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?
factor of 2 = 1 stop compensation. (Each time a factor doubles - it's one additional stop)
Flat lighting
lengthen (or slow) the shutter speed
It emphasizes the edges between tones. A threshold of zero affects all pixels - a higher threshold affects just the edges with high tonal difference and minimizes noise.

2. What is the effect of front lighting?
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.
Flattens out the volume of the subject and minimizes textures
sRGB
Shutter-priority

3. What does a neutral density filter do?
Sensor size - the larger the sensor size - the longer the focal length of a normal lens. (Corresponds to a diagonal line across the frame)
The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject - the light illuminates only 1/4 of the original.
Absorbs equal quantities of all wavelengths of light. It allows you to use wider apertures or slower shutter speeds without changing color balance.
