Hey people. I know it's a topic that's done to death but there's just so much information out there that it's easy to get lost in it so I'd like some other peoples opinions.
I've been shooting on a Bolex EBM (converted to S16) for a little while and have been getting "okay" results. Having a background in 35mm still photography was helpful but it's taking me a while to understand fully how to set the camera/lens up to expose the film correctly. And judging by other peoples footage on youtube, it's something a lot of people don't fully understand.
I have been working with the following factors which I pulled from an old Bolex manual (feel free to jump in and correct me, as it may help with the inconsistencies I get in my footage):
The shutter angle is fixed at 170 degrees.
At 24 fps, this gives me 1/50th exposure time but because of light lost through the viewfinder mechanism, its more like 1/67th.
So I would get my light meter out, set the ISO at 200, set the shutter speed at the closest speed (on this one it's T = 60) and take a measurement. Say it would give me an F of 2.8. I'd set the aperture on the lens and start filming.
For the most part this worked out okay, especially in well lit conditions. However, for any other condition it was very variable.
Am I doing this correctly? Is there anything different I should be doing?
And once I start getting measurements outside of my set ups capabilities (I only have an Angenieux 12-120 lens right now) is it just a matter of moving to a higher / lower speed film, higher speed lenses, incorporating ND filters, etc?
Anyway, thank you for reading this - feel free to contribute anything you like. I'm sure other beginners would appreciate it as much as I would.
