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. When buying a lens hood - you should get it in what size relative to the lens?

2. Using this kind of automatic exposure setting on the camera - you set the shutter speed and the camera sets the aperture.
A new layer
Hue - Luminance - Saturation
emphasizes textures
Shutter-Priority

3. If an image is too green - what color adjustment should be made in Photoshop to correct it?

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
The number of pixels per unit of length in a image
Add magenta

4. Can you save layers in a JPEG file format?
Add blue
dynamic range (not to be confused with gamut)
Aperture-priority
No

5. What angle of view does a reflected light meter read?
dynamic range (not to be confused with gamut)
Follow focus
Metadata fields that hold info on photographer - subject - and use.
Similar to a normal lens at about 30 degrees

6. Resolution refers to what?
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to make the scene 18% gray - employ overexposure to adjust.
The number of pixels per unit of length in a image
factor of 2 = 1 stop compensation. (Each time a factor doubles - it's one additional stop)
RAID system

7. What is the general rule of thumb for the measurement of a 'normal' lens?
The number of pixels per unit of length in a image
Bit
The diagonal measurement of the sensor.
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.

8. As the aperture is stopped down - what happens to sharpness?
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.
Selectively increasing print exposure - which will make select parts of the image darker
More of the background and foreground are sharp.
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.
