File Types, Sizes & Uses

Unlike film, where the same transparency could be used in different situations, digital files are usually made for specific uses.

The common file types are "tiff" (or .tif) and "jpeg" (or .jpg). Under normal conditions, we deliver images to our clients as 50mb RGB tiffs and 1mb jpegs.

The much larger (and therefore higher-resolution) tiff file is used for making photo-quality prints or for taking an image to press for printing. Because of their size, tiff files cannot be easily emailed and may be difficult to open on computers with limited memory.

The much smaller jpeg files are easy to email, they look good on a computer monitor, and therefore can be used on your web site.
