I can't tell if the first picture is an example of tilt-shift photography or not. In either case it is awesome so I snatched it off a stock site to create this wallpaper. Just did some cropping, no other tweaking done. The colours on the second one caught my eye. I looked at the description of where the picture was taken from and provided you with the link below. Full size of each 1920 x 1200.
For those that don't have that resolution don't worry, you can right-click, save and when you open it up as a background, select stretch instead of center and the entire calendar will show.
