What is the best picture quality when the aperture shutter ISO is set in the studio?

Are you talking about digital machines? Generally speaking, the lower the iso, the better. For example, iso 100 or even 50. Nikon d700 has ultra-low 2nd gear. The aperture is related to the lens, usually the smaller the better. Of course, the maximum aperture of some lenses is good. For example, Zeiss g head.

Use a smaller lens in Japan.

The faster the shutter, the better. The longer the time, the louder the noise.

Because these three factors are all low sensitivity, it is decided that there should be enough light on the scene, otherwise it will be underexposed.
