Key is who owns the photos. You or your subject. Typically, if they paid for it, you'll need some permission.
Nope! Not even close.
In the US, if you pressed the shutter release, you own the photo (copyright) unless by a signed document you transfer your copyright to whoever paid you to make the image(s).
Three things determine if you need a model release to use a photo:
- How the photo will be used?
- Is the subject(s) clearly recognizable?
- How did you take the picture?
Using a clients image in a portfolio, or for any other kind of self promotion is not considered a commercial use, so you don't need a signed model release. Unless, the photo was made in a private setting, under controlled circumstances, or if the the people in the photo can be perceived as advocates or sponsors of your business.
Schwettylens,
If you are going to start charging for your photography, you really should start educating yourself about copyright law (
www.copyright.gov), contract law, publishing law, and model release law as they pertain to the jurisdiction where you will be doing business.
The best way to do that is to establish a relationship with an attorney and an accountant, both familiar with the legal needs of photographers.
