All,
I measured the light hitting my potential screen position with my windows open (measured in direction of proposed projector position) and get a consistent 5 lux.
5 lux = .46 footcandles
5 lux = .47 footlamberts
My proposed usage is an Epson 3050 from 11.5ft onto 100" diagonal.
Using the Projector Central calculator and a 1.0 gain screen shows an image brightness of 30 foot lamberts.
If ambient light occurs from the side, shouldn't the vast majority of the light just 'skip' off (angle of incidence = angle of reflection ...) ?
I always try to over analyze things and really need to fully understand ambient light and measurements.
What measurements etc. can I take to better quantify my living room as a projector/screen location?
Thanks in advance,
AJ
