When operating at 23.98 or 24.00fps, these equal common shutter angles of:
When operating in Relative mode, the Shutter Speed values are proportionately reduced or extended to
correspond to changes in the instantaneous capture frame rate.
This mode is analogous to use of a fixed shutter angle on a mechanically shuttered camera.
E.g. Enabling Relative mode with 1/48
th
sec shutter at 24fps will mean 1/96
th
sec for 48fps, and 1/16
th
sec
for 8fps. This achieves the same visual result as setting a180 degree shutter.
NOTE: Prior to recording in Timelapse with extended exposure times (1/ 3 rd sec or longer) it is
recommended that a fresh Black Shading routine is performed. Ensure the camera is set up in
Timelapse at the desired exposure time, then press SYSTEM > SETUP > MAINTENANCE > BLACK
SHADING to perform a Black Shading calibration. After recording Timelapse at extended exposure
times, perform a Black Shading calibration again when you revert to shorter exposure times (1/ 4 th
sec or shorter) either in Timelapse, Normal or Varispeed modes.
SYNCRO
When operating in this mode, the Shutter Speed values may be proportionately reduced or extended to
tune exposure time to a precise value. Range 10–90. Default is 50. To adjust: Select SYNCRO and twist
joystick to change the highlighted SPEED ADJUST box to the desired setting.
E.g. Setting Syncro to 53 with a 1/60
th
sec shutter is equal to 1/56.6 sec exposure time.
PHASE
Provides a delay relative to the start of the frame for the exposure time. Phase may be adjusted over the
range - 45 to + 45 degrees. Default value is 0. To adjust: Select PHASE and twist joystick to change the
highlighted PHASE ADJUST box to the desired setting.
