Adsense is Googles easy-to-use ad program which sifts through your sites content and places very relevant ads automatically. Its a great way to earn extra money, since it requires next to no effort to use, and more importantly its free. You can place the ads and start earning right away, but just leaving it like that wont generate much returns. You would have to do a bit of optimizing to get the most out of Googles Adsense.
Many of us do not know the difference between optical and digital zoom. We will try to explain the difference as using the right zoom feature is important for achieving the best photo quality.

Cameras can be held in two positions: horizontal or vertical (also knows as landscape and portrait). Photos taken in the vertical position are later on rotated 90 degrees (either clockwise or counter clockwise). Rotating the photos can be automated if your camera sports an orientation sensor.
