Contrast can be measured with the DIGISKY by using the f-stop

measured.
The first measured value appears in the digital display. It remains
for the duration of the entire measurement as a reference value
(e.g. gray card measurement). The momentary measured value
is indicated on the analog scale. After releasing the M key, the
measured subject contrast appears on the analog scale. Subject
contrast is indicated in light values as dEV.
The average, minimum and maximum values can be displayed one after the other by
