无论是在编辑电视气象新闻和气象科普专题节目时,我们常常会面对一大堆的拍摄素材,尤其是有一部分初学摄像朋友提供的原始素材而发愁,搜寻很多录象带从中很难找到符合节目制作标准的素材。这些素材带中普遍存在画面上下左右摇晃、抖动,颜色和构图缺乏美感,盲目的推、拉、摇、移而且没有节奏感。想要拍摄出高质量的影像素材,提高后期编辑制作的效率,那就要求我们无论是摄像发烧友还是准备从事专业摄像工作的朋友,从拿起摄像机的那一刻开始就要注意培养练就摄像的基本功。 相似文献

有摄影人说,摄影就像农民种田要靠天吃饭一样,在进行摄影特别是风光摄影时,天气是主要因素。如果空气清新、天空通透、蓝天白云,美丽风光就会尽收眼底。什么天气条件下才能空气通透、风轻云淡、万里风光一览无余呢?我们说的天气通透,是指大气能见度好。 相似文献

A comparison is made of the high-speed (2000 fps) lightning between two techniques. The analysis shows (UPL) in altitude-triggered negative lightning (ATNL) photographic records in rocket-triggered negative that: the initial speed of upward positive leader is about one order of magnitude less than that in classically triggered negative lightning (CTNL), while the triggering height of ATNL is higher than that of CTNL; the afterglow time of metal-vaporized part of the lightning channel can endure for about 160-170 ms, thus the luminosity of the air-ionized part can reflect the characteristics of the current in the lightning channel better than that of the metal-vaporized part. According to the different characteristics of the luminosity change of the lightning channel, together with the observation of the electric field changes, three kinds of processes after return-stroke (RS) can be distinguished: the continuous decaying type without M component, the isolated type and the continuing type with M component, corresponding to different wave shapes of the continuous current. The geometric mean of the interval of RS with M component is 77 ms, longer than that (37 ms) of RS without M component. And the initial continuous current (ICC) with M component also has a longer duration compared to the ICC without M component. The distinction in the relative luminosity between the lightning channel before RS and that before M component is obvious: the former is very weak or even cannot be observed, while the latter is still considerably luminous. 相似文献
