Bulb Mode Bulb mode is a camera setting that allows photographers to manually control the length of the camera's exposure beyond the usual shutter speed limitations. When the camera is set to bulb mode, the shutter remains open for as long as the shutter button is held down or until a specified time limit is reached, allowing photographers to capture long exposures of several seconds, minutes, or even hours.
Bulb mode is commonly used in low-light photography, night photography, astrophotography, and long-exposure techniques such as light painting and capturing motion trails. It enables photographers to creatively capture scenes with extended exposure times, revealing details and capturing light that would be otherwise invisible in shorter exposures. |
