What does camera sensitivity mean?
Generally speaking, sensitivity is the sensitivity of emulsion on photographic film to light. China standards are GB2 1, GB24, GB27, etc. For every difference of 3 values, the exposure difference is a file. American standards are ISO 100, ISO200, ISO400, etc. Every time the value is doubled, the exposure is one step worse. GB2 1 is equivalent to ISO 100.
When the light is weak and auxiliary lighting (such as flash) is not allowed, improving the sensitivity can get better images.
