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.

On a scanner; it guesses what the pixels look like in between the ones the scanner can actually measure.

28. An in-camera reflected meter reading a very dark scene indicates an exposure of 1/250th at f/8. For a correct exposure - what should you do?
aperture diameter
Aperture-priority
Use negative exposure compensation (underexpose). The meter will attempt to make the dark scene 18% grey - underexpose to bring it back to dark.
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.
