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.

bend toward each other and converge at the focal point.
Creates deep shadows in eye pockets - under nose - and chin.
Because you can move in close to the subject

9. What would you use an ICC profile for?
To send accurate color requirements to a printer.
Relative aperture. The opening on a long lens must be larger than a corresponding opening on a short lens to produce the same f-stops.
