4.3 … control the exposure (continued)
4.3.5 Some examples
In certain situations full sensitivity – so full TDI Stages – are required and a fast 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 which in turn
requires to reduce TDI Stages.
Here are some examples:
Moving landscapes
TDI Stages: 10x
Exposure: 1/200
ISO/ASA: 100
f=11, 120°
Lens: 80mm
Schneider Apo Dig L
Time for scan: 1.5 s
To freeze the motion of the waterfall, it is necessary to reduce TDI Stages to 5x or
10x.
