I shot this image with my new Sigma 150-600 sport lens. I had to pump up the ISO higher than I wanted to keep the shutter speed fast enough to get a sharp image. Even with the high ISO the RAW image was almost completely black. This was taken well after sunset. I wasn't even sure if the images were going to be usable or not. I was able to basically recover everything and I was surprised at the images I was able to capture. The light was perfect and pelican was moving around in a way to get some very interesting silhouettes. Then after running this through Topaz denoise I got a better result than I was really expecting. I also like how the clouds in the background look almost like mountains.
