3.4.4 Important remarks concerning correction values
The SIXTOMAT F2 is a precision meter calibrated with great accuracy to provide exact exposure
data. Should you still not be satisfied with the results, then you should remember that there are
independent variables that can influence the success of your exposures.
For example:
the „true“ sensitivity of the sensor or film may differ from the one listed
the „true“ shutter speeds and f-stops of your camera may deviate from the rated values
Deviances may develop during film development or RAW data processing.
Additionally, there is the purely subjective matter of personal taste when evaluating finished pictures.
However, you can attune your SIXTOMAT F2 to the special characteristics of your camera and
workflow.
We recommend the following method:
Measure several normal motifs according to the light metering and object metering methods and take five
exposures each. The first exposure must be lit with the exposure data indicated by the SIXTOMAT F2
then increase and decrease the exposure data for each following exposure by ½ step and then a full
step. The exposure conditions you note must not change during any of these exposures. Now select the
optimum exposures from these pictures according to your requirements and compare their exposure
values with the metered values. Should you discover that you prefer pictures taken with changed values,
you can program these values into your SIXTOMAT F2. The SIXTOMAT F2 now calculates precise
exposure data resulting in optimum pictures while also taking the characteristics of your workflow into
consideration.
