You can shoot right after selecting an

Higher ISO speeds increase image noise. To take clean
images, use as low an ISO speed as possible.

will automatically raise the speed when the shooting
condition limits are reached. It will also raise the speed
when the light from the flash is insufficient to illuminate
the subject matter.
