The law here says that the camera is an extension of the eye. You can take a photo of people if they are in a public place where they can expect to be seen. Putting photos on a web site such as this is not publication and there is no financial gain. Furthermore, I am very careful never ascribe uncharitable motives to people in my labels so there is no libel. If I were to try to sell this image, I would need releases from everyone who is recognizable. I have no intention to sell this image.
I often thought, what would happen if some stranger came up to me and said, "I would like to take your photo--just acting natural while you are having dinner. Will you sign this release saying it's ok?" I thought about how I would react--signing my name for a stranger on a piece of paper I didn't really understand. What am i releasing...all my money? Then he wants me to look natural...how can I? Get real guys! Obtaining releases would unlock a Pandora's Box, cause riots!
If we do not assert our right to take pictures in public places, photography will be reduced to studio and florals or impersonal lightening and fireworks shots. I am not hurting anyone and I am documenting my community and way of life. I see nothing unethical about it.
