Download a light meter app for your iPhone that has a cine setting. Frame rate affects aperture setting. Better to buy a real cine light meter but they are really expensive.
Okay, cool. So which one is good? I use both a Canon 1014 XL-S and the Nikon R10 and no doubt neither's light meter is all that accurate in low light. At times the meters have been completely in the red, yet I knew we had to be at least at 1.4, or maybe even a half stop more. I took the shot and found later I was right.
How wonderful it would be to have an app on my iPod Touch or new iPhone that allowed me check against the Super8's meter.
Normally I shoot by feel. I am really not all that versed on shutter angles, etc. Here is some information on my cameras...
Shutter opening angle: 160º variable shutter; positions: 0º, 40º, 80º and 160º
150 deg or 220 deg shutter angles
I would love to have a fairly simple light meter that would allow me to use settings like those of my cameras.
