Bulb Mode is a feature found on the majority of DSLR and mirrorless cameras. It’s actually a very helpful feature that opens up a world of artistic opportunities for your camera. Bulb mode merely permits the photographer to press the shutter throughout the duration of the shot. By selecting a manual mode or shutter priority and then beginning to scroll your selector wheel all the way to the end of the shutter speeds, you can use bulb mode

You are now in bulb mode. This implies that the camera will continue to take photos until you remove your finger from the shutter button. Some cameras will display “bulb” or just the letter “B” after 25′′ (25 seconds) or 30′′. However, using Bulb Mode does require some expertise, and it helps to know how it came to have such an odd name. To understand what bulb mode is on the camera and how to use it, we have prepared this guide for you.
What Bulb Mode Is, How to Use It, and Where to Find It
Bulb mode may be accessible on some cameras by selecting a different mode on the mode dial. If your camera has a specific bulb mode, it will typically be indicated by the letter “B.” Cameras without this feature often have a bulb shutter speed that is one increment slower than their slowest timed shutter speed. Access to this is through manual (M) mode. To get BULB and/or B to display, just switch your camera to Manual mode and set the Shutter Speed to the slowest value.
Remember that not all cameras offer bulb mode, so if you’re having trouble locating the bulb mode on your camera, think about reading your handbook or looking up more information online. The only other thing you’ll absolutely need to use bulb mode is a reliable tripod outside from the mode itself. Since long exposures are so susceptible to camera shake, even the smallest movements will result in fuzzy images.
Use of Bulb Mode
It’s time to play around with Bulb Mode, experiment, and have some real fun. Although everyone may utilize it differently, here are a few suggestions to get you started.
Realistically, digital cameras are difficult to understand and operate. The Menu systems are filled with several options, making it difficult to get a perfect uniform setting. However, one must understand them to capture good photos.
We know that understanding the various types of cameras, settings, and techniques can be overwhelming if you are new to the photography industry. Thus, we have provided this master article – camera 101, to help all beginners and even experienced photographers understand their cameras.

- The next time a storm approaches, switch to Bulb Mode to record lightning strikes. The more lightning strikes you might be able to photograph, the longer the shutter is left open.
- Position your tripod near a road, and capture nighttime light trails as vehicles pass by.
- Try fire spinning with a friend for a different take on light trails. Keep in mind that safety must always come first in these circumstances, so take care to protect the environment, your surroundings, and your gear from harm.
- Try light painting and experiment with utilizing various types of light on recognizably known subjects that you may already have lying around.
- You may achieve excellent results using a variety of lights, including flashlights, sparklers, and spinning glow sticks. You don’t even need pyrotechnics.
How To Use Bulb Mode
The three steps you must take to photograph in Bulb mode or with the camera’s shutter open are as follows:
• Use a Tripod: Mount the camera on a tripod to prevent camera movement from compromising the shot. As long as the camera is on a sturdy base, such as a wall, you can avoid using a tripod. Disable any anti-shake features that may be present on your camera or lens.
• Use a Remote Shutter Release: When you press the shutter button, a remote shutter release stops vibrations from distorting the picture. No matter how cautious you are, pressing the shutter button will always generate a very slight vibration. Fast shutter speeds make it irrelevant, however, in Bulb mode, even the smallest tremors will be captured. Use the built-in self-timer delay on the camera if you don’t have a remote cable; it works just as well. The recommended wait is two seconds.
• Change to Manual Mode: When utilizing the Bulb exposure setting, metering is absolutely meaningless; thus, change the camera’s mode to Manual. Then, pick a suitable aperture, such as f/8 or f/11, as these offer the highest image quality. In order to reduce sensor noise, also adjust the ISO to 100 or 200. Finally, practice by shooting a number of practice pictures before taking the final long exposure bulb mode picture.
Understanding Bulb Shutter Speeds
If this is your first time using bulb mode, you might be perplexed as to why the “B” option seems to take such brief exposures. Say, for instance, that you simply push the shutter release as you would normally while the bulb mode is on. In that instance, you will only be able to catch a brief exposure. This is due to the fact that using bulb mode necessitates continuously depressing the shutter release button on the camera.
Your exposure will be determined by how long you keep the shutter button depressed. However, if you just press and release the shutter button, as usual, you might only receive a 1/2 second exposure. Generally speaking, if your shutter speed is less than 30 seconds (or whatever your camera’s longest native shutter speed maybe), there is no necessity to use bulb mode.
The one exception is if you want to be extremely accurate with your shutter speed when taking nighttime photos of stars to prevent star trails. Even so, it’s typically unnecessary. The camera almost always shakes and blurs when the shutter button is depressed in bulb mode, which is a significant issue. This is simply due to the fact that your hands will undoubtedly shake; even with the most stable tripod available, using bulb mode in this manner would probably result in fuzzy pictures.

