I digress. The original focus of this post was to talk about how clouds will make a difference in your sunsets. For the people who read my blog, visit my website, or follow me on Facebook, you have probably seen my post from the last sunset. To capture that sunset, I observed what way the clouds were moving in the sky and set up to have the sun and clouds coming straight at me. I wanted to add some drama to separate my sunset from others that I knew were out taking it that evening, so I attached a 10 stop neutral density filter to my lens. This filter cuts 10 stops of light from reaching the sensor, thus giving you a much longer shutter speed. You must use a tripod and remote release for this type of photo since the exposures can last up to 2 minutes. Doing this allows the clouds to move in the frame and give the appearance of moment. I tried this on the sunset last evening also, but the clouds were dissipating quickly and they weren't really moving. I did shoot the sunset with a 6 stop neutral density filter in hopes to catch some cloud movement, but there wasn't much of any. Additionally, the cloud photograph was taken at 12mm since the clouds were moving so rapidly and the stretched far into the frame. The second was taken at 24mm to try and get as much of the clouds in the frame as possible.
Below is the difference between clouds in your photo and without. So the next time you want to shoot a sunset, try for some clouds.
