What is the difference between the dpi resolutions?
If you want to view the photos on the computer, share them over the internet, print the photo at its original size or make a photo slideshow, 300 dpi is the standard setting.
If you want to print the photo up to double its original size, you may want to consider 600 dpi.
If you plan to do significant cropping on the images, or plan to print the photo up to four times its original size, you may want to consider 1200dpi.
