What is the difference between scanning DPI and megapixels?
That’s a great question! Digital images are comprised of millions of tiny little color dots, or pixels, that together form a picture. Essentially, scanning DPI tells you how many dots there are in every inch. The more dots, the sharper the image appears. When you scan a 4×6 picture at 300 DPI (dots per inch), the resulting digital image measures 1200×1800 pixels. Multiplying the length and width gives you the full amount of pixels in the image — in this case 2.16 million pixels, or just over 2 megapixels. While this may sound low compared to the latest digital cameras, with scanners you never have to worry about having proper focus or avoiding reflections. The results are always sharp, in focus and cropped correctly. If you require higher resolution scans, a 600DPI scan of a 4×6 photo will result in nearly a 9MP (2400×3600) image. The amount of pixels, measured in megapixels, will depend on the size of your original print and the DPI used to scan. The different terminology can be conf
