There are three main files a digital camera uses to store its digital pictures which are JPEG, TIFF, and RAW formats.
The first file format, and the one used in graphic design and photography quite often, is JPEG - a commonly used standard method of compression of images. In fact, the majority of photographers use this as their primary picture mode. A key reason is because it can be used straight out of the camera with no editing, as it is considered a high-quality first use image. It also transfers easily across the Internet, and as email attachments. JPEG/JFIF is the format that is used when pictures are stored and transmitted on the Internet. It is preferably over GIF, which is limited to 256 colors that are not enough for colored photographs, or PNG, what produces larger image files.
The second file format is TIFF which is used for storing images such as line art and photographs, developed by Adobe and Microsoft. A popular format for high color depth images, it is supported by many image-manipulation programs such as Pagemaker, Adobe InDesign, PhotoShop, Paint Shop Pro, etc. It is extremely high in its picture quality, with excellent compatibility with the publishing companies.
The third file format is which is a picture format where the camera has made absolutely no changes; the files are not yet processed or ready to use with an editor, etc. There are not many professional photographers that use this mode. In order for it to be manipulated, the picture needs to be processed and converted to an RGB format that is either TIFF or JPEG. This means that each and every pixel that was captured by the camera is now on the image. The primary advantage is that you can sharpen, size, or crop the picture without losing any picture quality.

In summary, if a photographer wants to keep all the original image data that was recorded, the image must be stored in RAW format. It is the closest thing that will be able to see in a film negative or a transparency that the digital camera can make. |
