Random semi-related question…
In the ceiling bounce test, concerning ambient light, I have to ponder…. if a lamp is on in the room and there is a very slight reading on the meter, does the 1200 lumen light hit the ceiling and add to the 2 lux already on the meter? If you’re running the test and have someone turn off the lamp, does the meter reading change?
If it’s daylight outside but the blinds are closed such that there is a low level of ambient, does that actually influence the meter’s total reading when the light is turned on? Can you add 3 lux of ambient to 135 lux produced by the flashlight and get a measurable gain? What about adding 3 lux of ambient to a flashlights 665,000?
So, at what point does a bit of low level ambient light actually matter? I mean, I know some people that do their lux tests in a blacked out basement, as if it really matters. Just wondering is all.
I’d test my GT mini compared to one of my D1S’s but of course, all are modified so it wouldn’t be an exact comparison. Wonder if I could swap reflectors in one of em and see a difference? Hmmmmm……
