Film appears extremely light?

Post by DocumentMqster » Wed May 02, 2012 8:11 pm

Hey everyone,
This is my first post here. I just started filming, using a Bolex B8L w/ Pan Cinor 10-30 lens. After shooting my first roll of b/w film and getting it processed, I ran it through my projector and the images appeared basically invisible. You can occaisionally make out a ghostly outline of some motion but basically the whole picture looks like white light. When I look at the film itself I can clearly see the images that I shot. I use this projector to view other films and have had no problems with the projector so Im guessing I made an error somewhere in terms of exposure? What could be the problem?
Thanks for your help!

Overexposed? Does the Fstop iris work? Can you see it actually open and close if you alter the Fstop? What FPS are you shooting at and what speed "ASA" is the film you're shooting? These old cameras were made for ASA 10,25,40 so 100 or higher can get tricky to expose correctly. You might need a Neutral Density filter to cut down the amount of light entering the lens. My other guess might be that even though you have it set at 18FPS or 24 FPS that the 50 year old camera might be only running at about 12 FPS or less. This would easily cause overexposure. I have about 5 little 8mm Bolex cameras that I got for anywhere from $15 to $50 and all of them needed to be cleaned and lubed because they ran SOOOO slow when I got them.

Thank you for your reply.
I believe that both the camera and the lens/iris are working properly. Im pretty sure I just made a mistake or used a wrong setting somewhere.
I am shooting at 16fps, at f/8, outside during the day but it was a bit overcast and not extremely sunny. The film that I used was Super Cine-X ASA 200. I also have CineChrome 100D ASA 100 for color filming but I have not used this yet. My camera has a variable shutter but I was using it completely open or only slightly shut. I can close the shutter a bit more and/or use a higher number f/stop, which is what I was going to try next but I wanted to see what you guys had to say first. Thank you.
