Slow door of SLR camera. Why is the picture of water so beautiful that it is difficult for photographers to master it? Shooting the running water with the slow door creates a quiet poetry of running water, which adds a sense of fantasy and aesthetics.

▲ Use the slow door to shoot the flowing water, creating a quiet poetry of falling leaves and flowing water, adding a bit of fantasy and aestheticism.

So, put the characters in this slow-door "fairyland"? Undoubtedly, it can add a lot of color to the picture. But at the same time, people are not suitable for using slow doors. If the shutter speed is less than a few tenths of a second, it may burn out. So, how to keep the subject clear while ensuring the dynamic picture? In fact, it is also possible to pay attention to methods.

▲ Long exposure will make the running water "atomized".

There are two possible ways:

The exposure time of a single-lens camera should be adjusted faster, such as a fraction of a second or a tenth of a second, to keep the character in a stable posture. In this way, people can be photographed clearly, and the water flow can also be "brushed" or slightly "atomized". However, this shooting method is limited, which requires that the water flow is fast enough (otherwise, the traction and atomization effect of the water is not obvious), and the characters are also required to stay in a sitting position, without any swaying, and their hair cannot be blown by the wind.

▲F/2.82 iso:300 ambient light is relatively sufficient, and windless weather is one of the necessary factors for the success of this photo.

The post-superposition method is more reliable, that is, put the camera on a tripod and release it with a cable to shoot the environment with slow water. Then let people walk into the picture and pose, adjust the shutter to normal speed to take a portrait photo with the same composition and basically the same exposure, and finally carry out post-superposition. Of course, the shooting environment and people can be reversed.

▲ Environmental map and portrait map

▲ Shoot running water and characters separately, and then synthesize them later.

In the post-synthesis, it is best to zoom in and check whether there is any dislocation between the characters and the environment. Because sometimes even if there is no offset on the plane, the swaying of branches and leaves in the environment may lead to the ghosting of two pictures because they are not completely aligned during the masking process.

You can refer to the "superposition" often mentioned in previous landscape photography. Are you clear? Teach you to play stack photography

Finally, I would like to remind you that during shooting, please play back and check whether the composition, exposure and color temperature of the two photos are consistent. This directly determines your later perfection. I warn you again, it is very important to take such photos in the early stage. Please be careful with every step.
