This chapter covered many issues concerning file formats. Some of the key points included the following:

■ The file format you use for shooting and saving your photos will directly impact image quality, speed, convenience, and compatibility.

■ JPEG is the one format used in all digital cameras, and it has become the most common photo and imaging format for all kinds of projects.

■ TIFF is the highest-quality digital camera format that any computer, program, or printer can read without special software.

■ RAW files offer the very highest image quality, combined with faster shooting speeds and smaller file sizes (compared to TIFF). They do this by postponing all processing until the file is uploaded to the computer.

■ Metadata is information about your photo that is stored within the photo file. From it, you can learn a lot about the conditions, camera, and settings that were used to take a photo.
