Ghost Birds

Early this evening, maybe 20-30 minutes after the official sunset time for our area, I heard the tell-tale low honk of trumpeter swans. It took some looking to find the source since all I could see were faint outlines/silhouettes on the edge of reflected sunset on the river. To possibly record images I pushed my ISO setting on my camera quite high. The files straight out of the camera were almost unusable. However, by applying noise reduction I was able to salvage at least one image. Without noise reduction, no photo would be seen here.
