Instructions:

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 should a polarizing filter be to the sun for best results?

3:1 or 4:1
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
Two (f/8 > f/11 > f/16)

2. Convex lenses cause light rays to do what?
The difference between light and dark.
bend toward each other and converge at the focal point.
Aperture and shutter
Infrared

3. What angle of view does a spot meter read?
Along the lines of an imaginary grid at intersecting points that divide the image into thirds horizontally and vertically
3200 Kelvin
It emphasizes the edges between tones. A threshold of zero affects all pixels - a higher threshold affects just the edges with high tonal difference and minimizes noise.

The impression human vision gives
