宽容度这个概念是在胶片摄影时代产生的。一般讲到宽容度,是指胶片能够“承受”的曝光范围,这个范围常用光圈级数的差来表示,假如在某种胶片上可以生成的最大密度和最低密度之间,存在光圈级数为10的差别,那么我们通常就说这种胶片的宽容度为10级。宽容度的概念指出一个事实:假如胶片的宽容度为10级,那么意味着如果你想表现11级或更多级以上的曝光差异,你的努 The concept of tolerance is created in the age of film photography. Generally speaking of tolerance refers to the film can “bear ” exposure range, the range of commonly used aperture series to represent the difference, if the film can be generated on the maximum density and the lowest density, there are aperture level The difference of 10, then we usually say that the tolerance of this film is 10 levels. The concept of latitude points to the fact that if the film’s latitude is at level 10, it means that if you want to express exposure differences of 11 or more levels, your efforts
