Bolex H-16 Reflex 16mm camera
The Film Camera Bolex H-16 Reflex 16mm camera

An Overview of the Camera
The Lens The Lens Mount The Viewfinder The Film Chamber The Motor The Film gate and claw The Shutter
6
Exposure Exposure is determined by intensity of light that pass through the lens and the time each frame is exposed to the light. Exposure = Intensity X Time It is controlled by aperture(T-stop) and (camera speed)Frame-rate Other factures that play a role in determining exposure are: Film speed, Lighting, Filter, Shutter Angle
7
Aperture The intensity of the light is controlled by aperture. The aperture of the camera is like the iris of the eye.
8
Film Speed A fast stock or high film speed refers to a film’s sensitivity to light. The higher the film speed, the more sensitive it is to light. ASA number Typical film speed: 50D -100T and below: Slow 200T-320T: Medium 500T-800T: Fast
9
Camera Speed of Film Rate
Standard Speed: 24fps Slow motion: speed faster than 24fps Fast motion: Undercranking: speed slower than 24fps Time-lapse: With significantly slower speeds, time is proportionally sped up. Animation.
10
The Variable Shutter Narrowing the angle reduces the exposure time.
Exposure time (shutter speed): 1/50second in 180˚shutter angle. For achieving the selected f-stops or depth of field In-camera fades and dissolves
11
Motion Picture Film Characteristics
Film Size: 65mm: Optimum image quality and effects works 35mm: Theatrical release and broadcast television 16mm: Transfer to video for broadcast television and student filmmaking 8mm: Student filmmaking and special looks
12
Aspect Ratio 1.33 :1- academy or standard (4:3)
1.66:1- European widescreen 1.85:1- American widescreen (16:9) 2.35:1- Anamorphic projected image (Super 35mm)
13
Light Measurements Incident light meters measure the intensity of illumination coming from the lamp and express the reading in f-stops, based on the film speed and camera speed or shutter speed input. Reflected light meters measure the light reflected from the subject and yield a reading in lumens per square foot
