3.1.1 Shoot settings (continued)
To capture static or almost static scenes where a fast exposure speed is
not important, close the aperture (for example, from f=8 to f=16). This
will increase sharpness and depth of field.
The larger the scan area of the sensor (the more TDI Stages) the steeper
the angles and therefore the more critical the sharpness, especially for
wide-angle lenses. Therefore it is advisable to start with smaller TDI
Stages (for example TDI 5x) and increase TDI Stages only when
necessary.
The exposure speed is dependent on the selected sensitivity (TDI Stages).
When changing TDI Stages the exposure speeds will be changed
accordingly. For more information on exposure speeds please refer to
section 4 „How to“.
TDI: select the TDI level. A higher TDI means that a larger surface of the sensor is
used for the scan. More pixels will be exposed simultaneously with higher TDI,
making the entire scan process faster. Using higher TDI can be an advantage when
working under low-light conditions (indoor).
ISO/ASA: select the ISO/ASA level to be used. Increasing the ISO level will increase
the sensor sensitivity but also noise level. It is recommended to use the lowest ISO
level possible for better image quality
Exp. Corr.: the exposure correction is used to fine tune the exposure speed. It is
possible to select sub-f-stop adjustment for perfect image exposition (0.1f-stop)
Timer: defines the delay time before starting the scan
