References Useful Information Hints for Better Shooting • Position the subject in the center of the screen. When you are using auto focus, whatever is in the center of the screen is kept in focus. Lighting For clear, good-quality recording, 500 to 100,000 lux is needed. Recording is possible with less light, but the picture quality may suffer. Adequate lighting is also essential for correct white balance. Brightness (Lux) Situation (Lux) Blue sky Position the subject in the center. Focus manually when you need to position the subject off center (see page 48). • Avoid backlit subjects. For the best picture, shoot with the light source behind you. When the background is brighter than the subject, the subject often becomes too dark. If you have to record with this lighting, use the Gamma Brightness Compensation or correct the exposure level to improve the picture (see pages 34 and 50). Light from behind Backlighting • Before zooming, think about how to best frame the shot. Frequent zooming produces unattractive pictures. It also increases the battery power consumption. • When image shakes are noticeable during zoomed-in telephoto shooting, use a tripod, use the DIS function (see page 30), or push the Power Zoom control to the W side to zoom out. • Horizontal panning (lateral movement) and tilting (vertical movement) should be done slowly to emphasize the wide expanse of a scene or the height of a building, and to make scenes easy to watch during playback. • Use a wide-angle setting for fast-moving subjects. 100,000 Clear day at noon (100,000) ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ Clear day at 10 am (65,000) Optimal lighting range 10,000 Clear day at 3 pm (35,000) Cloudy day at noon (32,000) Cloudy day at 10 am (25,000) ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ Cloudy day, one hour after sunrise (2,000) Clear day, one hour before sunset (1,000) 1,000 Fluorescent light near window (1,000) ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ Factory floor (700-800) Sales counter in department store (500-700) Bowling alley (500) Library (400-500) Office with fluorescent lighting (400-500) ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ Fluorescent desk lamp (400) Flashlight at 3 ft (1 m) (250) 100 Shop stairway (100) ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ During intermission at movie theater (15-35) Cigarette lighter at 1 ft (30 cm) (15-20) Candles on birthday cake at 8 inches (20 cm) (10-15) 10 Candlelight Note: The figures in the chart are approximations. Tips on Good Lighting In most outdoor, daytime scenes, natural lighting is adequate for home videos. Indoors, however, artificial lighting is usually required. Video lights with halogen lamps provide the most natural artificial light over a long operating life. Note: • It may take longer to focus when zooming and panning are used frequently. 56 References
