Gain and ND Filter
If you're shooting in a dark area where there is not enough light for the camera, you can increase the
exposure level by raising the gain.
Gain settings:
• Low <L> 0 dB - this is the normal position when the gain is turned off
• Medium <M>- raises the gain of the camera by 6 dB, or one f-stop
• High <H> - raises the gain of the camera by 15 dB, or 2.5 f-stops
Note that shooting with the gain on will increase the amount of noise and result in a picture with more
grain. If possible, add more light to the scene and avoid using gain to get the cleanest image.
ND Filter:
If you're shooting outside in sunlight, you may notice that it is difficult to turn the iris down enough get
good exposure. If this happens, use the ND FILTER switch on the side of the lens. This will filter out
some of the light entering the lens before it hits the iris,
without changing the color. Normally, the iris should
not be set higher than f8; if it is, use the ND filter.
• 1/4: Intensity of light is cut down 2 f-stops
• 1/16: Intensity of light is cut down 4 f-stops
• 1/64: Intensity of light is cut down 6 f-stops
NEVER USE THE ND FILTER INDOORS!
