拍摄雨景有哪些方法与技巧</SPAN></SPAN>
现在娱乐休闲成了人们工作之余的乐趣，特别是雨天，空气清新，花草树木都非常的洁净，一尘不染，很多摄影爱好者都想借此留下纯净的一幕。</SPAN>北京摄影学校</SPAN></SPAN></SPAN>的专家为您提供了如下雨天摄影的技巧：</SPAN>
</SPAN>　　</SPAN>1. </SPAN>雨天拍摄</SPAN>,</SPAN>常常会出现曝光偏多的现象</SPAN>,</SPAN>而曝光过度对表现雨景是极为不利的</SPAN>.</SPAN>因为雨天景物反差小</SPAN>,</SPAN>曝光过度会使反差更小</SPAN>,</SPAN>照片看起来是灰蒙蒙一片</SPAN>.</SPAN>所以</SPAN>,</SPAN>一般多采用减少曝光</SPAN>,</SPAN>延长显影的办法</SPAN>,</SPAN>来改善反差的情况</SPAN>.</SPAN>可按正常曝光量减少一挡到一挡半</SPAN>,</SPAN>每减少一挡时</SPAN>,</SPAN>可增加</SPAN>20%-30%</SPAN>的显影时间</SPAN>,</SPAN>这样有助于提高画面反差。</SPAN>
2. </SPAN>雨天光线变化很大</SPAN>,</SPAN>有时雨景亮度很高</SPAN>,</SPAN>而乌云密布的倾盆大雨亮度又很低</SPAN>,</SPAN>两者之间的曝光量可以相差很多倍</SPAN>.</SPAN>因此拍摄时</SPAN>,</SPAN>最好使用测光表测光。</SPAN>
 </SPAN>
   </SPAN> </SPAN>3. </SPAN>拍雨景时</SPAN>,</SPAN>不要以天空为背景</SPAN>,</SPAN>而应选择深色背景</SPAN>,</SPAN>这样才能把明亮的雨丝衬托出来</SPAN>.</SPAN>如果画面中有水</SPAN>,</SPAN>不论是河湖水面</SPAN>,</SPAN>或是街道上的积水</SPAN>,</SPAN>雨点落在水面上溅起的一层层涟漪</SPAN>,</SPAN>也有助于雨景的表现。</SPAN>
</SPAN>　</SPAN>4. </SPAN>拍摄雨景时</SPAN>,</SPAN>要注意在镜头和雨点之间要拉开距离</SPAN>.</SPAN>雨滴离镜头过近时</SPAN>,</SPAN>一滴很小的雨点也会遮住远处的景物</SPAN>.</SPAN>当然</SPAN>,</SPAN>有时也会有意需要这种特殊效果</SPAN>.</SPAN>要注意相机不能淋雨</SPAN>,</SPAN>也不要使镜头溅上雨点</SPAN>.</SPAN>一般可用雨伞遮住或把相机装在塑料袋里</SPAN>,</SPAN>把镜头和取景部位露出。</SPAN>
5. </SPAN>雨水不会是垂直落到地面</SPAN>,</SPAN>一般以选择雨丝成</SPAN>45?</SPAN>方向时为合宜</SPAN>.</SPAN>使用的快门速度不可太高</SPAN>,</SPAN>因为高速度会把雨水凝住</SPAN>,</SPAN>形成一个个小点</SPAN>,</SPAN>而没有雨水的感觉</SPAN>.</SPAN>如果使用的快门速度太慢时</SPAN>,</SPAN>雨水会拉成长条</SPAN>,</SPAN>效果也不好</SPAN>.</SPAN>一般以使用</SPAN>1/30</SPAN>秒到</SPAN>1/60</SPAN>秒速度为好</SPAN>,</SPAN>这时快门速度不高</SPAN>,</SPAN>可以强调雨水降落时的动感。</SPAN>
  </SPAN>6. </SPAN>在室内</SPAN>,</SPAN>如想透过窗子表现室外雨景时</SPAN>,</SPAN>可在室外玻璃窗上涂上薄薄的一层油</SPAN>.</SPAN>这样</SPAN>,</SPAN>水珠容易挂在玻璃上</SPAN>,</SPAN>渲染雨天的气氛。</SPAN>
 </SPAN>7. </SPAN>拍雨天的夜景时</SPAN>,</SPAN>因为灯光的反射以及地上水面的倒影</SPAN>,</SPAN>都会使画面显得很生动</SPAN>.</SPAN>尤其是</SPAN>,</SPAN>使用彩色片拍摄时</SPAN>,</SPAN>雨天夜景的色彩效果要比一般夜景更为丰富。</SPAN>
8. </SPAN>用彩色片拍雨景时</SPAN>,</SPAN>由于阴雨天的光线色温高</SPAN>,</SPAN>使用日光片时</SPAN>,</SPAN>照片会出现明显的偏兰色调</SPAN>.</SPAN>这种偏色可不用校正</SPAN>,</SPAN>因为兰调可渲染雨天寒冷的感觉。</SPAN>
