14. Side lighting shows more dimension than front lighting. True / False
15. A longer lens is good to use for portrait photography because it will not distort a person’s face.

_____1/250____________________
18. If your camera is set at f4@1/250 for a proper exposure according to your in-camera light meter and you want to shoot two stops more open at 1/60, what would be the proper aperture to produce an equivalent exposure according to the law of reciprocity?
1/250 @ f4 = 1/60 @ ___f8_______________
