F. Changing Shutter B!4des
Fb. #rr3
Two, three and five bladed shutters can be mounted
on the shutter pulley. The mounting holes used to
secure the blades to the pulley allow a srnall adjust-
ment for shutter blade timinp. Incorrect shutter
timing results in what is commonly called "ttavel
ghost". The adjustment is accomplished using the
SMPTE test film and adjusting the blade posirion
for minimum upper or lower image movement as
shown in {Fig. #43}. Since the adiusting scre$'s
are only accessible with the cam tank removed,
thil become s avial and error adiu*tment. Ho*ever,
the skilled technicians can ascornplish this in one
or t\ro adjustments-
When mounting the 2 blade shutter, the missing
semi circle on ths hub must be positioned toward
one of the blader. The curved edge of the blade
faces away from the cam tank {See Fig. #44,
