The author didn't question the artistic aspect. He says: > It’s a purely stylistic choice, employed for that one moment to cast doubt on Billy’s trustworthiness in the audience’s mind. It’s an extremely stagey choice that fits neatly within the larger series’ heightened, melodramatic style. Scream wouldn’t really be Scream without it. It doesn't mean that he's ignorant of the aspect that a camera looks differently than our eyes do, as you wrote above. The scene is not bright because of this fact. It's bright for artistic reasons, and you could describe it as overcompensation, since it wouldn't even have to be that bright to deliver a facial expression.
