		<description><![CDATA[第一次拍攝閃電。
那一晚大約凌晨兩時多，見閃光不斷，即到書房架起相機。但見窗外陰雲密佈，風勢頗大；未幾，即雷雨大作。試拍多幅，但只見相片濛濛，經過一個多小時，仍未能成功，其時睡意侵襲，決定了放棄而收拾相機，回到廳房上天文台網頁查看當時雷電分佈圖及雨量分佈，見雨雲正離開荃灣一帶，心想或許再過一會會有轉機。果然凌晨四時多，雨等了，風亦靜下來，終見到閃電在遠處由天空打落地面，清晰可見，連忙再架起相機。用 F8~F11光圈，ISO400 及30秒曝光時間，用RAW format 連續拍攝，終於捕捉到以下兩張相片！ 可惜的是，我的相機竟然在這最佳的拍攝時機用光了電。






P.S. 當我將相片上傳到電腦一看，發覺用F14以上光圈, ISO200 效果應該會更好。期待下次的機會！
