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 a BYTE?
An 8-BIT sequence that represents 256 possibilities - black & white & 254 shades of grey. The size of a file is the number of bytes it contains.
Click with the neutral-point dropper on the selected color
stopped down
Use negative exposure compensation (underexpose). The meter will attempt to make the dark scene 18% grey - underexpose to bring it back to dark.

2. Why is depth of field greater on a short lens versus a long lens?
High Dynamic Range
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.

The brightness of all the pixels in an image

3. All objects beyond the closest distance in focus will be sharp when this appears within the DOF scale.

A new layer
ISO

8. What Photoshop tool allows you to select an area of any size or shape by drawing freehand?
