How to adjust the physical camera parameters in VR?

The three most important parameters of VR camera are aperture, shutter and ISO sensitivity.

The larger the aperture parameter, the brighter the scene will be, and even overexposure will occur. On the contrary, the darker the scene will be. Therefore, VR physical camera can be used to improve the brightness of the scene.

The lower the shutter parameter, the brighter the exposure time, and the higher the value, the shorter and darker the exposure time, but if your scene is quite large, you must lower the aperture value.

The larger the film speed parameter, the brighter and darker the scene. Daytime 100-200, 300-400 at night.

Extended data:

The basic principle of the camera is very simple, that is, there is a small hole in a closed area, through which light shines into the photosensitive material (film) to form an image.

The effect of image and the size of hole (hereinafter referred to as hole) are related to the amount of light passing through the hole. The bigger the hole, the more light, the darker the latent image obtained on the photosensitive material (film) and the brighter the final image.

Of course, the brightness of the image is also related to the length of time that the photosensitive material (film) receives light. The longer the light is received, the darker the latent image obtained on the photosensitive material (film) and the brighter the final image.
