C. c++中的long代表什么意思,怎么个用法

1. long是长整形，使用方法和int相同，表达的数据范围跟平台有关。
   16位编译器运闭下，一般的int型是2字节，long型是4字节的，就是说long型的数据能表示的数值更大一些。16位旁首裂编译器下芹歼 long == int，同为4字节。
   

2. 输入输出该类型时，应该使用%ld参数，例如scanf("%ld",&a);。
   
   

D. 相机长时间曝光是什么意思

长曝光摄影即长时间曝光摄影（Long exposure photography），是一种长时间开启快门的摄影技巧。常用于夜间摄影、光迹摄影、水景摄影。

相机的“B门”和“T门”是一种能够进行长时间曝光的功能，利用该功能够获得长达几秒、几分钟甚至几小时的曝光，是天体摄影、烟花夜景拍摄必备的一种快门功能。市场上销售的数码相机只有B门，没有T门，而有些小型轻便数码相机则B门和T门功能都不具备。

长曝光是选慢快门（曝光时间长）的一种曝光方式。好处就是可以把光线暗的景色拍的更清晰，也可以拍出如梦幻般的画面，比如瀑布和城市公路夜景。长曝光摄影需要使用一个长时间的快门速度大幅捕捉固定元素的图像模糊,而它的移动,或遮蔽丑化元素。

1、夜间摄影

长时间曝光摄影，通常用于夜间摄影，以产生有别于白天时间的画面。借由延长相机的快门开放时间，以吸收更多的光线，创造一个更清晰的照片。通常会以角架固定，避免模糊。并放大光圈，避免曝光不足，导致照片一片漆黑。

2、光迹摄影

用这种技术时，场景将保持相当的暗，而照相者或助手拿一个光源——可以是一只小手电筒——并移动之画出图形。光源可以在不同笔画间关掉。通常在景中不动的物件会被短暂开启的录像室灯光、一个或更多闪光灯、或逐渐放大的光圈描绘。

3、水景摄影

长时间曝光摄影，能够白雾化模糊移动中的水，并保持静止物体的清晰感，借以表现出水流的动感。

F. 照相机的 “长镜头” 英语怎么说

这个局辩卜问题不太好回答。

长镜头——
指的是焦距长的镜头，还是镜头本身的尺寸比较长？

如果是指镜头的焦距比较长，桐穗也就是我们灶拦常说的长焦镜头，那么英文应该是：telephoto lens。

如果是说镜头比较长的话，应该是：long lens。
