Test 2
Show Answers:

  1. Orange Gels CTO's
    Daylight to Tungston
  2. Blue Gels CTB
    Tungsten to Daylight
  3. Realist Lighting
    Creates the illusions that lighting is coming from actual light sources in the setting or location-Realistic Impact
  4. Modernist Lighting
    Little or no real life referent-emotional impact
  5. Directional Light Hard Light
    Precise beam that causes harsh shadows
  6. Diffused light (soft light)
    causes more general illumination, diffused light spreads out easy and its difficult to control. Results in soft or no shadows.
  7. Light Intensity
    • How much light falls onto an object
    • Can be read by a light meter
  8. Light Meter
    • Reads Foot candle (fc) 1 candlepower of light (called a lumen)
    • that falls on 1 square foot area located 1 foot away from the light source

    European equivalent is the lux- one luman of light on a surface of 1 square meter that is 1 meter away from the light source
  9. Baselight
    Refers to the general illumination or the overall light intensity

    • Measured by pointing light meter from the illuminated object or a scene toward the camera
    • overall light intensity
  10. Gain
    • If insufficient light even at maximum aperture (lowest f stop) you need to activate gain circuits of the camera
    • -consumer recorders do this automatically
    • -Gain will boost the weak video signal electronically if too much will produce color specks
  11. Incident Light
    What inserts the lense or what comes from a specific instrument

    Book def: light that strikes the object directly from its source. To measure incident light, point the light meter at the camera lens or into the lighting measurements
  12. Reflected Light
    • Bouncing off the lighted object
    • Meter reading gives an average of all the light being reflected from a subject (or more so the whole scene)

    Book def: light that is bounced off the illuminated object. To measure reflective light, point the light meter close to the object from the direction of the camera
  13. Contrast Ratios
    • Measure the difference btw bright and dark things/one will blackout
    • -Video Cameras record contrast ratio 30:1
    • -Film can go 100:1
  14. Video camera CCD-luminance levels
    OIRE-Black ------ 100IRE=overexposed
  15. Zebra stripes
    stripes can be set to appear around 95% IRE (or other levels) so the DP knows to use a higher f stop
  16. To decrease light you can?
    • -Move lighting instrument away from the subject
    • -Closing down the Iris
    • -Adding diffusion
  17. Trouble with overexposure is typically the result of overly high contrast ratios
    Overexpose=overly high contrast ratios
  18. Sufficient Illumination
    For colors, and objects
  19. Gain Switch
    Allows camera to shoot in lower light
  20. Attached Shadows
    • Fixed to the object surface/shape and texture helps
    • Cannot be seen separate from the object
    • Attached shadows define shape, texture (without them things look smoother)
  21. Cast Shadow
    • produced by an object and thrown onto a surface
    • can be seen independent of the object causing them
    • Ex: telephone pole
  22. Fall off
    • brightness contrast between light and shadows sides of an object
    • Indicates the degree of change from light to shadow-specifically the speed which light areas turn into shady areas
  23. Fast Fall off
    Hard directional light
  24. Slow fall off
    very gradual change from light area to shadow
  25. No fall off
    Means there is no contrast btw light and dark; all surfaces are lit evenly
  26. Special purpose spotlights and floodlights
    • Ellipsoidal spotlight-used for special effects. sharp, high intensity beam
    • Strip, or cyc, light-illuminate cycloramas (the seamless background curtain that stretches along studio or stage walls
    • Small EFP floodlight-
  27. Types of Flood lights
    • Flood lights have no lens and use large, relatively low powered lamps-highly diffused non directional
    • -Scoop-scooplike reflector, old-faishoned useful
    • -Softlight-long tubelike lamps whose light bounces off with a curved, light-diffusing reflector
    • -Flourescent Bank-row of flourescent tubes (early days of television)
    • -Portable Floodlights- produce general nondirectional illumination and cause slow falloff
  28. Beam Control of a frensel spotlight
    • To flood (spread) the beam put the lamp toward the lens
    • To spot (focus) the beam put the lamp reflector away from the lens
  29. Color
    • 3 primary light colors RGB Addictive primary colors
    • Bluish color temp higher the color temp higher the Kelvin (k)

  32. Color Temp
    • Measured in Kelvin degrees
    • Measures the relative reddishness or bluishness of white light
    • Red white light-has a low color temp
    • Blue white light has a high color temp \
  33. White Balancing
    White light is composed of equal amounts of all colors in the visible spectrum but the light sources with different color temp emit different amounts of color wave length (red, green, blue)
  34. White balancing Channels
    • If shot has to much blue reduce blue
    • If shot has to much red reduce red
    • You should white balance again every time you change lights, gels, or location
