Taking photographs with long exposures is a technique used to track lights, visualize starlight, and create light-painting images.
Normally, DSLR cameras automatically allow only 30 seconds of exposure, more than enough time to produce these effects.However, to make it easier for users who want to customize the picture, Bulb mode maintains exposure while the shutter button is pressed to capture long periods.
Here’s how to soften the camera flash with alternate diffuser
In order for the bulb mode to work, tripod is necessary, since in long exposure the photo will record the minimum movements of the hand.In addition, the use of a self-timer is indicated so that it is not necessary to keep the button pressed during the exposure period.
In this example, we will use a Nikon D3200 camera and for demonstrative reason we will not use a self-timer.Check it.
