4Light, Color, LightingTypes of LightDirectionalDiffused
5Light, Color, Lighting Directional Light Direct Precise Hard Shadows Used to light specific areasExamples – Sun, Flashlight, Car Headlights, Studio spotlights
6Light, Color, Lighting Diffused Light General Not Precise Spreads Seems to come from all directionsUsed to light large areasExamples – Fluorescent lights, Classroom, Studio Fill lights (large round lights)
7Light, Color, Lighting Light Intensity Amount of light that falls on a given area.Measurement – Lux (European Term); Footcandles (American Term)Baselight – refers to overall light intensity.Low Baselight – open iris to allow more light into camera.High Baselight – close down iris to allow less light into camera.
8Light, Color, Lighting Baselight Example Holiday Choir Concert – iris on Auto and picture washed out. Iris set at 2.8 +/-Holiday Band/Strings Concert – iris on Manual and iris adjusted to 5.8 to 7 for quality picture.
9Light, Color, Lighting Shadows Attached Falloff Usually unaware of shadowsTwo TypesAttachedFalloff
10Changing the Field of View Move the camera closer to event.Change the focal length by zooming In or Out.
11Light, Color, Lighting Attached Shadows Tied to object Help us define the basic form or an objectContribute to texture
15Light, Color, Lighting Cast Shadows Seen Independent of the object. Hand shadows on wallHand not seen – shadow seen
16Light, Color, Lighting Cast Shadows Help tell us where things are and when events take place.Examples – Shadows of utility poles, traffic signs, building walls. Pg. 123Note: Even if Cast Shadows touch the base of the object they remain Cast Shadows NOT Attached Shadows
17Light, Color, Lighting Falloff Indicates the degree of change from light to shadow.The ‘speed’ with which light area turns into shadow area – the brightness contrast between the light and shadow sides of an object.
18Light, Color, Lighting Fast Falloff Slow Falloff Change from light to dense shadow is extremely abrupt.High Contrast between areas.Slow FalloffGradual change from light to shadow.Subtle Contrast between areas.
19Light, Color, Lighting Falloff Defines the contrast between light and dark areas and how quickly light turns into shadow.
20Light, Color, Lighting Color Basic Process of Color Mixing TV Receiver and generated colorsColor Temperature and Mixing
21Light, Color, Lighting Primary Light Colors Video Camera Beam Splitter takes White light and creates:RedGreenBlue
24Light, Color, Lighting TV Receiver Works on color mixing principle 3 Electron guns in neck of tubeOne gun fire beams of light at Red, another at Green, etc.More intense the beam the more the dots of color light up.Mixing color.
26Light, Color, Lighting White Balance Not all light sources produce light of the same Whiteness.Examples – candle (reddish); fluorescent (bluish); flashlight ( weak batteries bluish, strong batteries whiter)
27Light, Color, Lighting Color Temperature Kelvin Degrees Standard by which we measure the relative reddishness or bluishness of white light.Kelvin DegreesMeasures the color differences of white light.
28Light, Color, Lighting Kelvin Degrees More Bluish the white light – the higher the color temperatureMore Reddish the white light – the lower its color temperature.
31Light, Color, Lighting Kelvin Degrees Outdoor Light – much more Bluish than indoor light.Standard Outdoor Illumination Measurement 5600 degrees KStandard Indoor Illumination Measurement 3200 degrees K
32Light, Color, Lighting Gels Color Filter used in Studio and Field lightingAffects light sourceBlue Gel – raises temperature of studio lightRed Gel – lowers temperature of studio light.
33Light, Color, Lighting White Balancing Adjusting the camera so it reproduces a white object as white on the screen Regardless of whether it is illuminated by a high color temperature source or a low color temperature source.Required for color continuity.
34Light, Color, Lighting Lighting Instruments Two types: Spotlights Floodlights
35Light, Color, Lighting Spotlights Throw Directional Light Floodlights Lights specific areasSharp beam of lightFloodlightsLights general areaDiffused lightNon-directional
36Light, Color, Lighting Fresnel Spotlight Workhorse of studio spotlightsAllows light beam to be adjustedBarn Doors
59Light, Color, Lighting Field Lighting Scout Ahead Be prepared Do not overload circuitsDo not waste bulb lifeSecure light standsMove equipment carefully
60Light, Color, Lighting Outdoor Lighting The best light Overcast Day (Natural Lighting)
61Light, Color, Lighting Measuring Light Incident Light Baselight level Stand next to talent. Aim a light meter to cameraAim meter at lightsCheck light meter needle readingMaintain same needle reading
62Light, Color, Lighting Reflected Light Stand next to talent and point light meter towards the light and the shadows from the direction of the camera.Difference in readings provides lighting contrast.Use video monitor as best guide
