First taken 2 pictures as below,
Then, croping the second picture (eagle picture) and zoom it out to maximum, but becareful when you crop and zoom, because too much of zooming will cause the eagle to become blur.
Well, for your information, I crop the eagle picture using Paint.NET (Freeware).
Then, adjusting the the sky color to match up with the first picture. So, the eagle picture I randomly place it and by using Photoshop CS3 to matching up the color for eagle picture with the first picture sky color.
So, there you go... the outcome...
Happy Photochopping... :)
