Canon 814 timelapse-Shutter Speeds

[cyclops39]

HI:
I still havnt figured out what the shutter speeds are on my 814 Canon. It is just the plain ole 814. For instance my Bolex 16mm at the single frame is 1\30 of a second and at 24 FPS it is 1\60th. My Canons light meter is not working so i would have to use my light meter. Also does any body have a Interval timer for a Canon to sell or know how to make one.THANKS

The first idea may not work on your camera if you do not have an intervalometer.

If your camera has an "intervalometer" function on it, (a.k.a. time-lapse function), the shutter speed while filming time-lapse can usually be changed as you change the filming speed knob from 18 to 24 to slo-mo....

.....even though the camera is in time-lapse mode and running one frame at a time in increments of every few seconds, the shutter speed can still be affected on some cameras by changing the separate film speed knob,....

So, it now becomes a simple task to open the film chamber door and "listen" (it is easier to hear the shutter operate with no film in the chamber) to the shutter for a change in pitch when you change the filming speed knob while still in the time-lapse mode.

If, however, you do not have an intervalometer button on your camera and the single frame position is on the same dial as the 18-24 switch, then you can not do the above test.

However, the other test you can do is to take a flash light, put it on a fast moving turntable, anywhere but in the center of the turntable...then put the camera overhead and film the the flashlight as it orbits the center of the turntable...when you get the film back, you can determine the changes in shutter speed by the amount of blur the flashlight generated at different filming speeds.

The camera frame should capture the complete revolution of the flashlight for this to work, and the turntable must move a constant speed, not crystal sync accurate, but it needs to be a steady speed for the filming tests to have any validity.
