NEUTRAL DENSITY (ND)
The MOTION MOUNT provides a variable ND filter that incorporates an IR filter and polarizer. You can adjust
the ND setting using the on-screen display, or by mapping the following functions to the desired DSMC keys:
MOTION MOUNT: Increment ND
MOTION MOUNT: Decrement ND
Variable ND functionality is always enabled when the MOTION MOUNT is installed.
For more information on key mapping, go to
“Map Keys for MOTION MOUNT Settings” on page 23 .
SELECT NEUTRAL DENSITY (ND) SETTINGS
1. Select an ND value using the ND Value slider.
Alternatively, select the settings box and enter a desired value.
‒ Fraction: Displays the neutral density value as a fraction of light transmission.
‒ Density: Displays the neutral density value as an optical density value.
‒ Stop: Displays the neutral density value as a stop loss.
2. Select the desired ND Increment Size.
If you select Custom, enter the new increment size in the field next to the ND Increment Size drop-down
menu. You can select any increment in the range 0.01 to 4.00 stops.
NOTE: When an ND value over 4.00 stops is selected while in “ND Only,” the ND value on the main screen
overlay turns yellow. The following message also displays in the MOTION MOUNT menu screen: “High ND
with wide apertures may cause bokeh asymmetry”.
For more information on bokeh asymmetry, go to
“Out-of-Focus Field Modification” on page 14 .
