Formats: TIFF & JPEG
A very simple and quick identification of the two file formats.
TIFF (Tagged Image File Format)
The TIFF format allows for the storage of images and is used predominantly for bitmap data. Colour that is compatible with TIFF’s includes:
· Line art
· Greyscale
· RGB
· CMYK
· YCbCr
· CIELab
TIFF’s use tags in order to declare what type of data follows, such as width or height. They are large in size in comparison to GIF’s or JPEG’s but have the ability to be compressed (loseless – retaining quality). It is said that TIFF’s are more suited to print rather than screen interface.
JPEG (Joint Photographic Experts Group)
The JPEG format is used primarily for the compression of photographic images. Although the file size becomes smaller, the modification of the pixel data means a loss in quality (lossy). JPEG’s may be used in:
· EPS files
· EPS DCS files
· JFIF
· PDF
When a small file is needed for a site or when emailing where maximum quality is not necessarily needed, the format becomes advantageous.
