Step exposure method

"Step exposure" is also called "bracket exposure" and "addition and subtraction exposure", which means shooting the same subject with several different exposures. Usually, one photo is taken according to the estimated exposure, and then the exposure is increased and decreased respectively. If it is estimated to be 1/30 and f4, shoot again with 1/30, f8 and 1/30 and f5.6 Whether the interval between increasing and decreasing exposure is one step or half step, shooting in groups of three or five, and so on. , you can decide according to your own grasp of correct exposure and requirements for exposure accuracy.

This step exposure method is not only a practical method to ensure a better picture when estimating exposure; Moreover, when determining the exposure with the exposure meter, it is also a practical method to ensure the high accuracy of exposure.

Therefore, the step-by-step exposure method has important practical value for both ordinary photographers and experienced photographers. Of course, this method will cost you more film, but it will bring you success.
