Find the Hidden Image

So I was reading a photography magazine today and thought about this image that I saw awhile back. So here is the question for you:

There is an image hidden within this image (watermark included), can you figure out what it is?

I'll post the answer below in white so that it doesn't spoil it. As well as the link that will explain it a bit more. If anyone can get it right, they might get a special prize.

Also, I worked on a print this weekend, photos coming soon.

Answer: The NYC skyline. It is hidden in the histogram for the image, open it in photoshop and see.
