E. Shutter, Shutter Speed and Shutter Angle
E3. ECS Shutter
The ECS Shutter is useful for shooting computer displays
or devices where it is necessary to finely tune the shutter
speed to match a particular frequency. For example,
when shooting a computer monitor you may see a dark
band rolling down the computer screen. By adjusting the
shutter speed while pointing the camera at the computer
screen and using the ECS function it is normally possible
to eliminate or minimize these dark bands. Do note,
however, that in an office environment where there may
be multiple computer screens you may only be able to
synchronize the shutter with one monitor at a time.
E4. Auto shutter
The shutter speed will be set automatically by the
camera's auto exposure system to provide the optimum
exposure level. It is recommended that this should
only be used when other forms of exposure control are
unavailable.
