Night Hike!
Full moon, so we decided to do a night hike. We did this hike the week before and decided it is a perfect candidate for a night hike. It was a bit cloudy, so we did need to use the head lamps at times, especially when in the shadows of the Superstitions.

A bit of information on the photos, because I have noticed when posting night photos that some folks don't believe they are night photos. This is how I do it.. I take along a tripod, and setup the camera for HDR. This takes three photos that are eventually combined to form one photo. The first photo is regular exposure, followed by under exposed photo and finally an over exposed photos. Combining the three together provides for a fuller dynamic range, so you can see the shadows better. The lens I used for these photos is the Rokinon 14mm f2.8, known by astronomers a a great night scenery lens. I have it set at f4 for these photos. The camera is a Canon 5D MIV. Settings on the camera is ISO 1000, 3 stops +/-2.5 with noise reduction. When I take a photo, the exposure times are generally 13", 2.5" and 30".

So why is the sky blue in the photos, but not when you look at night? I discovered as an amateur astronomer that the eye requires a threshold of light before it is able to distinguish colors. Rods are very sensitive to light, but cannot distinguish color while the Cones are not so sensitive to light and can distinguish the color. So even though the moon may be full, the sky does not look blue, and the landscape appears gray.
