Contrast
Short lighting.
Red - Yellow - Green - Cyan - Blue - Magenta
3:1 or 4:1
25. What is a derivative file?
Because you can move in close to the subject
Use negative exposure compensation (underexpose). The meter will attempt to make the dark scene 18% grey - underexpose to bring it back to dark.

A RAW file that has been altered
26. The greatest tonal range from black to white is achievable on what kind of paper?
Glossy paper
Add yellow
The difference between light and dark.

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.

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
