\"Old-Photographs\"<\/p>\n

If you\u2019ve recently unearthed a huge stack of old family photos and want to scan them, that\u2019s a great decision. Sending original photos to a scanning service is one hassle-free option to digitize your favorite photos and preserve<\/a> them for generations. But the prospect of doing so can be a little overwhelming for first-time scanners. This leads to procrastination. And that\u2019s not a good thing because old photos<\/a> are subject to deterioration and scanning should be done as soon as possible. Digitizing photos is crucial to prevent deterioration and loss, and it also helps in organizing and storing the digitized photos. Before you undertake DIY scanning<\/a>, it helps to understand the basic terminology that plays an integral role in both the quality of scans and the ability to create nice new prints.<\/p>\n

Pixels, DPI, Resolution, and Image Quality<\/h2>\n
\n

Understanding Pixels<\/h3>\n

All digital objects are composed of pixels, while printed images consist of dots. Simply put, a pixel (also called picture element) is the smallest unit of any digital image or graphic. Together, they form any visible format on an electronic display. The greater the number of pixels per inch, the better the image quality.<\/p>\n

If you zoom in on an image, you\u2019ll start to see the pixels. These colored squares may remind you of that Lite-Brite game from your childhood. When you can see the pixels in an image, this is referred to as pixelated. And this isn\u2019t considered a desirable element in digital or printed photos, unless you\u2019re an artist creating this effect on purpose.<\/p>\n

Enhancing Image Quality<\/h3>\n

Using photo editing software like Adobe Photoshop will enhance your digital photos by offering advanced editing options such as colorizing black-and-white photos, restoring images, and correcting color, crease lines, and red-eye.<\/p>\n

DPI:<\/strong> Dots Per Inch<\/h3>\n

Short for dots per inch, this term applies to printed images, however, most people also use it for digital images. DPI uses the CMYK (cyan, magenta, yellow, and key\/black) color model to determine the amount of red, green, and blue light reflected from white. If you intend to print your digital images, you need to pay close attention to the DPI.<\/p>\n

The best DPI for scanning photos<\/a> depends on your intentions. If the image will be displayed on a website only, 72 to 96 DPI should suffice. But if you wish to create new prints, you need to save the image with a minimum DPI of 300 and boost this to at least 600 to make enlargements.<\/p>\n

PPI: Pixels Per Inch<\/strong><\/h3>\n

Short for pixels per inch, you may not have heard of this term because it\u2019s used primarily by design and printing professionals. Just like DPI, the number of pixels per inch determines image resolution. PPI utilizes the RGB (red, green, and blue) color model reserved for electronic display of images. This additive color process blends these colors into a single hue at the pixel level.<\/p>\n

Tip for Improving Scan Quality<\/h3>\n

To improve the quality of your photo scans, ensure that the scanner glass and photos are clean and free of dust.<\/p>\n<\/div>\n

The Scanning Process<\/h3>\n

To digitize old photos, remember that each image made of dots is converted into pixels (squares). If you looked at a vintage comic book from your childhood, you could easily see the dots and these would get picked up if you scanned one of the pages. That\u2019s because old comic books were generally printed inexpensively with low resolution. Pixels and DPI are the two elements that comprise photo scan resolution<\/a>. If you wish to increase picture resolution, you need to increase the number of pixels and the DPI to get the best resolution. Here\u2019s an example to better illustrate this principle:<\/p>\n
