  • SPECULAR HIGHLIGHT: a bright spot of light that reflects on shiny objects when illuminated by a hard light, a strong 3d visual cue.

  • HARD LIGHT: a light source that is relatively small and far away (such as the sun) and creates harsh, sharp-edged shadows and reveals textures.

  • SOFT LIGHT: a light source that is relatively large and close to the subject that creates soft edged shadow transitions and conceals textures.

  • DIFFUSER: a translucent device such as a softbox or umbrella that spreads the light from a hard light to soften the light and reduce harsh shadows

  • REFLECTOR: a device that is used to redirect light towards a given subject to fill in and lessen shadows

  • MODIFIER: any kind of device used with light sources to alter the direction, quality, or color of photographic light

  • LIGHT: the portion of the electromagnetic spectrum that is visible to the human eye.

  • COLOR TEMPERATURE: a measurement scale in degrees Kelvin that indicates the hue (color cast) of a particular light source

  • KELVIN: a unit of measure for color temperature

  • TUNGSTEN: also known as an incandescent light bulb, a globe shaped bulb that produces light with a heated wire filament that gives off a yellowish cast.

  • FLUORESCENT: a light bulb which uses a tube filled with mercury vapor gas which is charged to produce light that gives off a greenish cast

  • WHITE BALANCE: a camera color temperature adjustment to remove unrealistic color casts making white objects appear white in the image.  (The "L" in LISA)

  • DAYLIGHT WB: a camera white balance preset that assumes the light source is the sun on a clear day (about 5200k)

  • SHADE WB: a camera white balance preset that assumes the subject is in the shade (about 7000k)

  • CLOUDY WB: a camera white balance preset that assumes the subject is in an overcast sky (about 6000k)

  • TUNGSTEN WB: a camera white balance preset that assumes the subject in light from a TUNGSTEN light bulb (about 3200k)

  • FLUORESCENT WB: a camera white balance preset that assumes the subject is in light form a FLUORESCENT light bulb (about 4000k)
