Usually, paying for a photoshoot does not automatically give you full rights to use the images however you want. The key issue is the agreement or contract with the photographer.

In general, copyright starts with the photographer unless specific usage rights are transferred to you, typically in writing. If you want to use the photos for magazines, flyers, or promotion, that should be clearly covered in the agreement. Without that, your rights may be limited to personal use, depending on local law.

Whether you must credit the photographer also depends on the agreement and local rules. Credit is not always automatic, but it may be required by contract.

A photographer can provide images with a watermark, and removing a watermark may be illegal in some places because it can be treated as copyright management information.

So the practical answer is: check the contract or any written terms you agreed to. If nothing is clear, ask the photographer directly to confirm what uses are allowed and whether credit or watermarking is required. For future shoots, get commercial usage, credit, and watermark terms agreed in writing beforehand.
