Clouds and rays
Sunsets which appear to be very dramatic to your naked eye may not be so dramatic as seen by your camera's sensor. Your sensor is not in the same league with your eyes by a long shot when it comes to capturing visual information.
When we apply a bit of manipulation and enhance the picture, we get the image closer to what we saw. I underexposed this picture to avoid blown out highlights, so I had to selectively put the brightness and color back in to achieve an appearance which looks more like the real thing.
