Thank you all for the great input. I created the thread out of curiosity, and I can now leave satisfied. This is what makes ATS such a great place. Thanks again, I appreciate all of you taking the time to explain what is happening in this photo.

Cheers,
Strype

Good investigating Chad


But how did the sun get that freaking big? If i compare it to any given sunrise i have seen on my part of the hemisphere i can't say i have ever seen it that big. (taken into account of course that "big" is pretty relative but if i compare it to surrounding structures in the pic. it still seems bigger then any sun i've ever seen.)

Peace and respect.


You use a lens longer than 2000 mm in focal length. Distance is compressed and distant objects like the sun and moon become larger than life. As a photographer for 40 years, I can say that picture could not have been taken with an 80mm lens. The sun and moon would be much, much, smaller.....Or it has been PHOTOSHOPPED.

No way is that 2000mm.

When was the last time you saw a 2000mm lens for sale?

Probably an 800mm, and someone left out a "0" in the description.


Edit to add:

A 2000mm lens would have a horizontal field of view of 0.8 degrees. You can check this yourself by plugging in the focal length here.

The Sun and Moon measure about 0.5 degrees, so almost the full frame would be taken up by the Moon in the horizontal direction with a 2000mm lens.

Using the calculator I linked to above, and plugging in 800mm gives a horizontal field of view of 2.3 degrees, or a bit under 5 times the width of the Sun/Moon, which works out about right for the picture if you take into account that the atmosphere distorts our view of the Sun/Moon, making them appear "squashed" when they are this low on the horizon.
