Final Quiz: Question & Answer

1.   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.

2.   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.

3.   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.

4.   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.
