This is not the only business model used by photographers but it is a standard one. If her package includes fifteen photos that is what you get. Why would they give you the rest? Also watermarking and low res is done because many people don’t think there is anything wrong with taking photographers photos without paying for them. For some reason people don’t see this as stealing.

I only use manual focus because you’re not a real photographer if you use auto focus.

Just kidding.

I need to use it sometime when shooting macro.

RF 28-70.

Just like everyone else said. I wouldn’t use it again.
