Two parts of the human eye
that regulate the ability to detect color and brightness include the rods and
the cones. The rods allow the eye to discern the difference between dark and
light images. The cones allow the eye to discern all colors in the color
spectrum while the rods operate on the grey scale. There are red cones, blue
clones, and green clones which mix different levels of light to generate all
the colors in the color spectrum.

1080i and 1080p are two
different ways of displaying pixels on a television or monitor. The “i” in 1080
stands for interlaced scan while the “p” stands for progressive scan. A 1080i
resolution operates at a wide-screen viewing ration of 16:9. Although 1080p
operates at the same ration, its frames are not interlaced, but are instead progressively
drawn line after line to produce a more vibrant picture.

Megabits and Megabytes are
two different measurements used in the world of video for describing amounts of
memory/ file storage space, or operating speed. One megabyte is equal to eight
megabits.

Three different type of
lights that can be used in three point lighting include existing light,
modified light, and created light. Existing light is simply light that already
exists and requires no adjustments. Modified light is light that has been
altered to create a specific look. Created light is extra artificial lighting
that has been added to a scene. With that understanding in place, there are
also different lighting methods that produce either incandescent light,
florescent light, or L.E.D. light. Incandescent lights use filament, that when
heated by electricity glows like a traditional lamp light bulb. Florescent
lights use mercury vapor and electricity usually used for overhead lighting.
5. When lighting a subject, the concept of falloff has to do with
the difference and contrast of shadows that the lights cast. Fast falloff
creates much harsher shadows that are high in contrast and go from light to
dark very quickly. Slow falloff is simply the opposite effect in which there
are more visable areas of grey that can be noticed between the different
contrasts of light and shadow.

Trucking is a movement that involves sliding the camera from left to
right. Dollying has a double definition that refers to a rolling stand
the camera is mounted on as well as the motion of moving in and out on a
subject. Panning a movement that involves aiming the camera from left to
right while set on a stable tripod.
