Exposure zoom shooting method

Lead: Many players are used to taking the conventional or aesthetic route. Although the picture and composition have reached a considerable level, there is a little less dynamic effect in visual tension, which makes the whole picture look a bit lifeless; In order to make the works more vivid, we provide several methods to create dynamic images, which can be used as the direction for everyone to follow when creating.

Photography skills of long exposure photography first aid seal

? The focal length of "Lens" is not limited, mainly based on the existing styles, but it is suggested that the style with shockproof and manual focusing function is better, which can better meet the shooting needs of some low light sources.

? Exposure: Because the slow shutter is often used in dynamic images to achieve dynamic effects, it is best to use a tripod in addition to mastering the shutter time when shooting, so as to avoid the problem of blurred images.

? Daylighting is mainly natural light, but because the light source of some shooting scenes is complicated, it is necessary to use a reducing mirror or a gradient reducing mirror for correction to achieve the purpose of exposure balance.

? The composition direction is not limited, but it is suggested that the subject should be placed in the center of the picture as much as possible when shooting, so that it is easier to achieve the purpose of dynamic focusing.

? In addition to the tripod, the combination of various filters and focusing modes is also an indispensable auxiliary tool for shooting dynamic photography.

Long exposure method

Time exposure, in short, is to keep the shutter open continuously with a slow shutter, so as to achieve the dynamic flow effect of the subject. Generally speaking, shooting this kind of subject matter can be cut in two aspects. What's the first one? Different shutter differences for the same subject? What's the second one? What is the difference between different subjects of the same shutter? Although they look complicated, you can get a general idea of their differences by referring to the sample diagram file on the right and comparing it with the text description.

The former shooting method is also a common trick for ordinary players. Its main application principle is to use a slow shutter to keep the shutter open continuously, so that the originally seemingly ordinary water becomes a very beautiful trickle. In addition, the beautiful lines dragged by ordinary headlights are also photographed in this way. As for the latter, although the slow shutter is also used to achieve similar goals, the difference is that this shooting method is fixed within a certain shutter time, and the blurred sense of speed caused by long-term exposure of the subject background makes the image more tense. But no matter which way is adopted, you need to use a tripod to assist shooting in time, because it requires a long shutter exposure time.

A necessary tool for long exposure in photography

Because of the long exposure time, the required shutter speed must exceed the safe shutter speed for hand-held shooting, which is almost impossible to achieve. Therefore, tripod and cable release are needed to assist shooting and avoid the problem of blurred images.

In addition, although the above two shooting techniques are similar, they are quite different in different themes or time periods. For example, if you want to expose the trickle effect of water flow or waterfall for a long time during the day, many beginners will find it impossible in the shooting process, because no matter how you shoot, the image is overexposed, which is due to the fact that you didn't buy an nd filter to reduce the light, so it is impossible to expose it for a long time during the day; Wouldn't it be easier to shoot the car lights at night?

In fact, it won't be difficult to take a successful photo, but it's really not easy to take a good photo, because at night, if you want to take a long exposure, although users can easily take a dynamic picture by lengthening the shutter time, because the light source of most shooting scenes is complex, the surrounding street lamps or lamps may enhance the brightness or even overexpose with the long exposure, although sometimes it can create a good starlight effect, but the probability is not high, so it is recommended to match a gradient dimming filter when shooting.

▲ All waterfalls, fireworks, car tracks, etc. It belongs to the category of long-term contact. Generally speaking, as long as you slow down the shutter time, you can create different dynamic image effects.

The shooting of dynamic images is as follows: Long-time exposure plays the track (3)

Same theme, but different shutter differences.

Same shutter, but different subjects are different.

Through the above two test files, we can find that different shutter speeds or different focusing objects can create different dynamic image effects.

ND reduction mirror is not installed.

ND-4 reducer has been installed.

Long-term exposure during the day often leads to the phenomenon of dead white image, but as long as the light is reduced by ND filter, the above problems can be improved.

Long exposure image

If the moving speed of the subject is slow, the shutter time can be extended to 16-20 seconds, and sometimes an alternative' dynamic' image effect can be created; For example, Miramar's Ferris wheel moves quite slowly. At this time, as long as the shutter is lengthened to 15 second and the aperture is reduced to F22, an image similar to hot wheels can be taken theoretically.

Long exposure zoom

The long exposure zoom technology is actually a derivative technology of the previous long exposure technology, so photographers can produce special dynamic shooting effects by adding zoom programs during the long exposure process. Generally speaking, this shooting method is mainly divided into? Shrink (looking at the distance? Wide-angle end)? And then what? Radiation (wide-angle end? Looking at the distance)? Two presentation methods, but no matter which shooting method is adopted, remember that it is best to rotate the lens with the same frequency by hand during zooming, and there can be no pause during zooming, so as to ensure the smooth and smooth lines of the zoomed image without concave discontinuity.

As for the setting, it is similar to the general long exposure mode, as long as the aperture is reduced to F 1 1? F 16, and control the shutter at 2? 4 seconds, and then select the zoom mode according to the needs of the subject, and you can complete the dynamic image shooting. However, because the above setting data is not applicable to all shooting scenes, it is suggested that users can take a look at the shooting before shooting, adapt to whether the zoom frequency meets the requirements of the picture, and then make appropriate data adjustments, so that they can theoretically shoot an ideal dynamic zoom picture.

▲ Zooming during long exposure will produce explosive dynamic effects and provide alternative shooting fun.

▲ In the process of long exposure, if the zoom frequency or speed is different, the picture lines will be discontinuous. Generally speaking, users can get the desired image effect in theory as long as they try a few more times.

The greater the change of focal length of the small pie, the more obvious the light trace.

The greater the change of focal length, the more obvious the optical trace effect is. For example, from the wide-angle end to the telephoto end, the light trace effect will be quite obvious, and of course the feeling will be more gorgeous. However, because the image failure rate is still high, readers are advised to take more images when shooting, and then find out the satisfactory image works.
