteration that cross-processed chemical looks tend to have. I
borrowed this color curve look from a tutorial I saw in Layers
Magazine. Go into the Custom Curves tab and right-click under
the Curves (near the reset buttons) to get a contextual menu;
uncheck “Gang Custom Curves,” which is on by default. Then
click and drag on points on the graphs to make them look like
Figure 12.31 . Note that the luma, red, and green curves all have
the bottom point pulled down and the top point pulled up and
that the blue graph is the reverse. Also, because this image has so
much green in it anyway, I didn't pull up the top green point as
much and I pulled the bottom point down more. But that's just
for this image with more green to it. If you want, you can really
do this part much more subtly than I did it.
5. A real bleach bypass or skip bleach effect is done by process-
ing film and skipping the bleach bath that is typically used in
the normal processing of the film. Sometimes, instead of com-
pletely skipping it, the film is just left in the bath for less than
the recommended time. The lack of bleach means that the silver
in the film is retained. The effect of this is basically a contrast-
ier, grainier image, because the layers of colored emulsion also
have a layer of silver. To create this effect, we're going to cre-
ate a contrasty black and white and layer it on our weird color
node. Press Shift-P to create a parallel node. The bottom node
should already be selected, so just pull saturation all the way
down.
