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.

With the Main at 45 degrees to one side and 45 degrees above subject - it is a classic angle for portraits. It seems natural and flattering and models the face into 3D form.
1 or 2
5000K

2. What does side lighting emphasize?
International Organization for Standardization

emphasizes textures
1 or 2

3. A 1:1 lighting ratio produces what lighting result?

Along the lines of an imaginary grid at intersecting points that divide the image into thirds horizontally and vertically

6. What would you use an ICC profile for?
With the Main at 45 degrees to one side and 45 degrees above subject - it is a classic angle for portraits. It seems natural and flattering and models the face into 3D form.
