Shooting a student project on the Bolex H-16 camera, I understand that 25% of light is lost by going into the viewfinder. That means that on a normal light meter it has to be compensated for right? I will be using 250D stock, would setting the ASA on the light meter to 160 compensate for this?  and then could I use the light meter as normal?

 

Also is there any common problems or tips and tricks that might be useful for me to know before the shoot?

 

Thanks

Will

Either set ISO to 160 and use shutter speed 1/50 or set ISO to 250 and use shutter speed 1/80. Both ways are good and will give the proper exposure (for 24fps, that is).

It's not quite 25% - measurements on 2 models indicated more like 16~18%  (I can't remember exactly but it was an even number in the teens at least)

 

But why trust me, I'm just another guy on the internet ;)  ... maybe I measured incorrectly twice  ...aaaaand anyway, 25% seems to work just fine.
