What does backlit mean?
"Backlit" describes something that is illuminated from behind, so that the light source lies between the viewer and the subject. This produces one of two striking effects: the subject appears as a dark silhouette against a bright background, or it seems to glow from within. The term functions both as an adjective — a "backlit photograph", a "backlit keyboard", a "backlit billboard" — and as the past tense and past participle of the verb "to backlight", which means to arrange such lighting deliberately. It belongs especially to photography, film, stagecraft, and product design, where backlighting is used for drama, mood, and legibility in low light. A sunset portrait with the subject's hair rimmed in light, a stained-glass window glowing at dusk, or a translucent screen are all everyday encounters with the effect the word names. Precise and evocative, "backlit" lets writers describe not just that something is lit, but exactly how — a distinction photographers consider essential.
Lit from behind or from within, producing a silhouette or a glowing effect.

Etymology of backlit
"Backlit" derives straightforwardly from "backlight", a compound of "back" (Old English, indicating position at the rear) and "light" (Old English "leoht", from Proto-Germanic). As a compound verb and adjective, it developed alongside modern photography and electric lighting, becoming common in twentieth-century technical and artistic usage. It shares its formation pattern with other lighting compounds such as "highlight" and "spotlight".
