Asking for Advice on Licensing Street, Culture, and Daily Life Photos from Africa

Hi everyone,

I am currently photographing street scenes, culture, and daily life in Africa and would like to sell these images as stock photos. However, many of these photos feature large crowds of people, and obtaining written consent from each individual in these groups is nearly impossible.

The images are documentary-style, capturing general aspects of everyday life, rather than focusing on specific individuals. Given these circumstances, what are the essential conditions I need to follow when submitting these types of photos without explicit consent from the people in them?

Any advice or guidance would be greatly appreciated!

Thank you in advance.
