I never intended to take pictures of a storm when I decided to visit this location. I was hoping for a fiery sky with some interesting clouds. When I got there, I saw this massive front in the distance. For the first and third shots, I believe that I used a tripod, and the second shot was hand held. Early on I was trying to get some foreground in my shots, so I was using a smaller aperture and needed the tripod. I quickly realized that the location didn't have much to offer concerning the foreground, so I took the camera off the tripod and shot with a wider aperture.
As a rule, I pretty much always shoot raw. Concerning the conversion and editing, I used Adobe Camera Raw to make some adjustments but nothing to do with black and white conversion. To convert these, all I used was the black and white converter tool in PS6. I also did some dodging and burning of the clouds.
