I was recently reading a wikipedia article on what is the difference between the DPI (dots per inch) and PPI (pixels per inch). I've came up to the point that the DPI value is relevant for the printer and the PPI value is relevant for the monitor.
As I'm not even a hobbyist photographer, I wonder, if a single image can store both DPI and PPI in the image's metadata? (so i.e. the picture would have different physical dimensions (in inches) on a monitor and when printed). Is this a common practice with pictures?
