Tip for Using the Self-timer (p. 59) Normally, the camera shakes a little when you press the shutter button. Setting the self-timer to delays the shutter release for 2 seconds and allows the camera to stop shaking, thus preventing a blurred image. Even better results can be obtained by placing the camera on a stable surface or by using a tripod to shoot. Exposure Compensation (p. 90) This camera automatically adjusts the exposure to shoot images with the optimal brightness. However, recorded images may sometimes be brighter or darker than the actual image depending on the shooting conditions. If this happens, adjust the exposure compensation manually. zUnderexposure The whole recorded image is dark, which makes white elements of the image appear gray. Shooting bright subjects or in backlit conditions may cause the 10 image to be underexposed. Adjust the exposure compensation towards the (+) end. zOptimal Exposure Appendix zOverexposure The whole recorded image is bright, which makes black elements of the image appear gray. Shooting dark subjects or in dark places may cause the image to be overexposed. Adjust the exposure compensation towards the (-) end. 175
