This was a crystal clear dawn at Monument Valley Navajo
Tribal Park in Utah. We had walked a short distance from our cars in the deep
pre-dawn darkness, trekking over uneven sand and narrowly missing a sleeping
and lethargic (thank goodness) rattlesnake.
This is a magical place at any time of day, but at sunrise
it is especially spectacular. In the darkness when we arrived, virtually
nothing was visible beyond the range of our flashlights. As the sky slowly
lightened, dark shapes began to form all around us, like sleeping giants waking
for the day.
Our Navajo Indian guide knew the area well, and skillfully
guided us to just the right vantage point for sunrise. We set up our tripods in
total darkness, made some preliminary camera settings, and waited.
Sure enough, right on schedule, the sun began to appear on
the horizon. At sunrise the sun moves very rapidly and you have to be ready to
shoot quickly. You have just a few
minutes before it is completely above the horizon and the light level changes
radically.
My preference is to shoot sunrise before the sun even
appears, and then again when it is just breaking the horizon. In this shot it
had just cleared the horizon, but I was able to position myself so that the sun was
partially blocked by the “totem” formation, causing the appearance of a
starburst on the rock face itself.
You can create a natural starburst easily by using a small
aperture (f/16 or f/22 or smaller). As long as it is not too hazy and there is
something solid between you and the partially visible sun, like a rocky
outcrop, a building, or even the horizon, the starburst will appear all by
itself.
Exposure at sunrise is relatively easy. I generally want
rich color in the sky, and expose for that. It is fine for the foreground, in
this case the rocks, to be silhouetted and without detail. As always, be sure
to check the histogram every few shots since the light levels rise very quickly
at sunrise.
Note that the sun is so bright that it will rarely have any
color in the brightest area. As long as the other elements in the scene are
interesting and have color, the pure white area of the sun is not a problem.
Focus is the other dicey thing at sunrise. I prefer to use
autofocus, and try to find the edge of something dark like a rock or a tree against the
slightly lighter sky to focus on. Look for a line between the dark foreground
and the lighter sky to aim at. That will help the autofocus mechanism find
something to grab on to. Live View is rarely helpful in very low light and I do
not use it.
