It worked by sending a blast of air from the bulb. It looked somewhat similar to the little pump on a blood pressure cuff. On the old school cameras, there was a pneumatic valve bulb that was used as a cable release for the camera. I could have done the same thing with a long timer for the shutter (20 second shutter speed), but I wanted the flexibility to end the exposure right when the cars all passed me, and the overall brightness of the photo won't change much by adding or removing one or two seconds when we're already shooting for 20 seconds overall. The lights from the cars created cool streaks of light in the foreground. I let go of the bulb shutter as soon as the cars past. I used bulb mode to hold open the shutter as soon as I saw a few cars coming by. I took this photo in Chicago while I was there speaking at a conference. It is simply a wired remote control that allows the photographer to lock the shutter button to take LONG exposures without actually standing there and holding the button down. You can pick up a cable release for about $10 for most DSLRs on Amazon. Bulb mode is usually used in conjunction with a cable release. No one in their right mind would stand next to the camera with their finger pressing down the shutter button for an ultra long exposure. The main advantage is that it allows the photographer to achieve shutter speeds longer than the 30 seconds (displayed 30″ on the camera) that is allowed on most DSLRs. This means the camera will keep taking a picture until your finger comes off the shutter button.īulb mode is mostly used for long exposures at night. After 25″ (25 seconds), 30″, it will show “bulb” or simply the letter “b” on some cameras.

You can use bulb mode by choosing manual mode or shutter priority, then start scrolling your selector wheel all the way to the end of the shutter speeds. Today's post is the result of a question from Eric Thant, who asked “How do I shoot the bulb mode?” What Is Bulb Mode on a Camera?īulb mode simply allows the photographer to take a picture for as long as the shutter is depressed (that means pushed down, not sad…).
