How to measure light with digital camera in film photography

Find a camera that can manually adjust the aperture shutter ISO. ISO is set to the ISO of your movie. Adjust the shutter aperture to take the photo you want, and then adjust the film camera according to the aperture of this photo and shoot it. Of course, the ISO of a film camera is determined by the film.

As a reminder, some digital cameras have ISO virtual standards, and the exposure of the same parameters is very different.

Nikon or Canon digital cameras are recommended.
