Photographs are a unique communication tool since it is identical to our sense of seeing. It is presumed that photographs represent reality. Just as is it not inherent in the nature of people to verify what their eyes see because they don’t suppose their eyes would deceive them – the same goes for photographs.

This makes photography a powerful and indispensable tool in the hands of those who wish to manipulate/exploit it’s aesthetics and harness it to disseminate social or political messages.
