performed) of the entire overhead to determine
nonfunctioning instruments. If time allows, examine
the softpatch for errors to reduce the number of
possible explanations for inoperable instruments.
Although the instruments in overhead electrics are
realistically focused in sequential order, the focus for
each system in the Hokey light plot will continue to
be individually illustrated. The overhead frontlight
focus will be examined first.
Overhead Frontlight Focus
The overhead frontlight washes may be a continu-
ation of the frontlight system originating from the
front of house. In this case, the two frontlight washes
for Hokey consist of three zones each. The first zone
was hung on the front of house truss. The next two
zones are hung on the first and second electrics.
Figure 12.23 shows channels 6 > 10, the instru-
ments on the first and second electric, colored in
Roscolux 33. When focused, they’ll act as the sec-
ond and third zone in the pink straight frontlight
system for Hokey. The apron spike marks, along
with the front zone 2 and 3 centerline spike marks,
provide the triangulation for the focus points. The
masking leg spike marks will provide signposts for
side shutter cuts if the legs aren’t in place during the
focus session, while the upstage T’s (the light line)
provide the signposts for top cuts if the scenic stack
is absent. This focus will be duplicated for chan-
nels 16 > 20, the Lee 161 blue straight frontlight
wash. The first instrument that will be focused is
1 electric unit #9, which will be focused on center-
line. This unit will be focused first to ensure that
the upstage frontlight will be focused symmetrically
side-to-side.
Figure 12.24 shows the focus chart for unit #9
on the first electric. The preliminary focus point is on
centerline, 10-0 upstage of plaster line. The beam
is intended to remain open, except for a possible top
shutter cut off of the #1 black border upstage of the
electric, or the black scrim in the scenic stack.
The placement of the second zone of focus
points should be double-checked before the focus of
the entire first electric frontlight system has begun.
This is accomplished by standing on the center-
line focus point in the second zone, and activating
the center channel of the first zone of frontlight. In
this case, that would be unit #6 on the truss, con-
trolled by channel 3. If the light from channel 3 is
hitting the lighting designer above eye level, the first
