There are endless possibilities when you scan your photo for prints. Some people think they are only saving themselves a digital copy “just in case.” You can do lots of things like converting old pictures to digital image and doing digital imaging and restoration. You can also share it via e-mail or online in social networking sites, and make new and bigger prints.

When doing photo scanning, you need to familiarize yourself with common scanning terms like scanner resolution, dpi and ppi, and file format. While these may seem alien to you, these are terms that you will likely encounter when performing the task. Scanner resolution is measured in either pixels per inch (ppi) or dots per inch (dpi). Dpi is used to describe print quality, while ppi refers to the digital image itself. In essence, scanners measure resolution in terms of ppi, while HP printers and all-in-one units use dpi when referring to print quality.

Photo scanning are saved in different formats, found at the extensions at the end of the filename (.jpg, .jpeg, .gif or .tif). When choosing the resolution, resolution and image quality go hand in hand, so the more dots/pixels per inch in your photo, the more detail you will see. However, you should not always scan in high resolution as the higher the resolution, the image file size also increases. Smaller files with a resolution of 75 to 100 ppi are appropriate to send via e-mail, while 300 ppi is sufficient for printing.
