This workshop will focus on scanning opaque and transparent images using scanners available in the Educational Technology Center. The end-use of any given image will determine what scanner you should use, and what settings you will specify for the equipment. Pixels are the basic building blocks of a digital image.
Pixel content is controlled by input resolution.
Scanning allows you to create TIFF, JPEG and GIF files. TIFF files are flexible, uncompressed, large format files which retain the highest degree of visual data from your original analog image. Generally, you will compress TIFF files as JPEGs or GIFs for Web use. You should pre-determine digital targets for output and scan to the largest needed output size. You should not sample-up from a smaller file size to a larger one.
