Say when you took a 6MP picture with your DC. Upon viewing it on your PC, you feel that the subject is small and decided to make it looks bigger by cropping the entire picture to a smaller size (say 2MP).
In this way, the subject will be bigger on a 4R print and the picture still look sharp since 2MP is sufficient for a 4R print.
How different is this method compared to optical zooming?
