What is the significance of the bulb mode in photography and how can it be effectively used to capture long exposure shots?

The bulb mode in Photography allows the camera shutter to stay open for as long as the shutter button is pressed. This is significant for capturing long exposure shots in low light conditions or to create motion blur effects. To effectively use bulb mode, a tripod is recommended to prevent camera shake, and a remote shutter release can be used to control the exposure time precisely. Experimenting with different exposure times can help achieve desired results in long exposure photography.
