Rf stock photo意思
"RF" in "RF stock photo" stands for "Royalty-Free." A royalty-free stock photo is an image that is sold with the right to use it multiple times without having to pay additional fees each time it is used. This is in contrast to rights-managed stock photos, where the buyer pays a fee each time the image is used, or exclusive stock photos, which are only available to one buyer.
Royalty-free stock photos are widely used by businesses, individuals, and media organizations for a variety of purposes, including advertising, marketing, web design, and print publications. They are available from a variety of sources, including stock photo agencies, individual photographers, and online marketplaces.
