   • a photograph. It is recommended that you scan at resolutions from 100-200 dpi.
   • a newspaper. It is recommended that you scan at resolutions from 85-100 dpi.
   • a magazine. It is recommended that you scan at resolutions from 100-150 dpi.
   • a glossy book picture. It is recommended that you scan at resolutions from 100-150 dpi.
   
   
2. a display (or the web). If it is important that the image remains the size you have choosen on a display you need to save your image at the proper dpi. In order to orchestrate this you will need to decide what screen resolution and monitor size you want to view the image on. To calculate the dpi you need take the screens width in pixels and divide by the physical width of the screen in inches. The following table gives examples:
