I own a GH2 and use full manual control in video mode. When setting up a scene I will manually dial in my preferred aperture and shutter speed and then control the exposure using a variable nd filter. This is made easier by the GH2 as it tells me on the LCD how under/over exposed the scene is based on the metering mode I have chosen.
Obviously this kind of metering does not exist on the BMPCC but we do have the IRIS button!
I will get my BMPCC in a couple of weeks time. From my understanding I can pretty much follow the above procedure for setting the correct exposure on my BMPCC, the only difference is that the BMPCC does not have a metering mode as such so it will not tell me how over or under exposed the scene is. My thoughts are that I can kind of guess what I believe to be the best exposure for the scene (after I have fixed my aperture and shutter speed) by using the variable nd filter.
To correct or confirm if my own dialled in exposure is correct I assume in theory I could then press the IRIS button on the cam to see how the BMPCC exposes the scene and see how the aperture setting differs to my setting if at all?
Not sure if this method will work? Also how does the BMPCC meter a scene?..does it do a general meter for good exposure across the scene or is it centre weighted? Also does the percentage setting on the zebras have any direct correlation to how the BMPCC then choses the correct exposure for the scene?
Any help would be much appreciated!
thanks
