Especially for pre-dawn photos you'll leave home while it's still dark. Knowing what you're going to shoot and how to get there is vital. You'll need a flashlight or headlamp as often as not. After sunset you'll need the flash to get back.

This was a 15 minute hike and required setting up before real light. It's still 5 - 10 minutes before official sunrise.
Knowing not only the time of sunrise but what where the sun comes up is very helpful. Most shots are done towards the sun but shooting away also gives wonderful light.

Most pre-dawn shots are landscapes but having people in the frame can add something.

We both scrambled over rocks with headlights to get where we wanted to be.
