Is it a historical photograph or a photograph published in a book that someone scanned and posted on line, is it a photograph of something like a sculpture? Is your paper focused on the work of the photographer, the makeup artist who prepared the model, the digital image enhancer who altered the image, the model? There is no single correct way to cite a photograph, because there are many different reasons to cite a photograph. Your instructor would be able to give you more specific advice. In general, though, the 8th edition of the MLA guide would say something like this:
Contemporary folklore and stereotypes that we are exposed to contribute to a lack of knowledge concerning native American fishing practices. Brumbach (1986:36) noted that "popular folklore emphasizes fertilizer value of the fish but seems vague about their consumption as food." Perhaps the stereotype of the "hunter/gatherer" among anthropologists similarly attenuated a focus on fishing, as the word "fishing" is not included in the phrase "hunting/gathering." Despite this fact, in some societies, the role of fishing may have been equal to or surpassed that of hunting and/or gathering.
