Dear All,
I have been wondering and testing how light stacks and its correlation to light fall off. The term 'stack' is most likely wrong, what I mean by it is when two beams of light overlap does the luminance value say foot candles in this instance add up? It makes sense as for example a maxi brute or other Fays that have several lower wattage lamps such as 1k's or 650's add up to produce a larger output. So for instance if I had several Par64 cans and rigged them in an array in which the distance between fixtures was minimal the total output would be the addition of all the outputs of the par cans combined?
However I question this further (reference diagram bellow) in which then if you bounced several sources into the same area of say a frame of ultrabounce. If the beams overlapped would they add together create a more powerful source with therefore less fall off. Putting terms into words is not my strong suit so I have drawn a crude diagram bellow. The tests I have created had mixed results and while practical is good and something I shall test further for a future rig the theory behind it interests me greatly!
Please do note nothing on this diagram is accurate from the refraction etc to anything. Just a crude idea.
