Politician photos

I don't usually post twice in the same forum on the same day ...

At a parade this weekend, I photographed a state senator who was walking in the parade. Uploaded them to flickr last night. They came out nice, considering I was juggling my camera and my toddler.

Today, a new flickr user is asking if they can have copies of the shots. I Google his name, and he's an intern on the senator's campaign.

I've replied asking for the intended usage of the photos, but I'm not quite sure where I should go from there.

Public figure at a public parade, obviously, I own the photo and there is nothing stopping them from downloading the shots for personal use (and they are watermarked) - but if they want them for a website or some similar usage, where do I go?

Wait for the answer & check these sites:

And since it's for a politician & they're notorious for not wanting to pay, include this in the contract: "x. Grant of Rights. Upon receipt of full payment, Photographer grants to the Client the following rights in the Work."

Turned out to be nothing - the guy was an intern on the campaign, and happened to be in two of the shots - wanted them for his personal use. I posted them to my page on Facebook and he's using them as his profile shot.

The politician in question wasn't actually well represented in the shots, so I didn't mind letting him have them for personal use (with my watermark, hosted on my FB page)
