I had this thought cross my mind while reading the post on Street photography and the ethics of displaying the photos.
I understand if a photo is legally taken, it (in most circumstances) will not require things like a Model release. That is until you want to sell it.
So if I take a photo of someone, and for some reason that photo becomes famous (or infamous), I now want to sell it. What becomes of the requirement for model releases etc?
How do the Paps get away with taking photos and selling them off without release forms?
