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. Printers use what set of colors?

7. A magic wand tool is used for what?
1 1/3 stops
Through the Lens. A camera that can automatically control flash exposure using sensors inside the camera.
Selecting portions of the image based on color
Absorbs equal quantities of all wavelengths of light. It allows you to use wider apertures or slower shutter speeds without changing color balance.

8. What are luminance and illuminance?
To create a 1-stop difference - multiply the original distance by 1.4. Example - if you were originally 5 feet away - a 1-stop difference would have you step back to 7 feet.
