THUMBNAIL INDEX

Definition: A thumbnail index can be thought of as a "contact sheet" in traditional photography terms. Most digital cameras allow you to view the images on the storage card in a thumbnail index as an option during playback. Most use a 3 x 3 grid of images, but this does vary between cameras (some even allow you to specify the number of images to be displayed in the index). Often you can still carry out basic functions such as deleting or protecting images while in thumbnail index mode. TIFF: The Tagged-Image File Format (TIFF) is used to exchange files between applications and computer platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. This format of file uses the . tif extension. The TIFF format supports CMYK, RGB, and grayscale files with alpha channels, and Lab, Indexed Colour, and Bitmap files without alpha channels. TIFF also supports LZW compression
