Meaning
A strip of film with sprocket holes along both edges and a few frames in a row. It represents analog film, cinema history and film photography.
Film photographers post it with grainy, warm-toned shots, and it suits throwback albums or movie trivia: “Shot a whole roll on my old camera 🎞️ developing it this week.” It has a more vintage, artistic feel than 🎥, which points to active filming.
