bWhat does shutter mean?
b shutter refers to an exposure method of the camera shutter. It is usually displayed in the form of 1/B in the exposure time setting of the camera shutter. The b shutter is called "long exposure", that is, the camera exposure time can be longer than 60 seconds. Compared with the fast shutter, it can capture more details of the scene. The b shutter is usually used for scenes that require long exposures such as night scenes, star trails, water flows, etc. It can also be used for special effects photography.
When shooting long exposures, it is necessary to use fixed equipment such as a tripod to ensure the stability of the camera during the exposure process and avoid blurry photos. In addition, strong light may also affect the effect of the photo, so when using the b shutter, you must pay attention to the lighting conditions of the photography environment and choose an appropriate ND filter to adjust the light and ensure the quality of the photo.
The b shutter can take some stunning and special photos, such as long-exposure photos of city night scenes, streamer photos of rushing water, etc. It can also be used for creative photography. When shooting with b shutter, you need to make reasonable adjustments to the exposure time, ISO, aperture and other parameters to get a satisfactory shooting effect. b Shutter requires the foundation of camera technology, which requires continuous practice, summing up experience, and giving full play to the potential of the camera.
