I have many people photos that include family members, but since I am opposed to posting them on the internet, they do not get added to my stock portfolio.
In order to submit people images on the various stock sites, each photo requires a signed model release from each person in the photo. This gives the photographer and agency permission to sell and license the image for various media uses.
Going up to complete strangers and having them sign a model release is not something I can do, so therefore I do not get the people images that sell so well on the stock sites.
Until I can work up the nerve to approach people in this manner, I will continue to shoot people from behind, at a distance, or in parts so I can use them in my stock portfolio.
