Hey Guys!
I've been wondering about this candela measuringthing... how come we measure candela (or foot candles) when we talk about exposure? Talking about contrasts, I understand the good thing about measuring candela, but not with exposure.
The Luminance is the unit you describe how much light passes through an aperture. The candela does only describes how much light there is in a specific place and direction. But because a lens is always stealing some light, the candela can't be the right unit for this purpose...
Therefore, you should check the candela, when dealing with contrasts and the Luminance, when dealing with exposure.
Or have I got it all wrong? I've heard that the science behind exposure is one of the hardest things to understand when it gets to filming so maybe that's the reason I don't understand :P
Thank you for your response!
