FYI - * Focal Plane shutters are located close to the film plane * Kerr cells incorporate polarizers * Leaf or diaphragm shutter exposure times are calibrated with the lens wide open at 50% light level * The ability to achieve short exposure times with 35mm cameras is associated with: Focal Plane shutters * Easy interchangeability of lenses is associated with: Focal Plane shutters * The ability to synchronize with flash at all speeds is associated with: Leaf or Diaphragm shutters * Possible distortion of fast moving subjects is associated with: Focal Plane shutters * If digital cameras incorporate a mechanical shutter it is usually a: Focal Plane shutter * Malfunctioning focal plane shutters tend to produce: uneven exposure * A shutter that overexposes by 100% increases exposure over normal by: 1 EV or stop * A shutter that consistently underexposes by 100% causes the film to receive: no exposure * A .3 Neutral Density filter transmits what percentage of light incident on it?: 50% * In a given situation an automatic camera's shutter delivers a perfect exposure at f/8 and 1/1000 second but when it is used under 1/100 the amount of light present for that situation it exposes at f/8 for 1 second. The second exposure is off by about: 3 EVs or stops * The rule of thumb is that to ensure sharp photographs the exposure should not be longer than: 1/the focal length in mm * Modern focal plane shutters maintain even exposure across the film plane by: increasing slit width proportionally to the increase in curtain speed * Achieving a 100% efficient shutter leaf shutter is impossible because: it takes time to open and close the blades
