[rollei_list] Re: Question about Rollei Filters and compensation

Patric, I was measuring the light this afternoon with
my Cds cell lightmeter looking the sky, without filter
the reading was "15", with the light red it was
13/12.8, it means -2 stops, with the orange filter was
14, it means -1 stop and with yellow the reading was
14.5, it means 1/2 stop, and then I was right in my
original post on the topic, at least I was right
regarding my lightmeter and filters.
I remember this photo that I took with the light red
filter, exposure measured putting the light red filter
on the Cds cell:

All the best
