Filming in low-light conditions can be challenging, but with the right techniques, you can achieve high-quality results. Start by using a camera with good low-light performance and adjusting the ISO to brighten the image without introducing excessive noise. A fast lens with a wide aperture (e.g., f/1.8) can let in more light, improving clarity. Stabilize your camera with a tripod to avoid motion blur from slower shutter speeds. Use available light sources creatively, such as candles, lamps, or streetlights, and consider adding portable LED lights or reflectors to enhance illumination. Finally, color grade during editing to fine-tune brightness and contrast for a polished finish.
