“The presence of the camera, critics argue, makes people either self-conscious and inhibited or allows them an opportunity to perform, but in neither case are people acting naturally. For Rouch, though, the camera functions as a “psychological stimulant” that, while perhaps affecting behavior, allows people to do things they otherwise wouldn’t, therefore revealing character. Paradoxically, Rouch sees the camera as adding an element of artifice to a situation that ultimately results in greater truth. As he puts it, the camera is, for him, less a brake than an accelerator.”
