[6-05] "glossary"

50mm—most common focal length; perspective that falls between wide and long lenses; considered the native perspective of our eyes (though I don't know why; this has always been strange because our eyes are so wide in vision, though our attention is more focused in the center of our sight)

battery grip—an accessory to a camera that provide more battery life, and provides a second trigger position (right hand)

aperture-priority—a common way to set exposure calculation; photographer chooses an aperture, so the camera determines ISO and shutter speed based on the available light and the metering pattern

metering pattern—what areas of an image the camera calculates to estimate the right exposure

exposure compensation—deviations from 0.0, instructing the computer to bias calculations to be brighter or darker

auto-iso—in manual mode; when aperture and shutter speed are declared, camera will determine the ideal ISO for proper exposure

full-manual—how I photograph in the studio; the camera adjust nothing; the shutter speed, aperture, and ISO are pre-determined, not influenced by the camera's computer; maximum control for controlled lighting situations

shutter-priority—shutter speed chosen, camera determines aperture and ISO

lens—real simply, what allows an object in the distance to become an object on a surface, because rays of light that exit each point on an object converge to a single point on the sensor, create a sharp image
