I live in Arizona, there's not much but desert. But if you're in the right place at the right time, it can look amazing. These are from South Mountain between 4am-10am. Taken with a Nikon D90 I have a whole lot of photography, they're typically high resolution, if you want more, let me know. Sorry about the 4k x 2k pictures , next time i will be sure to resize them for you guys .
It looks like you're getting a lot of artifacts in your shadows. Make sure you iso isn't set too high!
played with the first one for a few minutes. nothing major just colors and whatnot, thought i would share. http://img543.imageshack.us/img543/7909/64530740.png
