Today was the first day in the Smoky Mountains in about a year. I set the alarm clock for 3:00am to drive to Clingman's Dome for sunrise and to scout it out for Astral Photography (later this week). When I arrived I found it to be less than desirable. In fact, it was downright bad. I could see about 30 feet with no break in the clouds. Based on that I started my way down and decided to try a few places I knew about. I was fortunate that Clingman's was the only place fully engulfed in clouds. During my decent I also came across a coyote and a black bear. It was a treat for me. However, you will not see any images of those critters because it was just too dark to bring back some shots. The remainder of the trip was pleasant and as you can tell the mountains did cooperate a bit. I am heading back out the Wednesday weather permitting. All the editing you see here is being done on my small laptop so full edited versions will be seen after we get back to South Florida.
I started into photography prior to the digital revolution. I spent time in the traditional wet darkroom (hours and hours). I then moved onto slide film and sent the work off to be processed. Then along came the scanners and hours in early Photoshop removing dust. Don’t forget the tone curve and how important that was. 

One of the first questions I get asked when people look at my photographs is “did you do something to it in Photoshop?” The answer is always going to be yes (well, at least Lightroom). Why? Well, I shoot in RAW. RAW captures the most data when taking photos but leaves the photos looking “flat”. This is because the camera has made no color or contrast decisions for you. When you shoot JPEG the camera makes all the color decisions based on certain algorithms and what it thinks you are going for. You could say that ALL images go through color changes or contrast adjustments. Some the photographer has creative control over and others the camera has the control. I prefer to control this on my own using the RAW format. 
For example, the two images above were taken in a standard hotel. The first in the room where the bride was getting ready and the second in the lobby. These were not spectacular locations but it is what we had to work with.
