This was actually just the start of my evening (even though its sunset). This was taken on a hike through Sugarloaf State Park. I was up there for an event at the Robert Ferguson Observatory that night. If you are near Santa Rosa I would highly recommend going up there for one of their events. Public events are only once a week but they are totally worth it. I digress, the hiking in this park is amazing too. There are some trails closed because of the fire a few months ago but the ones that are open are enjoyable.
Sunsets are one of my favorite things to capture, but a sunset in the mountains is on the top no doubt. What I try to do when getting a mountain sunset is make sure I have a good depth of field. I really love that look when the hills start turning blue and fade off into the distance. Its just a personal preference, but I think its what makes these shots so stunning.
