The camera is an important symbolism in the film. The scene that this stands out is the when Chris tries to photograph Logan, the only other black person at the party. When the flash goes off in Logan's face his demeanor changes. Physical symptoms manifest which include a nose bleed, fear in his eyes and lunging at Chris saying "Get out". Initially, this perception of this is interpreted as aggression, but later he learns that Logan was actually warning him.
Lenika Cruz puts the camera symbolism in context in the article "In Get Out, the Eyes Have It",
"It was hard not to watch that scene without thinking of how important camera phones and video recordings have been for many African Americans experiencing police violence—especially in light of an earlier scene in which Chris is the apparent target of racial profiling by an officer. Cameras, Get Out suggests somewhat plainly, have the power to reveal. It’s no coincidence that photographic evidence later provides Chris with his biggest clues as he tries to uncover the Armitage family’s secrets."
