How to use long exposure

Lead: Usually, the shutter on the camera only opens for a fraction of a second, just to let enough light fall on the film or image sensor, so as to ensure that the hue and details of the real object can be reproduced properly. However, photography is not only a technology of making photos, but also an art of creating works by using visual effects.

How to use long exposure is one of the skills used by professional photographers to get vivid photos. By opening the camera shutter for a long time and letting more light enter the camera, photographers can take really amazing photos. If it shows running water or cars driving on the road at night, the photo looks particularly impressive.

Long exposure will record another kind of beauty that we can't capture with the naked eye. For example, taking a night view of a city and taking colorful car lights with long exposure can highlight the theme of this bustling city. What should we pay attention to in such an attractive special photography technique?

Long exposure photography has the following aspects to pay attention to:

Stability comes first.

A tripod is essential, even if there is no tripod, there should be a place where the camera can be placed stably. For example, on the beach, on the steps, on the table and so on.

Try not to touch the camera to complete the shooting process.

Use timed shooting or preferably have a cable release or remote control to further avoid touching the camera. You know, when you press the shutter, it is easy for your hand to make the camera vibrate slightly, and it will always vibrate organically if you press it lightly.

Turn on the mirror pre-lifting function.

If it is a SLR camera, the vibration of the reflector itself will also affect the stability of the fuselage. Turn on the pre-lifting function of the reflector before shooting. When the shutter is pressed for the first time, the reflector will be lifted first, and then you can officially shoot. Sometimes, you just need to close the curtain to finish shooting.

Set the sensitivity to the lowest.

The lower the sensitivity, the better the image quality. Moreover, long-term exposure is prone to noise, so it is better to minimize the sensitivity impact that is prone to noise.

Shoot with a small aperture

If there is no special requirement, a small aperture can increase the depth of field and avoid some slight effects.

Wide-angle shooting

The depth of field at the wide-angle end is very large, and you can't see the jitter caused by other inevitable factors (such as cars passing by in the wind).

After reading the main points that need attention, let's talk about how to use long exposure shooting.

Ensure the clarity of the image subject.

Some special photography techniques, such as long exposure, are great challenges for photographers. Although there are many opportunities to take good photos with a hand-held camera and a fast shutter, long exposure at night or dawn will be very charming once it is successful.
