    what does 72 dots per inch really mean?

    my camera is 15 MP. When I upload a photo into Photoshp it says the size is 44 M then gives dimensions and ppi. What if I want to change the image to 300 ppi?

      DPI as DOTS PER INCH (as distinct from PIXELS PER INCH), are the small inkdots (per inch) that come on the paper during the printing-procedure. The DPI (dots/inch) must be larger than the DPI/PPI (pixels/inch), otherwise the result will be a bad print. An example: A print has 300 pixels per inch and 1200 dots per inch. In this case each pixel has the average of 4 (ink)dots. To have a high quality print of an image.
