4.3.3 Using the exposure speed to control the exposure
The minimum exposure speed is dependent on TDI Stages:
TDI
Stages
Minimum
exposure speed
(seconds)
1x 0.0005 1 / 2'000
2.5x 0.0013 1 / 800
5x 0.0025 1 / 400
10x 0.0050 1 / 200
20x 0.0100 1 / 100
In certain situations full sensitivity – so full TDI Stages – are required and the minimum
exposure speed is less relevant. In other situations, for example in action photography
(sports or moving landscapes), it is important to work with a faster exposure speed. This
is achieved by reducing TDI Stages.
4.3.4 Using the aperture to control the exposure
As for any camera the exposure of the Roundshot D3 camera can be controlled by
opening or closing the aperture. This is done manually on the lens. For best results in
sharpness and depth of field we recommend closing the aperture as much as possible.
