6.6 Using long exposure times
When using long exposure times on your camera in quality, HDR, turntable or timelapse modes,
it is very important to make sure that the image is captured and saved before the VR Drive is
moving to the next position.
Here we need to differentiate between camera release with release cable or with USB cable:
Using the release cable
For example if the exposure time of the camera is 20s, it is
recommended to set the pause after to 22s. The 20s of the
exposure time plus 1 or 2 seconds for safety.
In some cameras it is possible to switch on the Noise reduction
option for long exposure times. If the exposure time of the camera
is 20s, the image capture will in reality take about 40s. In this case
the pause after needs to be set to at least 42s.
When using the release cable it is possible to use any exposure
time on your camera.

When using the release cable only, the VR Drive has no information about the camera
parameters including the exposure time. Therefore the pause after parameter needs to be
adjusted according to the exposure time defined on the camera.
Using the USB cable
• Set the “USB cable connected” to on
• Set the “Release with USB cable” to on. The VR Drive will use the
USB cable for releasing the camera instead of the release cable
• Set the “Wait camera” to on. The VR Drive will read the exposure
time used in the camera and wait for the image capture duration
before moving to the next position.
Unfortunately the noise reduction option is not readable by the VR
Drive. It is therefore not possible to use this option when releasing
the camera with USB cable only. It is then necessary to use the
release cable
When using the USB cable with compatible cameras, the VR Drive has access to the exposure
settings of the camera. It is therefore not necessary to set any pause after as long as the
following USB settings are defined.
