Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

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. Instead of permanently altering your image when adjusting for color and value - what should you do?

Blue

2. What color is between Magenta and Cyan on the color wheel?
Blue
The brightness of the light that reaches the sensor
Reflected light meter
It should match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely to occur with wide angle of 28mm and below.

3. 8 bits per pixel gives you how many colors?
Reciprocal relationship
factor of 2 = 1 stop compensation. (Each time a factor doubles - it's one additional stop)
Small light source at an angle to the subject
256

Add blue
Red - Yellow - Green - Cyan - Blue - Magenta
Because you can move in close to the subject
