With the evolution of digital technology, it's normal to expect pictures that are in mega-pixels of resolution. In fact, today's handheld devices have megapixel (MP) cameras, and probably even the low-end devices come with upwards of 1MP.

Here, you can find truly high-definition panoramic pictures that take photography to a new level.
PS: There's some interesting stuff in some of the pics there - and you'll have to observe closely to figure out if it's believable or indeed incredible!
