Silhouettes are quite powerful. Here is another of my favorites. This was taken about 20 minutes before sunrise in Lakeport which is a small town on Clearlake CA
Nothing fancy. Long exposure, so I used the mode on camera that reduces sensor noise by taking two exposures. One with the shutter open and one with the shutter closed. It then subtracts the noise from the shutter closed image (eliminating hot pixels) from the one with the shutter open. Surprising how effective the process is. There is little noise in this image and it was about a 30 second exposure!
