Quality - Resolution Matters
The amount of detail in a photograph that a scanner can define is determined by its resolution, its pixels or dots per inch.
A scanner works much like your digital camera does. A bright light shines on the object being scanned. This acts kind of like the flash on a camera. The reflected light passes through specialized lenses and is captured by a digital sensor, where it is turned into pixels.
The word “pixel” is a contraction that means “picture element.” Pixels are the small dots that make up a digital picture.
Higher-resolution digital cameras tend to capture more pixels, which means that they capture more detail.
The same is true of scanners! If a scanner captures more “dots per inch,” it will preserve more of the fine detail in your scanned photos.
Take this image, for example. Here, the photo is scanned at low resolution, which means that relatively few pixels per inch were captured.
Notice how the same photo becomes much more clear when scanned in a medium resolution.
Using a high-resolution setting, even more detail comes into focus. High resolution scanning makes sure that the best-possible quality scans are available for shots that you may want to enlarge or zoom in and crop later.
A quick comparison of popular device displays shows that scanning at 600 dots per inch gives you plenty of pixels to work with, even when the image is displayed on a 30” computer monitor or large HDTV.
E-Z Photo Scan’s practice of scanning at higher resolutions slows down scanner production, but it makes sure that your digital images will have plenty of archival-quality details preserved.
