What is the resolution of the final scanned image?
Resolution is sometimes referred to in _ pixels by _ pixels. To calculate what your own picture’s resolution will be in pixels, multiply the size in inches by 300 dpi. For example, a 4 inch x 6 inch print will have a resolution of 1200×1800 (4″ x 300dpi = 1200 pixels, 6″x 300dpi = 1800 pixels). 300dpi is suitable for printing a photo of the original size, viewing photos on a TV or projector, and for most other uses. You can upgrade to 600dpi scanning if you plan on enlarging the photos.
