Legal Question in Technology Law in California

Re: Can I use video that I shot at a tennis facility on my website?

I don't think so. This isn't really computer and technology law, but touches more on the areas of privacy tort and intellectual property.

I think the issue is whether the pictures are newsworthy, or whether you are commercially exploiting the likeness of the players. Sure sounds like the latter.

Also, check the terms of your admission to the event. It may contain prohibitory language.

I think you need a license or other agreement with the pros and maybe the club also.
