ABSTRACT
With any HD camera my approach is the same but the technique a little different. I set the 18 per cent gray card up as before and, close by, set up a carefully lined up decent sized monitor, preferably a 24-inch monitor. Making sure that the card is evenly lit, I adjust the exposure until the gray on the monitor exactly matches the gray of the card with a 24-inch monitor they will even be roughly the same size if they nearly fill the screen. Now I take a reading of the card with a digital spotmeter and set the reading in the viewfinder on its scale, I then adjust the ASA setting on the meter until the aperture shown is the same as that on the lens. The ASA setting on the meter is now showing the equivalent ASA speed of the camera. With the majority of HDCAM cameras this works out at around 320 or 400 ASA though as development continues I am finding cameras, sensitivity to be increasing so never assume, always check.
