Description

L = 1852 x 1,5 sec und 1350 x 2,0 sec
R = 746 x 2,8 sec
G = 432 x 2,0 sec
B = 555 x 2,5 sec

Die Daten sind aus dem Sommer 2017, aber erst jetzt habe ich sie ordentlich bearbeiten können.
Die Luminanz wurde einmal mit dem Reducer aufgenommen (1,5 s) und einmal ohne (2 s), die Farben jeweils mit.

The dates are from summer 2017, but only now I have been able to edit them properly.
The luminance was captured once with the reducer (1.5 seconds) and once without (2 seconds), the colors with.
