I came across this some time ago… and I think through this site by Jim Johnson… Below is from “Click here to disappear: thoughts on images and democracy” by David Levi Strauss:
Photography has always had the potential to democratise images, but it has seldom worked out that way in practice. Digital imaging has made image-making devices ubiquitous. Many more people now possess the means to make images more of the time. At the same time, images are primarily used, in the public image environment, to influence public opinion and encourage the consumption of products and services. What is the relation between these two phenomena: near universal private image-making capability and widespread manipulation through public images?
