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. If an image is too yellow - what color adjustment should be made in Photoshop to correct it?
Add blue
Variations command

4. Using this kind of automatic exposure setting on the camera - you set the shutter speed and the camera sets the aperture.
Add yellow
Shutter-Priority
Aperture-Priority
Front lighting


5. What image adjustment tool uses a histogram display to alter an image?
Half as much light
High Dynamic Range
Infrared
Levels adjustment


6. What kind of lighting pattern is useful to widen a subject?

Add red
Broad lighting
flat - low contrast light


7. What is interpolated resolution?
1 or 2
Soft proofing
A RAW file that has been altered
On a scanner; it guesses what the pixels look like in between the ones the scanner can actually measure.


8. What is the inverse square law?

Soft proofing
Levels adjustment
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.

Change the shutter speed. The longer the shutter speed - the lighter the background will be. The faster the shutter speed - the darker the background will be because less existing light is captured.
The diagonal measurement of the sensor.
