Shutter release button 45 RECORDING IMAGES · When performing this step, take care so your fingers do not block the lens or any of the sensors. About the REC Mode Monitor Screen · The image shown on the monitor screen in the REC mode is a simplified image for composing purposes. The actual image is recorded in accordance with the image quality setting currently selected on your camera. The image saved on the memory card has much better resolution and detail than the REC mode monitor screen image. · Certain levels of subject brightness can cause the response of the REC mode monitor screen to slow down, which causes some static noise in the monitor screen image. 5. Press the shutter release button the rest of the way to record the image. · Recorded images are temporarily stored in a buffer, from which they are saved on the memory card installed in the camera. You can continue to store images as long as there is space available in the buffer. · The number of images you can store in the camera depends on the storage medium and the image quality setting (page 56) you are using. · To avoid hand movement, press the shutter release button gently. · When available lighting is dim, use of a tripod is recommended to protect against hand movement. Recording Precautions · Never open the battery cover, disconnect the AC adaptor from the camera, or unplug the adaptor from the wall socket while the operation lamp is flashing green. Doing so will not only make storage of the current image impossible, it can also corrupt other image data already saved on the camera's memory card. · Never remove batteries, unplug the AC adapter, or remove the memory card while the camera is saving images. · Fluorescent lighting actually flickers at a frequency that cannot be detected by the human eye. When using the camera indoors under such lighting, you may experience some brightness or color problems with recorded images. 46 RECORDING IMAGES Image Recording when Batteries are Low Normally, the camera temporarily stores images you record into buffer memory, and then transfers them to the memory card. This is done in order to shorten the wait time between on the shots. When the battery level is indicated by monitor screen, however, the camera bypasses buffer memory and saves images directly to the memory card. This causes the wait interval between shots to become longer than it usually is. Using Zoom You can use the digital zoom feature of your camera to zoom in on the center of an image. Performing a zoom operation toggles the zoom factor between 2X and 1X. 1. In a recording mode, to press change the zoom factor.
