Also, a question. Do I have to have a model release of public photo's I want to enter in comtests when the prize is money or equipment? Almost all contest rules I've reviewed call for one.
A couple of things. If you live in the U.S. any image you make in public property is yours to do as you please. This is still protected under the 1st amendment..Of course this is one of the things that the administration wants to change, but until then, it is fair game.
To my knowledge, none of that is correct.
Recognizable faces and even buildings may not be used for commercial purposes without a legal release by the model or their agent or, in the case of recognized buildings, by the property owner.
As the stipulation in most contests includes the right for them to use the image for "any" purpose (that would include commercial purposes - and if you didn't know this, start reading the fine print for these contests), they insist on model releases so that they don't get a lawsuit later on if and when they use the image for something. The same is true for publications such as magazines.
As far as I know, this has been the case for a really long time, and the administration is not interested in making any changes to the current laws regarding this.
