I'm would like to know, for people shooting street candids of people whom they do not know (in public) and would like to submit a street photo for a contest, do they need to obtain permission from the subjects before submission for the contest?
What are the implications if, for example, in the T&Cs of the contest, upon submission you will grant them (contest organisers) rights to use your photos as they wish, and your subject chances upon the photo thereafter and demands compensation?
My consideration now is that since the photos may be used for commercial purposes, as a hobbyist, shouldn't submit the photo because ethically, prior permission has not been obtained from the subjects. It would be a rude shock if the subjects find their photo in some mass media without prior knowledge & consent.
Thanks alot in advance.
