How does the camera take a static afterimage?

For moving objects, if we don't need to freeze the subject, deliberately adding afterimages will make the photos interesting, highlight the high speed of the object and highlight the light traces left by traffic when shooting at night.

For photos like this, we only need to use M files to guess how much exposure time is needed according to the moving speed of the object. For example, in the above picture, the shutter speed is set to110 second, and the subway moving at a high speed moves110 second, which can leave a light drag afterimage.

Jiao Wai's shooting skills.

When we take pictures, we usually ask for clear pictures, right? The focus is accurate and the sharpness is enough, but in fact, Jiao Wai photography also has its own uniqueness? Do you use mottled lights when focusing, especially the night view of the city? Outside, it is even more beautiful.

Use manual focusing to complete the blur effect? Turn up the aperture as much as possible? To shoot the scenery of Jiao Wai, we just need to focus the lens manually. The larger the aperture, the better, which can make the point light source as round as possible, because it is the focus. Outside, the blur caused by hand shock can be ignored, so the shutter is slower? It doesn't matter, just pat it with your hand. Is it necessary to support it with a tripod? Ok, shoot at night, use M file for manual exposure, and set the appropriate aperture shutter value.
