HDR turns off automatically after the photograph is taken ; to turn off HDR before shooting, rotate the mode dial to a setting other than P, S, A, or M. D Framing HDR Photographs The edges of the image may be cropped out. The desired results may not be achieved if the camera or subject move during shooting. Use of a tripod is recommended. Depending on the scene, shadows may appear around bright objects or halos may appear around dark objects; this effect can be reduced by adjusting the amount of smoothing.
