Scanning
From FCTL eLearning Wiki
The Faculty Workroom in IRC 122 has two color scanners for faculty to use for scanning documents and images.

Tips
- Know about file types, there are different file types which should be used for different purposes.
- If you are scanning to use images on the web or in FerrisConnect, you need to use a file type that is recognizable by the computers your audience is using. Additionally, you will want to keep the file size small so that the images download in a reasonable time. JPEG and GIF file formats are good choices.
- If you are going to share the images via a DVD or CD and file size is not an issue, save your images as TIFF files which do not compress the image data.
- Resolution: If you're scanning for a Web page and will never use the scan for anything else, scan at 75 to 100 dpi. If you are scanning for a photo-quality print, scan at 300 or 600 dpi. If you are scanning for archival purposes (to have a copy of an important item, for example), scan at the highest optical resolution your scanner can manage.
- If you are scanning a document or photograph that you might use for multiple purposes, you can always scan it in with a high dpi and keep an original copy of the file for archival purposes because you can always optimize a scanned file later to a lower dpi, lower quality, smaller file size, but you cannot go from a low quality, low resolution file and increase the quality or resolution.
- Image File Formats - TIF, JPG, PNG, GIF: Which to use?
