I have a calibration theory question. If you have two projectors of widely varying brightness levels...wouldn't they both look the same if both have their contrast and brightness properly calibrated? I know there are a million variables that will make them look different, but from a light output standpoint, what is the thought process here?

Light output is very dependent on the environment and your taste. For example you would never calibrate a high light output projector to match a projector that does not put out enough light. I personally like about 15 fL, but tastes vary. Many applications cannot get this bright because of the screen and projector chosen.

My personal tastes would be put aside in either case. I'd try to aim for the upper limit of recommendations for cinema(12-16 ftL) with the darker projector, or the minimum for video(30ftL) with the brighter projector.

I do, however, have strong personal preferences governing the next car I will buy.

So I gues the answer to my question is that both can have the contrast/brightness properly calibrated, and yet output very different ftL.

Unless you have different size screens:D They are designed for different purposes.
