Stop Motion - Exposure Compensation


Bryce Fortner

Recommended Posts

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!

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!

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.

Yes, of course I meant open up one third from 1fps, not close down. Been shooting overnights... :blink:
