Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
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. What angle of view does an incident meter read?
No change. The EXPOSURE doesn't change or it would also change the background as well. Move the lights to adjust.
Blown highlights
Very wide at about 180 degrees
A mathematical translator assigned to each piece of equipment you use (they map one gamut to another; and the ICC (or International Color Consortium) profile is usually shipped by the equipment manufacturer).

2. 8 bits per pixel gives you how many colors?

3. What is the name of the issue that prevents you from seeing exactly what the lens sees when using a rangefinder camera?
Parallax
Aperture - focal length - and distance to the subject
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.
lengthen (or slow) the shutter speed

4. What do the bars on the left of a histogram represent?