Taking Photos in Bulb Mode
Now that you’ve discovered bulb mode on your camera, it’s time to get acquainted with it. Bulb mode is a fantastic learning tool, even though it does require some knowledge of camera settings.
Activating Bulb Mode: Setting up
It’s crucial to use a sturdy tripod to keep your camera stable. Since you frequently work with extremely long exposures, even the vibration caused by your finger hitting the shutter button might have an impact on the final image. Therefore, the more sturdy your tripod is, the greater the quality of your pictures. Now is an excellent time to employ a cable release or other remote shutter trigger if you have one for your camera.
Although it’s not necessary, a wider aperture or higher ISO may be necessary depending on your topic, especially if you wish to photograph stars, record star trails, or catch other astrophotography phenomena.
Unexpected Subjects at Night
When you are taking long exposure pictures of subjects that have unpredictable occurrences or varied durations, bulb mode is really helpful. For instance, it might be difficult to forecast the duration of fireworks, and you generally don’t want to include too many of them in one photograph. Adjust your aperture and ISO using a 10-second exposure if the typical duration of a firework is 10 seconds, and then switch to bulb mode.
To start your fireworks exposure, press and hold the shutter button. Release the shutter button after the fireworks you are photographing have finished. By doing this, you can capture a long exposure photo that only captures the fireworks you desire. Since it is difficult to predict when a lightning strike will occur during a thunderstorm, bulb mode can also be helpful for recording lightning strikes. The option allows a photographer to expose a picture up until a lightning strike appears in the frame.
If you are close to getting a well-exposed photograph, it doesn’t matter if you have to keep your shutter open a little longer in bulb mode to capture a whole light trail. The beauty of bulb mode is that you get to decide exactly how long your exposure is.
Pro Tip: Post-processing can be used to darken an image far more easily than it can be used to correct a light trail that ends too soon.

Light Painting
Light painting and the other several long-exposure photography styles discussed above have a lot in common. This is the technique of illuminating a dark scene by the use of a flashlight or another light source. As the name implies, it enables photographers to capture pictures that are essentially light paints. Without bulb mode, photographers have just about 30 seconds to complete all of their “painting,” which makes it nearly hard to create sophisticated light paintings in a single exposure.
But bulb mode opens up the universe outside of the 30-second shutter speed and enables light painters to create drawings for extended periods of time. A piece of gear advice: When you initially activate bulb mode, it could seem as though you must firmly hold down the shutter for the duration of the exposure you want. Without a helper, this would make tasks like light painting practically impossible. A remote shutter release, built-in bulb timer, or intervalometer can be useful in this situation.
Note: The majority of remote shutter releases contain a “lock” that enables you to trigger the shutter and then keep it activated until you manually deactivate it. They plug into a port on your camera.
Capturing Star Trails in Astrophotography
Bulb mode is commonly employed in various astrophotography techniques. Star trail photos are created in one application using exposure times ranging from 10 minutes to hours. The earth’s rotation gives stars the appearance of streaks in the sky over extended periods of time, giving landscapes a distinctive twist. Bulb mode is a fantastic option for star trail photography since it enables lengthy exposure times.
Although extremely long exposures (i.e., 10 minutes or longer) can result in stunning star trail photographs, most photographers combine multiple long-exposure shots to produce their finished product. This is so that thermal noise and hot pixels aren’t produced by extended exposures, which heat the camera sensor. Photographers typically aim to avoid both artifacts as much as possible because they are both uncomfortable and difficult to remove.

For instance, photographers may utilize bulb mode to create 30 successive minute-long exposures rather than a single 30-minute exposure. This increases the photographer’s confidence (and reduces the risk) of accurately exposing the scene.
Use of Neutral Density (ND) Filters
Bulb mode normally requires an ND filter, a tool that prevents light from reaching the sensor from being used during the day. Filters are employed to block extra light and permit long exposures at all times of the day because daylight is typically too bright for the kind of long-exposure photography that bulb mode enables. Photographers can accomplish exposure durations of a few minutes or longer in the middle of the day with a dark enough ND filter.
This produces a silky-smooth look, making it frequently employed for photographing moving water. This method can also be used to remove crowds of people since they won’t appear in the final image if they move slowly over a few minutes. When taking really long exposures during the day, a lot of abstract possibilities become available.
