3 Light, Color, Lighting Key Terms Key Terms Page 116 Page Terms 25 Terms Read, Study Read, Study

4 Light, Color, Lighting Types of Light Types of Light Directional Directional Diffused Diffused

5 Light, Color, Lighting Directional Light Directional Light Direct Direct Precise Precise Hard Shadows Hard Shadows Used to light specific areas Used to light specific areas Examples – Sun, Flashlight, Car Headlights, Studio spotlights Examples – Sun, Flashlight, Car Headlights, Studio spotlights

6 Light, Color, Lighting Diffused Light Diffused Light General General Not Precise Not Precise Spreads Spreads Seems to come from all directions Seems to come from all directions Used to light large areas Used to light large areas Examples – Fluorescent lights, Classroom, Studio Fill lights (large round lights) Examples – Fluorescent lights, Classroom, Studio Fill lights (large round lights)

7 Light, Color, Lighting Light Intensity Light Intensity Amount of light that falls on a given area. Amount of light that falls on a given area. Measurement – Lux (European Term); Footcandles (American Term) Measurement – Lux (European Term); Footcandles (American Term) Baselight – refers to overall light intensity. Baselight – refers to overall light intensity. Low Baselight – open iris to allow more light into camera. Low Baselight – open iris to allow more light into camera. High Baselight – close down iris to allow less light into camera. High Baselight – close down iris to allow less light into camera.

8 Light, Color, Lighting Baselight Example Baselight Example Holiday Choir Concert – iris on Auto and picture washed out. Iris set at 2.8 +/- 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. Holiday Band/Strings Concert – iris on Manual and iris adjusted to 5.8 to 7 for quality picture.

15 Light, Color, Lighting Cast Shadows Cast Shadows Seen Independent of the object. Seen Independent of the object. Hand shadows on wall Hand shadows on wall Hand not seen – shadow seen Hand not seen – shadow seen

16 Light, Color, Lighting Cast Shadows Cast Shadows Help tell us where things are and when events take place. Help tell us where things are and when events take place. Examples – Shadows of utility poles, traffic signs, building walls. Pg. 123 Examples – Shadows of utility poles, traffic signs, building walls. Pg. 123 Note: Even if Cast Shadows touch the base of the object they remain Cast Shadows NOT Attached Shadows Note: Even if Cast Shadows touch the base of the object they remain Cast Shadows NOT Attached Shadows

17 Light, Color, Lighting Falloff Falloff Indicates the degree of change from light to shadow. 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. The speed with which light area turns into shadow area – the brightness contrast between the light and shadow sides of an object.

18 Light, Color, Lighting Fast Falloff Fast Falloff Change from light to dense shadow is extremely abrupt. Change from light to dense shadow is extremely abrupt. High Contrast between areas. High Contrast between areas. Slow Falloff Slow Falloff Gradual change from light to shadow. Gradual change from light to shadow. Subtle Contrast between areas. Subtle Contrast between areas.

19 Light, Color, Lighting Falloff Falloff Defines the contrast between light and dark areas and how quickly light turns into shadow. Defines the contrast between light and dark areas and how quickly light turns into shadow.

26 White Balance White Balance Not all light sources produce light of the same Whiteness. Not all light sources produce light of the same Whiteness. Examples – candle (reddish); fluorescent (bluish); flashlight ( weak batteries bluish, strong batteries whiter) Examples – candle (reddish); fluorescent (bluish); flashlight ( weak batteries bluish, strong batteries whiter)

27 Light, Color, Lighting Color Temperature Color Temperature Standard by which we measure the relative reddishness or bluishness of white light. Standard by which we measure the relative reddishness or bluishness of white light. Kelvin Degrees Kelvin Degrees Measures the color differences of white light. Measures the color differences of white light.

28 Light, Color, Lighting Kelvin Degrees Kelvin Degrees More Bluish the white light – the higher the color temperature More Bluish the white light – the higher the color temperature More Reddish the white light – the lower its color temperature. More Reddish the white light – the lower its color temperature.

32 Light, Color, Lighting Gels Gels Color Filter used in Studio and Field lighting Color Filter used in Studio and Field lighting Affects light source Affects light source Blue Gel – raises temperature of studio light Blue Gel – raises temperature of studio light Red Gel – lowers temperature of studio light. Red Gel – lowers temperature of studio light.
