In the days before digital it was darned hard to do night shots as an amateur. Flash won’t light the Eiffel Tower. You used the film that was in the camera. Lights are bright but will not be sufficient to light up everything in your picture. Digital makes hash of all of that worry. The mini computer can compensate on the fly. ISO adjusts automatically as the light changes. The processor will adapt to artificial light.
Then – You accept noise in your image. Basically, you are thankful for a shot. Now – The shots are so exceptionally better that you don’t realize how easy it all is today. I’m amazed. I take it in stride and even shot the stars (recently) in the night sky without a tripod. I’m not bragging. I can only say that you can push the envelope and it often will give you something better than expected.
