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.

Selectively increasing print exposure - which will make select parts of the image darker
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to make the scene 18% gray - employ overexposure to adjust.
Close-ups that are life-size or larger. Images through microscopes are "photomicrographs."
