One of my favorite sunrise photos from our trip to Death Valley is this image of a... what, tree? shrub? bush? silhouetted against the morning sky at Mesquite Dunes. I love the smooth curves of the sand in the foreground, the similar sweep of clouds in the background, with just a hint of color from the not-yet-risen sun, and that solitary plant clinging to life at the top of the dunes. I took several versions of the photo, shooting fast while the light held; this one's my personal favorite. I shot RAW, so I could adjust the exposure; truth be told, I'm still fiddling with it, experimenting with different settings. What do you think?
