113f: Changing the Depth of FieldWhen using an aperture with a high f/number or shooting in lowlight scenes, note that camera shake can occur.A higher aperture f/number will make the shutter speed slower.Under low light, the shutter speed can be as long as 30 sec. In suchcases, increase the ISO speed and hold the camera steady or use atripod.The depth of field depends not only on the aperture, but also onthe lens and on the subject distance.Since wide-angle lenses have a wide depth of field (range ofacceptable focus in front of and behind the point of focus), you neednot set a high aperture f/number to obtain a sharp picture from theforeground to the background. On the other hand, a telephoto lenshas a narrow depth of field.The closer the subject, the narrower the depth of field. A farthersubject will have a wider depth of field.Set the aperture so that the shutter speed display does notblink.If you press the shutter button halfway and changethe aperture while the shutter speed is displayed,the shutter speed display will also change tomaintain the same exposure (amount of lightreaching the image sensor). If you exceed theadjustable shutter speed range, the shutter speeddisplay will blink to indicate that the standardexposure cannot be obtained.If the picture will be too dark, the “30"” (30 sec.) shutter speeddisplay will blink. If this happens, turn the <6> dial to the left to seta lower aperture f/number or increase the ISO speed.If the picture will be too bright, the “4000” (1/4000 sec.) shutterspeed display will blink. If this happens, turn the <6> dial to theright to set a higher aperture f/number or decrease the ISO speed.Shooting TipsCOPY
