  1. Tungsten or Quartz Halogen • Tungsten filament • Halogen glass • Encased in a glass quartz bulb • 3200 k

  2. Information about pertinent light sources from wikipedia: An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a filament wire heated to a high temperature by an electric current passing through it, until it glows Fresnels are typically made in 8, 6 or 3 inch varieties, referring to the diameter of the lens, with lamps ranging in power from 150 W (typically with a 3-inch fresnel) to 2000 W An HMI lamp uses mercury vapor mixed with metal halides in a quartz-glass envelope, with two tungsten electrodes of medium arc separation A halogen lamp, also known as a tungsten halogen lamp or quartz iodine lamp, is an incandescent lamp that has a small amount of a halogen such as iodine or bromine added. The combination of the halogen gas and the tungsten filament produces a halogen cycle chemical reaction which redeposits evaporated tungsten back onto the filament Kino Flo is best known for its fluorescent tube-based systems that are optimized for the color temperature of film and digital video. These lights provide a relatively compact and efficient way of providing soft lighting. Compared to the original workhorse of motion picture lighting, incandescent lights (and, more recently, HMI lights), Kino Flo tubes produce less heat and fit into smaller spaces, two significant advantages that have made them popular with professionals.

  3. HMI • Also called metal halide • Daylight balanced illumination • 5600k or 6000k • Can fill in shadows without the need for filters

  4. Fluorescents • Kino Flo • Tubes do not flicker or create humming noises • 5500 k

  5. LEDs • Light emitting diodes • Heat free • Flickerless • Silent

  6. Diffusion • Umbrellas • Soft box • Silks • Foam core sheets • Flexfill reflectors

  7. Accessories • French flag • Snoot • Full scrim and half scrim • Cookies • C-stand • Flag

  8. Practical • Using lights already found at a location • Photofloods

  9. Colored Filters and Gels • CTO (color temperature orange) • CTB (color temperature blue)

  10. Three Point Lighting • Key • Fill • Back

  12. Lighting Wide Shots • Should be lit to establish mood and cover the actors’ blocking • The eye is naturally drawn to lighter areas of the frame • The areas where the subjects move is going to be lighter than other areas of the frame • Flags or nets can be used to diminish the light falling onto unimportant areas of the frame

  13. The mood of the shot is established by the relation between the brighter action area and the darker background • Pools of light create visual interest and a look of depth • For naturalistic lighting look at motivating sources of light
