First, check the lights – any flicker could mean a short. Have a backup battery pack on standby. Wear a helmet and gloves; those walls are old. Mark the boundary with tape so no one walks into a loose panel. For the raw vibe, choose a wide lens, shoot from a low angle so the graffiti feels like a skyline. Use a steady‑cam or a gimbal to keep the motion smooth while the environment feels unstable. Light the space with a single yellow LED strip to give that harsh, cinematic look, and add a small portable diffuser to soften any harsh shadows on faces. Keep the camera close enough that the dust is visible, but not so close that you trip over a broken tile. Finally, run a quick safety check each time you change gear – safety first, then art.
