I have noticed that ALL of my Nikon cameras - from P&S to D200 - produce files with 300 pixels per inch resolution. My son's Canon A620 produces files with 180 pixels per inch. If you crop a full frame from either camera to any matching print size, the resulting pixels per inch will be close to the same thing.
Another way to look at this: The Canon image is nominally 6 MP at 3072 x 2304 pixels. At 180 pixels per inch, the resulting full format print would be 17.067" x 12.8". The Nikon D70s "6 MP" image is 3008 x 2000 pixels, but the resulting full format print would only be 10.027" x 6.667". If I crop the full frame of the Canon image to 10" x 6.67", I lose a bit of the full image, but the resulting image will be 307.2 pixels per inch resolution.
Can anyone help educate me here? Why did Nikon choose 300 pix/in and Canon 180 pix/in? When it comes down to it, is the Nikon image really higher resolution?
Thanks.
