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. Why is depth of field greater on a short lens versus a long lens?
The entire range of colors that can be seen - reproduced - or captured. Our eyes have a greater gamut than a print or monitor.
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.
Add cyan
Black. Subtractive primaries are Magenta - Yellow - Cyan

2. What does "photomacrograph" or "macrophotograph" mean?
Selectively increasing print exposure - which will make select parts of the image darker
