Scanning Images The way that scanners are hooked up to computers are slightly different across campus. Choose a location below to read detailed instructions on how to scan a physical object into an editable digital file. Most photographs used on the college web site were scanned from photographs or slides using equipment in a computing lab. The slide scanner can scan either slides or negatives, and the flatbed scanners can scan anything that fits on the glass, including drawings, photographs, your hand, etc. If you are expert enough to want high-resolution scans or more realistic tone in your black-and-white images, there are several good books on importing artwork into the digital world using scanners. If you have a specific questions, please ask us. If you've gone through the trouble to hike to a computing lab to scan your photos, save them in an uncompressed format so that if you need a bigger/better digital image later, you won't have to re-scan. TIFF is a good cross-platform image format; as soon as your scan drops into Photoshop, save as TIFF. You can then modify the image and save as a GIF or JPEG. For more help on image formats or on compression, see the Handbook page on Images. For more information about resolution, and what 72 ppi means, see an explanation of screen resolution.
