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?
A high contrast image
factor of 2 = 1 stop compensation. (Each time a factor doubles - it's one additional stop)
One stop less
Flat lighting
2. What is a thyristor?

To strike the side of the face away from the camera.
A light-sensitive cell or sensor inside a flash unit that measures the amount of light reflecting off a subject when a flash is used.
A mirror and pentaprism
3. Name 2 ways you can decrease depth of field.
Add magenta

The amount of information contained in each pixel
1) Use a longer lens; 2) Move closer to the subject
4. How does 'unsharp mask' work?
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.

lengthen (or slow) the shutter speed
aperture diameter
5. What is the term used to describe data contained in a digital image?
