在上期介绍了外景拍摄中使用测光表测光的方法。但正确地使用测光表并不能保证拍摄到一张曝光合适的照片。首先,外景环境中亮度最高的部分(如天空)与亮度最低的部分(如浓重的阴影)之间的亮度差在11级光圈左右。而相机可记录的亮度范围大概在7至5级光圈左右。也就是说,在通常的环境中拍摄,我们很难把整个环境都准确地记录下来。这是外景拍摄首先要解决的问题。
In the last section introduced the use of photometry in the location shooting method. However, the proper use of the light meter does not guarantee that a properly exposed photograph will be taken. First, the difference in brightness between the highest-brightness part of the landscape (such as the sky) and the lowest-brightness part (such as a strong shadow) is around the 11-stop aperture. The camera can record the brightness range of about 7 to 5 aperture around. In other words, it is difficult to accurately record the entire environment when shooting in the usual environment. This is the location shooting first problem to be solved.
