dpi (Dots per inch) Explained. dpi, ppi, dots per inch, points per inch, lines per inch, these are confusing for designers and photographers and printers alike. Here I attempt to explain what it means and if your camera has enough megapixels to handle it. Your camera uses pixels, the printer prints in dots, You can think of them as the same thing, they are singular points of color data. If you have a 1in x 1in image at 100 dpi, how many dots do you have in that inch? 10,000 total dots. Simple right? So how many dots in a 42 mega pixel sensor? 42,000,000 of course. PRINT RESOLUTION billboards = 15 dpi Screens = 72-100dpi Magazine = 150dpi Fine art print = 240dpi Retina Screen = 300dpi Website: http://www.kuohphotography.com/ Instagram: https://www.instagram.com/kuohphotography/
