And remember you are photographing flashes of light. ISO 400 F22 bulb, ISO 200 F16 bulb , ISO 100 F11 bulb. You don't have to use bulb but it gives you better control, you can just set it for 10, 20 or 30 sec. but bulb allows you to stop the picture at a good point. Been photographing fireworks since 1976 and will guaranteed the exposure settings.
Thank you. I plan to use bulb and will dial in ISO 100, f11.
