I had a problem with a shoot with the F-950. I rated the camera at ASA 125 using the PRO 35 adaptor since you lose 1 1/3 a stop with the adaptor(setting my lens opening at F/2.0). I was shooting on blue chroma and getting the same f-stop reading in my incident light meter on my (person)subject and blue chroma. I usually underexpose my chroma by half a stop but in this case I thought that the blue was good enough.
My HD technician was saying that my chroma was somewhere between 20-30 IRE and she thought that it was a bit low for a blue chroma. I checked the waveform and saw it but I didnt know what IRE the blue should be on. My talent(sublject) was pretty ok hitting 60-70IRE on the waveform. So I told her that I think I have to trust my meter since I wouldnt want light the blue screen stronger than my subject.
Anyway Im sorry if i missed some threads on this.
