Metadata is a set of standardized information about a file, such as author name, resolution, color space, copyright, and keywords applied to it. For example, most digital cameras attach some basic information to an image file, such as height, width, file format, and time the image was taken. You can use metadata to streamline your workflow and organize your files.

- We use the term ppi when referring to pixels on a digital camera or display device and dpi when referring to dots in printed output.
- The focal length of the lens is the measure of how “zoomed in” your lens is.
