DPI and MPs
Nikon produce images at 300dpi, while Canon produce a 72dpi images. How does these 2 outputs differentiate the outcome ? Yahoo Answers :
DPI and Pixel Resolutions are in two different realms, though somewhat related, they are independent. Your camera produces files at the maximum resolution of 4272 x 2848. At 72 dpi, your print will roughly be 60"x40". At 300 dpi, 14.25"x9.493". At 600dpi, 7.12"x4.747", at 1200dpi 3.56"x2.373". Think of cameras in terms of pixel resolution and printers in terms of dpi. When files are inserted into layouts, the embedded dpi value is used. You just need to change the embedded value to match up with the print size you desire. Obviously, if you want a 120"x80" print at 300dpi... you've got the wrong camera. :)
