Hi. I was wondering when I take my light meter reading, what shutter speed should I adjust to when I'm filming at 24 fps? I don't know if it matters or not, but I'm filming with an Eclair ACL2.

Obviously, I'm new to filming. I was wondering if anybody could suggest an easy to read, comprehensive book on the basics of how to shoot on 16mm. Thanks!

as in stills shutter speed ? I'm not sure of the shutter angle on your Eclair but if you can get that info the answer is simply:

(shutter angle/360)*(1/fps)

for example if the shutter angle were 180deg and you are shooting at 24fps:

180/360 * 1/24 = 1/48th of a second

The ACL shutter is 175 degrees. 175/360 x 1/24 = 1/49.44 (round up to 1/50 of a second)

What kind of light meter are you using Jimmy? Some allow you to change the shutter angle and will allow you to adjust for different frame rates.

And as far as books. The Filmmakers Handbook was the main text book when I was in school. You can get it for about $15 on amazon. It has pretty much everything you'll need.

HI, just wanted to ad something. In case your camera happens to be a S16 with a 144degree shutter your shutter speed would be 1/60 sec. 144/360x24 =1/60.
Cheers, Bernie o
