Long exposure on the Canon EOS 30D works by allowing the camera's shutter to remain open for an extended period of time, typically longer than one second. This allows more light to reach the camera's sensor, resulting in a brighter and more detailed image, especially in low light conditions. To use long exposure on the Canon EOS 30D, you would need to set the camera to manual mode, select a slow shutter speed, and use a tripod to prevent camera shake during the long exposure. **
