question....

I took some pictures for a local night club for free. They are going to give me credit for the, so I thought it would be a good idea. Is there any type of a contract I should have them sign before I give them my pictures?

Hi,

Personally I would suggest getting them to sign some sort of Usage Agreement outlining the terms underwhich the images may be used. You should be able to find some through searching through these forums or Google. Although if you do need to to be totally legally sound, you should see a lawyer.

Regards,

Why would I need to do this? What would I need to include?

"pictures for a local night club" = Which might be seen as a "work for hire" which means that they own all rights if you were paid to do that. Not sure how it works if you do it for free at thier request.
"pictures at a local night club" would mean that they only get the rights that you convey to them.

I would just expand this what Jeff said even a bit further. Sorry this "I work for credit" stuff just goes on my nerves.
Does anyone really think, they will get great paid job after he (or she) will get "good" reputation and experiences doing stuff for free? Believe me, you won't get reputation of good photographer but only of cheap photographer.
You will definitely have huge pool of clients, which unfortunately will turn back next second when you will start charging (or charging more). Why? Because you showed them there's chance to get free service. And if you are not in market for free services anymore, someone else will be, so they will go find that someone else. They won't stay with you.
Next thing to consider is this what we (at least I think I can say this for Jeff and me) are thinking now "look and idiot doing stuff for free". Why do you think there won't be another new kid in the game who will also do stuff for free once you decide it's time to start charging? If you think there won't be, then think again. Maybe that guy from last year decided to start charging, and then you showed up. And things go on exactly this way, and result of this is that we have now already... damm low prices for our services.
But on the end it's up to you. If you feel like doing charity work then feel free.

Yes I know all of this and it was a trade in services. (he did me a favor and now I am doing him a favor)
