In effect, the guillotine shutter leads to a higher fidelity reproduction of what is being filmed for both the viewer in presentations and the camera operator on location.Most of the original batteries in these cameras left are dead.
As this is shorter than in most other Super 8 cameras, the shorter exposure time gives the impression of producing sharper pictures: motions do look more accentuated and static shots much crisper. Due to the required timing of the alternating phases of the guillotine shutter, the maximum exposure time at 24 fps is 1 /86 sec ( 1 /87 sec for 25 fps). Beaulieu's unique patent solution is a typically French invention: a guillotine (up and down) shutter with a 45° mirror that – as Beaulieu brochures proclaim like a mantra – lets alternatingly 100% light onto the film and 100% light into the viewfinder.
Obviously, that approach somewhat compromises both usages, especially under bad light conditions. Normally, Super 8 cameras use a beamsplitter or prism of varying optical quality that diverts 75% of the incoming light onto the film and 25% into the viewfinder. If the camera is off a bit, you could just adjust the ASA/ISO knob to compensate to 'lighten' up your images.Īlso found this in a white paper written by Lehnertīeaulieu is known for being the only manufacturer to incorporate mirror reflex shutter systems in Super 8 cameras. To double check, compare the camera's metering to an accurate light meter and meter several objects light and dark as well as an 18% gray reflection card. As long as the camera's exposure metering system is working correctly, and you have set the film speed on the ASA/ISO knob correctly, the exposure should be fine. However, this comes at a price for these cameras not really being useful for very low light conditions (unless you film at a very slow frame rate, allow a longer shutter time duration per frame.best done on their silent models or the NIZO or BAUER cameras with their special options for longer exposure per frame).Īs for your footage being darker, that shouldn't be the case just because of the shorter exposure per frame, unless you're filming in a light level too low for the film to record. BEAULIEU cameras have been known for very sharp images, due to their frame registration/transport, significantly higher shutter speed per frame due to their shutter design, and those terrific lenses.
Filming and projecting/transferring at 24fps offers only a slight quality improvement, is harder on the film itself, eats up film faster at 2.5 minutes per cartridge versus 3min 20 sec at 18fps.Ī smaller shutter angle, either due to increased filming rate of actual shutter angle, will allow less motion blur per frame this can be helpful or visually disturbing either way, depending on what is being filmed and how you want the 'look' to be. Unless I need to smooth out some motion movement, I only film with Super 8mm at the original design intention of 18fps, which is fine. Typically anywhere from 1/20th to 1/40th of a second per frame, depending on if you're shooting at either 18fps or 24fps.

Those truly allow nearly a full stop of more light to expose each frame. Among those, the pie/wedge slice opening is much larger than the normal range of 130 to 180 degree range.and is anywhere from 190 to 230 degree opening, depending on the make of camera. So, yes, in lets in more light.but a true XL (existing low light) camera it isn't, compared to other XL Super 8mm cameras. In the LL setting, the did a modification on their shutter to allow a bit more light to enter, albeit some limitations for use as per the Instruction Manual's details, NO fading allowed at this setting! In the circular shutter design, the shutter speed per frame is determined by the 'pie' slice wedge opening angle as well as the rotation speed (frames per second).on the BEAULIEU, the math just works out in their design to be 1/96th per second, as that is their standard setting.
BEAULIEU 6008 S MOVIE
The 1/96th of a second shutter speed is considered "normal" on the BEAULIEU 6008S due to the design of the oscillating guillotine shutter.which moves up and down, rather than of a circular design as are most movie camera shutters.
