Selectively increasing print exposure - which will make select parts of the image darker

25. Using this kind of automatic exposure setting on the camera - you set the aperture and the camera sets the shutter speed.

To strike the side of the face away from the camera.
Internet = 72 dpi; Newspaper = 150 dpi; Photographic print = 240-300 dpi; Gloss magazine = 400 dpi
Aperture-Priority

26. This type of file format compresses images by discarding pixels; therefore - each time an images is compressed - it loses pixels.
JPEG
It decreases. A 50mm lens at 12 inches and f/4 has a DOF of 1/16th of an inch. At f/11 - it increases to only 1/2 an inch.
1) Use a longer lens; 2) Move closer to the subject

Flattens out the volume of the subject and minimizes textures
Selecting portions of the image based on color
Incident light meter

28. An incident-exposure reading for a fair-skinned subject reads f/8 - 1/125th at 100 ISO. The next subject is very dark skinned. What is the proper exposure for the second subject?
