When the VR Drive light meter sensor is connected to the VR Drive, and the camera is compatible
with VR Drive USB control, it is possible to use the VR Drive in a fully automatic way. This option is
only available for “Quality” and “HDR” modes
The VR Drive is able to measure the light before starting the image taking. Then, according to the
selected strategy and options, the VR Drive will set the correct exposure time, ISO/ASA and aperture
on the camera. The image taking process will then start automatically.
This way there is no need to adjust manually the exposure time on the camera or change the HDR
reference exposure time before every project. The image taking process is now fully automatic.
