I got this photo of the Fountain on Wednesday evening. There are two photos here, but they’re the same except for some tweaks to the hue and saturation of the orange colors from the sky.
I went to the Fountain Lake on Tuesday evening, hoping to get a shot of the Fountain at sunset. I got a shot, but the sunset was unremarkable. I waited around until the 7:00pm Fountain and got a very different shot entirely.
I took this photo of these trees roughly 10 minutes after sunset.
This is the 7:00pm Fountain, taken over an hour after sunset.
As I was walking around the Fountain Lake to return to my car, I noticed another good spot from which to take a Fountain photo in the future. I took a test shot and was surprised at the result. This is a 20 second exposure, taken at f/4.5, ISO 640. I was amazed at the color of the sky. It was quite dark by this time. I could make out a glow in the sky to the left, but it was quite a lot darker. I could also see the saguaros and their shadows on the water, but none of the detail on their grassy island.
