General Thoughts on Photographing Maui:

• Maui is closer to the equator than the continental United States, so sunset will likely be between 6 and 7pm (check the local times with you hotel or a dive shop).
• Try different locations at different times of day, as the site will look vastly different at 6:30pm than it did at 11am.
• Locals will be out at the beaches on the weekends (it's their days off), so expect there to be more crowds during this time.
• Sunrise at Haleakala is the best time for photographing because there is less likelihood of clouds obscuring your views of the crater and valleys below.
• Mornings are much calmer, and afternoons are more windy, so plan accordingly.
• If you want to do a lot of photographing on the Road to Hana, get a really early start to avoid the crowds. Even better, if you can, spend a night in Hana and you'll likely have the Seven Sacred Pools all to yourself early in the morning. By mid-to-late morning, the early-bird day-trip drivers will have reached that point of the drive and be out swimming or taking photographs themselves.
• Respect all private property and don't trespass. If something is marked at "kapu" that means "keep out" or "forbidden", please respect this and don't try to enter for any reason without owner's specific permission.
• Always carry extra compact flash (or film) and extra batteries, you'll need them.
• Tripods are useful if you can mange to carry one around. Even a small one will help you get a steadier shot at sunset.
• Try different angles and viewpoints.
• Look around at local galleries for inspiration!
• Always carry water when trekking around for the best location to get your shot.
