Many states require sections of the liability waiver to be written in conspicuous font so that it grabs the reader's attention. A signed Photo Release form (also called a Model Release) essentially releases the model's ownership of the images captured to you or your company. With this permission, you can use the photos as you desire, whether it be for a creative art project or for a commercial advertising campaign. It is always a good idea to obtain a Model Release. In fact, some of your clients may require that you have photography releases to use your images in their projects especially if the photos include minors. If you’re in a public space, the general legal and accepted rule is that you may take photos in that area. For private venues or events, you may take photographs provided that you have the permission of the venue or from personnel who organized or managed the event. Sidewalks, streets, and public parks are considered public venues. If you’re on private property, you should get the permission of the property owner if you’re going to physically be on the property. Otherwise, that can be seen as trespass. Private property owners, security officers, and other officials can use “reasonable force” if you’re thought to be trespassing.
