Instructions:

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. What is the inverse square law?
1 1/3 stops
Curves adjustment; Levels adjustment; Brighteness/Contrast adjustment
(X times Y = exposure) Intensity (aperture) x Time (shutter)
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.

2. What is the name of the technique used to make a monitor look like what you will see on your print?

Similar to a normal lens at about 30 degrees

46. The smallest unit of digital information is called a what?
lens-to-subject distance
Bit
Hyperfocal distance. A lens focused at the hyperfocal distance has depth of field extending from approximately half the hyperfocal distance to infinity - whereas a lens focused at infinity has a depth of field only at infinity.
It should match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely to occur with wide angle of 28mm and below.

47. When doing close-up work - what happens to the depth of field when the subject is closer to the lens?
International Organization for Standardization
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.
In the middle
It should match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely to occur with wide angle of 28mm and below.

48. This technique allows you to keep a subject that is moving toward you well focused.
Butterfly lighting
Through the Lens. A camera that can automatically control flash exposure using sensors inside the camera.
Follow focus
No change. The EXPOSURE doesn't change or it would also change the background as well. Move the lights to adjust.

49. What is an element and where is it found?
The brightness of all the pixels in an image
The entire range of colors that can be seen - reproduced - or captured. Our eyes have a greater gamut than a print or monitor.
A simple lens with two curved sides or one curved and one flat side; found in a compound lens.
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to make the scene 18% gray - employ overexposure to adjust.

50. A tonal correction cannot be accomplished by using a...
A high contrast image
hue/saturation adjustment layer
