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. To produce optimal sharpness - detail - and resolution - is a higher or lower ISO setting better?
Lower
Bit
Metamerism
The distance between the lens rear nodal point and the focal plane when the lens is focused at infinity.

No
Curves adjustment; Levels adjustment; Brighteness/Contrast adjustment
