My question is this. The majority of pictures that I take I either crop in photoshop to send via email, or just crop them to a smaller size so I can print them out as 4x6 pics on the Kodak photo center machine at my nearest CVS or Walgreens.
So, if I use a smaller MegaPixel setting when I take pictures, like a 1.8 or 3.1 MP, am I ruining the quality of the picture by using less MP's??? I guess another good question, (since I don't know...what exactly do megapixels do for a camera/pictures?
Any info/advice would be very much appreciated. Gracias.
