You need to plan ahead if you’re scanning a significant number of high-resolution photographs, or you could potentially run out of storage space. This means the image is captured by the hardware at the hardware’s maximum DPI, then the scanner digitally manipulates the image to add artificial information to the image.Ī note of caution in regard to resolution: the more detailed your image, the larger it will be. The second value listed in a resolution will be the digital resolution. The optical value refers to the maximum number of dots per inch that the scanner can physically capture, based on the hardware. Resolution is subdivided into the optical value and the digital value. If you plan to enlarge the photo, though, you’ll want to use as high a resolution as possible. For the purposes of sharing a photo over email, 300 DPI is sufficient. The lowest resolution setting on a scanner will be adequate for black and white documents, but photographs or detailed images require as high a resolution as possible. The higher the number, the more detail in the scanned image. Resolution is measured in the number of dots per inch (DPI) that the scanner can capture. The most important metric for a scanner is the resolution. The only drawback is that it takes up more room than the compact scanners.
A flatbed scanner is better for dependable, uninterrupted scan results. To contrast, other scanners feed the item past the scanning sensors. Because the item being scanned is stationary, there’s no risk of a sudden movement or mishap blurring the image.
Overview of flatbed scannersĪ flatbed scanner has a flat, glass surface that the item to be scanned is placed on. An embarrassment of scanner riches! The Epson Perfection V39, V19, V370 and V600 filled my home office with more raw scanning potential than I could have ever imagined. But I still was not prepared for the deluge of scanners that showed up at my door for review. So I have discovered the value of having a scanner.
On top of that, there are stacks of family photos in my basement that are gathering dust. So many documents that needed scanning and mailing. Then I bought a house, got insurance, and started doing freelance contract work. As a young man, I never thought I would need a scanner.
