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 does the term "stop" mean?

2. Convex lenses cause light rays to do what?
Yellow
bend toward each other and converge at the focal point.

3. Panning does what?
Fair Use
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.
Keeps a moving subject sharp while blurring the background

4. An in-camera reflected meter reading a very light toned scene indicates an exposure of 1/250th at f/8. For a correct exposure - what should you do?
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to make the scene 18% gray - employ overexposure to adjust.
