3: Know your camera inside out
Again, you’ll be shooting mostly in the dark, so being able to change your shutter speed, aperture, ISO, focal length, focus modes etc without looking is going to save you untold amounts of time and stress!
4: Shoot multiple exposures
Sunrise scenes are full of contrast with the bright sun creating the darkest shadows across the scene. Even as camera processors improve and are able to record wider and wider dynamic ranges in one shot, some scenes will ALWAYS be too much for any camera to capture in one. This means that you’ll either end up with over exposed highlights or under exposed shadows, both of which are not good if you want to produce the best possible sunrise photo.
So shoot multiple bracketed exposures to capture the entire dynamic range across as many exposures as you need. Then you’ll be able to combine them into one high dynamic range shot in Photoshop later.
