Shutter SpeedIntroductionShutter speed and aperture settings control the quality of exposure inphotography. Understand the effect one has on the other.Shutter speedShutter speed is the amount of time, in fractions of a second, that it takes theopening in the shutter curtain to pass across the film surface.Shutter speedsettingsA dial on the camera body is marked with industry standard shutter-speedsettings of T or , B, 1, ½, l/4 l/8 l/15, l/30, l/60, l/125, l/250, l/500,l/1000, and l/2000. Select’the interval you want the shutter to remain openby moving a lever or dial to that particular setting. It should easily click intoplace. You cannot select a shutter speed in between two indicated speeds.T or : At the setting marked “T or , ” the shutter opens the first time theshutter-release button is pressed and remains open until the shutter-releasebutton is pressed again.B: At the setting marked “B,” the shutter remains open as long as theshutter-release button is held down and closes when released.l/30: This setting is the longest recommended shutter speed for hand-heldexposures. For any setting longer than l/30 second, set the camera on atripod or sturdy support.l/60: This is generally the recommended shutter speed for flash photographs.At this speed, the shutter speed, aperture, and flash are synchronized foroptimum exposure. Flash synchronization may also be indicated by numbersin red or another color or by a lightning bolt on the shutter speed dial.Long (slow) shutter speeds: Slower shutter speeds (T or , B, 1, l/2, l/4,l/8,, l/15, and l/30) require more stable platforms or tripods to minimizeblur. Not intended to stop action, slow shutter speeds work best in low lightsituations with little movement. The results can be very fine grain, overallimage sharpness, and subtle gradations of tone.Short (fast) shutter speeds: With faster shutter speeds (l/60, l/125, l/250,l/1000, and l/2000), the faster the shutter speed, the more likely you are tostop action. One drawback to faster shutter speeds is that less of the overallimage will be focused.Continued on next page7-22
