The clouds in the sky were a bit funky looking, so I chose to go with a 4 min exposure to get them looking a little more interesting. Was also fortunate to have the sun pop up right in between the peaks. Complicated blend consisting of a 4 minute exposure for the sky, one for the sunstar, and a focus stack for the foreground. Whatever compression 500px applies to images really wrecked the white spot in the sky. Unfortunately it got overexposed during the long exposure, and wasn't recoverable in post. Hard to avoid when shooting long exposure straight into the sun. I'm not entirely opposed to it. It's not like we can look straight at the sun with our own eyes and see all the detail around it.
At this point, three days in, I was happy to have learned my lesson about cholla cacti, and was able to avoid them that morning. :)
