Chapter A. Appendix

 < Day Day Up > 

Use the following tables as a quick-reference guide for a variety of camera settings. For more detailed explanations of the data listed here, see Chapters 2 and 3.

Table A-1. Exposure compensation reference guide

Lighting situation

Recommended exposure compensation (via the scale setting)

Subject against a bright sky background (high clouds on sunny day)

Overexpose by 2 (+2.0); use fill flash if within 10 feet

Light object (white color), front lit

Overexpose by 1.5 (+1.5)

Subject against white sand or snow (e.g., person skiing)

Overexpose by 1.5 (+1.5)

Landscape scene dominated by bright, hazy sky

Overexpose by 1 (+1.0)

Fair-skinned subjects with bright front lighting

Overexpose by .5 (+.5)

Subject against green foliage in open sun (e.g., outdoor portrait with background trees and shrubs)

No compensation

Dark-skinned subjects with bright front lighting

Underexpose by .5 ( .5)

Brightly lit subject against dark background (e.g., theater lighting)

Underexpose by 1 ( 1.0)

Dark object (black color), front lit

Underexpose by 1.5 ( 1.5)


Table A-2. Flash mode settings

situation

Recommended flash mode [1]

Outdoor portrait in open shade or sun

Fill flash (flash forced on)

Subject against bright background, such as hazy sky

Fill flash (flash forced on)

Weddings and other special events (both indoor and outdoor shooting)

Fill flash (flash forced on)

Subject in brightly lit evening scene, such as Times Square, New York, or Sunset Strip, Las Vegas

Slow-synchro flash (hold camera steady or use tripod)

Portrait against twilight sky, brightly lit monument, or building

Slow-synchro flash (hold camera steady or use tripod)

Portrait in brightly lit room where ambient lighting needs to be preserved

Slow-synchro flash (hold camera steady or use tripod)

Subject who typically blinks as flash fires

Red eye reduction flash (to eliminate recorded blinking)

Mood portrait by window, bright lamp, or other light source

Flash off (steady camera with tripod or other support)

Sporting event or outdoor concert when shooting from the stands

Flash off (steady camera with tripod or other support)


[1] On some point-and-shoot cameras, these flash settings are accessible only when you enable manual mode. Cameras typically ship in automatic mode, which limits the number of adjustments that the photographer can change. Refer to your owner's manual for more information.

Table A-3. White balance settings

Lighting condition

Recommended white balance setting

Sunny, outdoor conditions

Auto or Daylight

Open shade (e.g., under a tree), indoor portraits by window light, or when flash is on indoors

Cloudy (add fill flash when possible)

Snow setting, bluish winter light, or when overall light balance is too "cool"

Cloudy

Indoors with flash off, when dominant light source is tungsten light

Tungsten

Outdoors at sunset or sunrise, when light is too "warm"

Tungsten

Indoors, when dominant light source is fluorescent tubes

Fluorescent


Table A-4. Camera modes with explanations

Camera mode [2]

Explanation

Programmed autoexposure (P)

Camera sets both aperture and shutter speed. Good for general photography.

Shutter priority/timed value (S or Tv)

Photographer sets shutter speed and camera sets corresponding aperture. Best for action, sports, or running water photography.

Aperture priority/aperture value (Av)

Photographer sets aperture and camera sets corresponding shutter speed. Best for landscape photography or any situation that requires depth of field control.

Manual (M)

Photographer sets both aperture and shutter speed. Advanced mode for those with an understanding of photography.

Movie

Camera records video segments and saves them as QuickTime, AVI, or MPEG files. Some models also record sound to accompany the video.

Panorama

Camera designates a sequence of shots to be later "stitched together" to create one image with a wide perspective. Some cameras give you onscreen assistance to line up the sequence.

Nighttime

Allows for longer shutter speeds (even when the flash is enabled) to enable photography in low ambient light, such as at sunset or for brightly lit interiors. A tripod should be used to help steady the camera when using this mode.


[2] Your camera may have all, some, or only a couple of these modes available. Typically, aperture priority, shutter priority, and manual modes are available only on advanced models.

Table A-5. Metering modes with explanations

Metering mode [3]

Explanation

Evaluative metering

Camera divides viewing area into "segments" and evaluates each area alone and in combination with others. End result is very accurate overall exposure for most scenes. Good choice for general photography.

Spot metering

Camera reads only center portion of viewing area, usually within the center brackets or crosshairs. Good choice for situations that require precise exposure control on a particular element in the scene. Most popular use is to correctly meter a person's face in difficult lighting situations.

Center-weighted metering

Camera reads entire viewfinder area, but with more emphasis placed on central portion of scene. Typically used for landscape and general photography. Evaluative metering is usually preferred over center weighted metering.


[3] Many point-and-shoot cameras offer only one metering mode usually center-weighted or evaluative. Intermediate and advanced models usually include spot metering, too.

[5] The number of pictures listed for each memory card size in this table is for images saved at the highest quality setting in the JPEG format. You can "squeeze" more pictures onto a card by lowering the quality setting, but this is not recommended. Different camera brands may produce results slightly different from those shown here.
