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. Most inkjet printers intended for photographic printing include light and dark inks of all of the colors except for one. Which color ink is usually available only in one density?

It increases
Close-ups that are life-size or larger. Images through microscopes are "photomicrographs."

3. What is the usable exposure range - or range of subject brightness called?
Curves adjustment; Levels adjustment; Brighteness/Contrast adjustment
