backlight
This refers to where the subject's main light source is located. If it is behind the subject, it is called backlight.
basic zone
Any of the following preset modes on a camera: Portrait, Landscape, close-up, sports & night scene modes
blur
The condition of being out of focus. When the picture is in focus, dots will look like dots and lines will look sharp. But the more out of focus the picture is, the more blurry the dots and lines will look. With an SLR camera, the background can be made blurry so that the main subject stands out more.
blurred shots
This occurs when the subject moves while the shutter is open, causing the subject to look blurred in the picture. Sometimes the subject is deliberately blurred. If it occurs unintentionally, the image quality may look worse than an out-of-focus shot.
bounce flash
This is a flash technique where the flash is pointed at a white wall or ceiling to bounce the flash before it reaches the subject. This disperses the flash illumination, creating a softer lighting effect and fewer harsh shadows. Note that bouncing the flash will weaken the intensity of the flash by the time it reaches the subject.
bulb
A shutter feature enabling long exposures. The shutter remains open while the shutter button is held down. The shutter closes when you let go of the shutter button.
