How long does it take to atomize seawater with long exposure?

During the normal shutter time (generally considered as 1 sec-1/2000s), the exposure time has little effect on the photo, but when the shutter speed is too high, such as110000s, or too low (such as: 30s), the exposure time is limited. This is: reciprocity rate failure, also known as reciprocity rate failure. The specific point is that when the shutter speed is slow, the exposure should be increased appropriately, and the shutter speed is too fast to reduce the exposure. Only in this way can the standard exposure be guaranteed. As for the influence, long exposure will increase the haze of the film, and short exposure will increase the contrast of the film.
