What does 10,000 exposures mean?

Ten thousand exposures are camera parameters.

Exposure is simply the total amount of light entering the camera. The amount of light entering the camera is determined by the aperture size and shutter speed of the camera. The larger the aperture, the lower the shutter speed, and the more light enters the camera. Exposure determines the brightness of a photo. The greater the exposure, the brighter the photo; Conversely, the smaller the exposure, the darker the photo. Overexposure, the photo looks very white, and many details of the subject will be lost; If the exposure is too small and the photo is underexposed, the main details will be submerged in the darkness. Only the correct exposure can show the true colors of the subject.

In photography, exposure value represents all camera aperture shutter combinations that can give the same exposure. Exposure value 0 corresponds to the combination of exposure time 1 sec and aperture f/ 1.0 or its equivalent combination. If the exposure value has been determined, then the combination of exposure time and aperture can be selected according to it. Every time the exposure value increases 1, the exposure will change by one step, that is, the exposure will be halved, for example, the exposure time or aperture area will be halved. This may cause confusion. The reason for the decrease, rather than the increase, is that the exposure value reflects the setting of camera shooting parameters, rather than the illumination of the film.
