Why Does It Matter What File Format I

The file format—the manner in which image data are organized—defines exactly how a photo is constructed. To use the cooking analogy again, we can make spaghetti sauce by opening a can, pouring the contents into a container, and shoving it in the microwave. Or, we can select juicy ripe tomatoes, basil, onions, garlic, oregano, sweet peppers, and other farm fresh ingredients; chop them; saute the mixture in extra virgin olive oil and fine wine; and then simmer it for hours on the stove.

Both sauces will be tasty, and both can be called spaghetti sauce. But the homemade one will definitely have a deeper, more abundant flavor and richer texture than the microwaved prepackaged version.

Still, isn't it wonderful that we live in the modern world in which we can simply open a can and use the microwave to quickly put together an enjoyable meal? No, it isn't gourmet, but sometimes you don't really want, need, or have the time and budget for gourmet.

Some file formats create and preserve higher-quality image data, with greater tonality, texture, and detail. But there's always a tradeoff—in time, convenience, size, and ease of use. For that reason, it is best to understand the pros and cons of each file format, so you may make informed decisions about which one you'll use to save your images.

Your choice of digital camera file format will influence:

■ Image quality

■ How fast you can take your pictures

■ Your ability to use them on the Web, in email, or in print

■ Your storage capacity and convenience

■ Your ability to open, edit, and view your photos on a computer

■ How easily (if at all) you can share your photos with a third party, such as a client or art director The following section will help you make intelligent decisions about file formats.
