This one is from the previous morning to my whale with moon image.
Both images were captured with a new Canon 5D III and a 70-200 f/2.8 with a 2x converter. This image was at 400mm, f/5.6 with a shutter speed of 1/2500 of a second at ISO 640. That was more then enough shutter speed, I could have dropped my ISO or gone to f/8. As the sun peaks above the mountains in the morning, the amount of available light changes rapidly.
