as my 4000 watt xenon lamp have now almost 300 hours for the
first time i can see this picture below 30 ftl (arround 27ftl)
but as this is in min. lamp power i can still go up with max. lamp
power to arround 52 ftl if i like
i try that level several times.
it looks great very nice if the source material is very good and if the movie
show all the time bright seq.
its not nice when the source switch between bright and dark seq. as it arduous to the eye.
i feel very pleasant if i runn it at arround 27 to max. 35 ftl.
more i not like but below 25 ftl its hard for me as well.
the good thing about this level is that your pupil even in dark seq.
not go up and therefore the black level looks still very nice.
thats by the way a good sample why numbers are not always tell
no instrument have a pupil that go up and down but our eye works this way
