How to take pictures of the explosion?

Lead: I believe that friends who have played zoom lens for a while will feel that their room for improvement seems to be much smaller, or they have lost the motivation to try new skills. But this time, I want to introduce you to a successful photography skill? Pull the explosion!

When you use a relatively slow shutter (115 seconds to a few seconds), press the shutter and immediately turn the focus ring of the lens to achieve the explosion. Of course, the shutter value required to achieve the explosion effect in different environments is different, and more experiments are needed in this respect.

Tensile explosion effect

Because the slower shutter is used in blasting, the lens will enter more light, so it is necessary to increase the aperture value (the higher the aperture value = the smaller the aperture). Practicing explosion in a well-lit environment may overexpose photos, but the chance of overexposure in a dimly lit place will be reduced. In the busy downtown, neon lights can be seen everywhere, and practicing blasting against these brilliant lights will have a good effect. Keep your hands steady-the slow shutter makes the slight hand shake very obvious, and the smooth radiation you expect will become a mess! At this time, the tripod will become your good friend! When there is no tripod, you can put the camera on a stable plane to reduce vibration.

There are two ways to pull the explosion:

1. Forward flushing type

Pull the focus ring from the focal length 18mm to 105mm.

2. Radial effect

Pull the focus ring from the focal length 105mm to 18mm. You can see that the residual image in the middle is pulled out of the center point.

A small movement change, the same lens can achieve a variety of explosion effects.

You can compare these two original images with the above two images:

The above is an image with a focal length of105 mm.

The above is an image with a focal length of18 mm.

Here are some tips:

Reasonable use of tension and explosion function

Smooth zoom: If you want smooth radiation, you should avoid turning the focus ring quickly and slowly. You can practice how to turn the focus ring at an average speed. Don't you like radiation? Fast and slow? It can actually create another effect. You can stop before or after turning the focus ring, or even rest in the middle of turning 1 sec! At the moment you stop, the exposure time of this focal length image will be longer than other focal lengths, which will be more obvious in the photo. You can go further, the focal length is about 50mm, so that the middle image will easily become the focus of the picture!

Flash mirror: Flash mirror can also be used when drawing and blasting. The flash will freeze a part of the picture, and the dynamic picture made by pulling the focus ring will surround the frozen part. Some cameras use night vision mode, which also allows you to turn on the flash when exposed for a long time. )

No zoom lens? No problem, you can still play! Even if your camera won't let you zoom manually when the shutter is long, you can still have one? Opening the pedal zoom shutter for a long time and taking a big step forward or backward can also achieve the explosion effect. (Note: This method can easily shake the camera, resulting in blurred images. More practice can reduce this situation. )
