Balancing the flash power and ambient lighting or using off-camera flash can help overcome these issues. Using an umbrella or softbox (the flash will have to be off-camera for this) makes softer shadows. A typical problem with cameras using built-in flash units is the low intensity of the flash; the level of light produced will often not ...
Flash modes allow the user to choose between common settings such as: Fill flash, to always use flash; Auto flash, which will use flash in low-lit areas; Red-eye reduction, which may flash once before the actual photo in order to shrink the subject's pupils and reduce red-eye; or, Flash off, which will never use flash.
The effect is produced by adding a small and even level of exposure to the entire image. Since exposure levels increase logarithmically, this tiny level of additional exposure has no practical effect on an image's mid-tones or highlights, while it shifts the darker areas of the image into the practical sensitivity range, thus allowing the darker areas of the image to show visual detail rather ...
Guide number distances are always measured from the flash device to the subject; if the flash device is detached from the camera, the position of the camera is irrelevant. Furthermore, unless a flash device has an automatic zoom feature that follows the setting of a camera's zoom lens, guide numbers do not vary with the focal length of lenses.
Slang for a small or compact camera that is easy to use because the essential functions are automated. Popular, but with limitations compared with more advanced cameras such as DSLR cameras with larger image sensors. PPI: PixelsPerInch. The number of pixels or picture elements contained in one linear inch in a digitally stored image. PS, PSE
Either the flash is firing too late or the shutter speed is too fast (shutter moving vertically). Note the different exposure levels. In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.

To avoid confusion, some authors (Ray 2000, 310) have used camera exposure to refer to combinations of camera settings. The 1964 ASA standard for automatic exposure controls for cameras, ASA PH2.15-1964 , took the same approach, and also used the more descriptive term camera exposure settings .
