This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. Generally - traditional portraits use what lighting ratio?
Reflected light meter
3:1 or 4:1

The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject - the light illuminates only 1/4 of the original.
Use negative exposure compensation (underexpose). The meter will attempt to make the dark scene 18% grey - underexpose to bring it back to dark.
Also called a gobo; it is a small panel usually mounted on a stand that shades some part of the subject or shields the lens from light that could cause flare
lengthen (or slow) the shutter speed
