Is ISO 100 really suitable for concert stage photography?

Whether it works or not depends on what the photographer wants to shoot:

1 and iso are used together with aperture and shutter;

2. How much iso to use depends on the photographer's creative intention:

Assuming that the stage lighting is good, iso 100 is of course possible to ensure the clarity of photos on the premise of combining aperture and shutter.

On the other hand, the stage lighting is not very good. On the premise of combining aperture and shutter, the photos taken by iso 100 will be weak, but it is also a good choice for photographers to take a film that combines static and dynamic stage actors, or even take a drag. At the same time, in this case, if the film made by iso 100 is in a mess, even if the aperture shutter is adjusted, the desired effect will not be achieved, which means that using iso 100 in this scene is a failure.

3. Therefore, the shooting parameters are not fixed, mainly according to the intention of the creator photographer, the combination of iso value, aperture value and shutter value is flexibly changed, and the final shooting effect is achieved.
