Answer:
TIFF
Explanation:
Sometimes the quality and resolution is very important, especially in commercial work. A non-compressed lossless file format is required. This is the format used by professionals in the publishing, graphics and printing industry. Since TIFF (Tagged Image File Format) is not compressed, it preserves more quality at the highest resolution, but require more disk space for storage. Since they are huge, sending them over slow Internet connections would not be a good idea unless they can be zipped or sent as a compressed file.
