An insider is one who has more knowledge about the place itself, having a better idea of the community and surroundings. His viewpoint may of course, be then biased; he has inside information of the place. An outsider is the exact opposite – someone who does not have much knowledge about the place and an unclear idea of the community and surroundings. His viewpoint will be based on his own interpretation of the place and may be misleading.
This can thus greatly influence what the readers will perceive about that place. The natives of the place would, most probably, put on a facade for the outsider, showing only what they desire the world to see them as, in order to mask the unknown while not revealing the truth about the place, be it their culture or traditions. However, an insider is in a better position to photograph a place, considering the fact that the insider is not biased and will be able to produce a picture that will depict a neutral stance.
An outsider does not have any idea about the place and its hidden identity. The outsider is in a worse position as compared to the insider when taking a photograph of a place. Despite the fact that the insider could be biased, he would be able to portray truthfully, a part of what the place is really like, as compared to the outsider, who would show an entirely wrong image of the place itself.
