It's not a fake. I calculated the distance to locate my 80 mm refracting telescope with a Canon EOS 550D attached to catch the castle and the Moon with almost the same angular diameter. I placed the telescope about 6 km from the castle. The trick is only on the brain, the Moon illusion is well know by psychologists and astronomers alike, the brain compares distances between usual objects...but it's not used to compare distances as seen from a scope :-) I used PS to adjust levels on the Moon, but the image hasn’t been photoshoped.

I don't know about the through your legs trick, but yes, it is just your brain screwing with you. When there is the horizon your brain perceives it large than when it is in open space and with nothing to compare it to. You can take your thumb (or another finger if your thumbs are too fat) and holding it at arms length cover the moon up when it is low in the sky. Then do the same thing when it is high in the sky and you will see it is the same size. You can use a ruler as well. If you introduce me to your brother Tom, I will get you a case of gold star stickers. Wow – I was LITERALLY typing the answer when your post showed up.

If I'm correct, do I win a stuffed animal or something?

He's even got a graphic showing the difference between the maximum and minimum apparent size of the moon, which as you'll notice isn't that large. It's just a zoomed in picture - but very nicely executed (he had to calculate where to position himself to get the moonrise behind the castle).

The fact is, the moon ALWAYS looks larger when it sits near the horizon. It is a well-known optical illusion, an happens with any visible celestial body: http://en.wikipedia.org/wiki/Moon_illusion Elliptical orbits and such have a much smaller effect on your perception of the moon's size than tricks your brain plays.

Now, the exposure, however... if the moon were higher in the sky, it would have been so bright that there's no way you'd make out the foreground detail of the castle at the same time.  But since the moon was so near the horizon, its light is traveling through a whole lot more atmosphere at an oblique angle to the surface of the Earth, thus dimming its apparent albedo to the point that its light doesn't overwhelm that of the terrestrial architecture.  So that's why it looks so yellow. I dunno, maybe he manipulated the image a bit, but I don't believe he needed to do so as much as you think he did.
