SLIDE 5
F-stop: conceptual foundation of exposure Aperture: opening in LENS that allows light through · created by iris blades/leafs · measured in F-stops*
F-stop Scale
353#01&&&&&slide&4&
* F-stop is calculation (ratio) of lens allowing light through T-stop is measured (taking into account of transmittance) of light passing through lens

SLIDE 6
Field of View (F.O.V.): perceived frame size Focal Length: lens to sensor convergence distance · “lens size” measured in millimeters Sensor: digital image acquisition size “footprint” Gate: film exposure size “footprint” Normal: cinematic perception of human eyesight
