Luke Roberts Posted March 14, 2015 Posted March 14, 2015 Could it work without harming the camera? Let's say I'm shooting at 24 fps and then have someone carefully dial the speed to 48 fps?
Josh Gladstone Posted March 14, 2015 Posted March 14, 2015 And don't forget that you're going to have to rack the aperture open a stop simultaneously to keep the exposure correct. Or adjust the lighting simultaneously. Unless of course you want it to get a stop darker during the speed ramp.
Chris Burke Posted March 15, 2015 Posted March 15, 2015 ll in all it's pretty easy on that camera and depending upon what stock you use Aperture compensation might not be that necessary. It is if you want to have a perfectly exposeD negative - but with today's emulsions you've gotten many stops of latitude.
Luke Roberts Posted March 16, 2015 Author Posted March 16, 2015 . Why didn't you just try it? I did. It works. I don't understand the mechanisms involved, and was unsure if it would be harmful to the camera or not. ll in all it's pretty easy on that camera and depending upon what stock you use Aperture compensation might not be that necessary. It is if you want to have a perfectly exposeD negative - but with today's emulsions you've gotten many stops of latitude. I've thought about that. I'll probably have to utilize aperture method though.
Josh Gladstone Posted March 16, 2015 Posted March 16, 2015 I did a rack aperture shot on an arri s for a student film once. I had some lighting on a dimmer getting brighter while I racked the aperture closed a stop or two. Worked pretty well.
