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.

1. A 1:1 lighting ratio produces what lighting result?
Shutter speed & aperture
Also called a gobo; it is a small panel usually mounted on a stand that shades some part of the subject or shields the lens from light that could cause flare

2. An SLR camera uses what to allow you to see exactly what you'll photograph?
Red - Yellow - Green - Cyan - Blue - Magenta
A mirror and pentaprism
flat - low contrast light
JPEG

3. When doing close-up work - what happens to the depth of field when the subject is closer to the lens?
Black. Subtractive primaries are Magenta - Yellow - Cyan
It decreases. A 50mm lens at 12 inches and f/4 has a DOF of 1/16th of an inch. At f/11 - it increases to only 1/2 an inch.
The amount of light reflected back from the subject during exposure.
Relative aperture. The opening on a long lens must be larger than a corresponding opening on a short lens to produce the same f-stops.

4. In a curves adjustment layer - what does the shape of the curve indicate?

15. According to the rule of thirds - where should the important parts of an image fall?
Selectively blocking light during print exposure to lighten the area
Fair Use
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.
