Bryce Fortner Posted March 15, 2007 Share Posted March 15, 2007 Hello, I'm shooting some stop motion tomorrow on an older Eclair ACL. The camera's motor has been modified for stop motion and holds one frame for 3/8 of a second. I've been trying to do the math in my head, but was curious if anyone here had an idea of how I should compensate my meter to get the proper exposure... I appreciate any advice. Thanks!

Premium Member Michael Nash Posted March 15, 2007 Premium Member Share Posted March 15, 2007 If my math is right that's equivalent to 1.33 fps. Set your meter to 1fps and close down 1/3 stop, or else find an ASA & frame rate combination that gives you that number. But this is only theory -- test!

Bryce Fortner Posted March 15, 2007 Author Share Posted March 15, 2007 I figured it would be about 5 stops down from 24fps... so that seems right. Thanks for the help! Link to comment Share on other sites More sharing options...

Hi, I would go with 1 FPS or 1/2 second exposure if your meter does not read in FPS. Reciprocity factor starts to rear it's head so slight overexposure is a good thing.

Been shooting overnights... :blink: Link to comment Share on other sites More sharing options...
