This is one very beautiful picture. You keep coming up with them; this is the second one I've seen tonight. But I don't understand why the image of the sun is so large...Can you explain it? Absolutely gorgeous.
Thank you!

2. It looks computer generated. |
|
but if it is a real picture, then they have a really good zoom.

3. That makes a lot of sense. |
|
I would expect computer generated. But maybe a helluva zoom would do it, also.
Thanks for answering! I have a lot to learn still about digital photography....

4. And the technical reason |
|
From the National Weather Service, more correctly a chasers site.
Photographs of the sun taken close to the horizon at sunrise and sunset and high in the sky around noon showed that the sun is not larger when it is close to the horizon. Most people agree that we think it is larger because there are many objects close to the horizon (houses etc.) with which we can compare the image of the sun, but we cannot do this when the sun is high up in the sky. By the way, the same effect also occurs with the moon. Furthermore, close to the horizon the images of the sun and the moon are distorted by the Earth's atmosphere. They are not round anymore but tend to be compressed in the vertical direction. This might be an additional factor that makes us think that the sun and the moon look larger close to the horizon.
