Professional skills of super wide-angle lens depression angle and backhand

Lead: In order to make super wide-angle works have refreshing surprises, in addition to the above skills, don't forget to observe the world in the viewing window from different angles. Because according to most people's shooting habits, most people shoot from a normal head-up perspective. Unless the picture itself has special highlights, it is unlikely to cause chorus. So the next time you shoot, try to frame the picture with a rare angle.

On the visual psychological level, the bottom-up backhand is like the perspective of children and pets looking at the world, which will make the subject in the picture exude a towering, solemn, great or rising visual effect; The top-down lens is like a king's vision, as if everything is under your control. Of course, don't forget that the super wide-angle lens can leave a deep impression on people visually because of its unique perspective deformation, and if this feature can be applied to two perspectives, it will bring more visually shocking viewing effects. Let's explain the techniques of overhead and overhead shooting. As long as the players try to master and use it flexibly, I believe you can also shoot impressive ultra-wide-angle works.

▲ Shooting buildings at elevation can give viewers a tall, solemn and authoritative visual feeling.

▲ As close as possible to the target, with the sky as the background, it is most suitable to highlight the theme you want to elaborate.

▲ Even ordinary landscape photos can produce beautiful works through the interpretation of super wide angle and basic composition.

▲ Shooting portraits through ultra-wide angle and elevation angle, especially the slender figure of the model.

Shoot up

When shooting at a super wide angle, it means that the camera shoots upward at a position lower than the target (such as squatting or even lying on the ground). Due to the double factors of shooting angle and perspective deformation, the subject looks more upright, and it is usually used to shoot buildings or statues, which can produce a dignified and authoritative picture atmosphere. However, if it is used in portrait photography, it will bring different viewing experience, such as trying to shoot a petite figure with high visual effect, or emphasizing the slender legs of the subject. The closer to the subject, the more obvious the effect.

When shooting a landscape theme, whether it is a beautiful sunrise or a vast night star, players can bring the sky and scenery into the camera through a little elevation and a three-point composition, which can not only emphasize the key points of the picture, but also make the picture more stable and tense.

Due to the physical limitation of focal length, that is, shooting with a wide-angle fixed-focus lens with a large aperture, the effect on blurring the background is still limited. Therefore, when faced with a messy background (such as extreme sports, sketching, etc. ), the benefits of elevation shooting will be highlighted, because it can not only capture the tension of the protagonist (jumping in the air), but also achieve the purpose of purifying the background with the sky to highlight the subject.

Matters needing attention in elevation shooting

▲ From these two examples, it can be clearly seen that the distance and elevation angle from the subject during shooting have a great influence on the creation of screen vision.

? ▲ When shooting from the elevation angle, because a large area of bright part (sky) will affect the metering result of the camera, you can use the spot metering mode to meter the subject and shoot the works with ideal exposure.

Pay attention to elevation angle

When shooting an elevation view with a super wide angle, we must pay special attention to the shooting angle and the distance between the camera and the subject. Unless you originally wanted to emphasize an image expression in an exaggerated way, I suggest you observe the changes of the picture at different elevation angles through the observation window before pressing the shutter. Generally speaking, the closer the lens is to the subject, the greater the elevation angle, the more serious the perspective deformation will be, but the more effective the tension is, the more dull it will be, so players can try different distance combinations of elevation angles and choose the most suitable perspective according to the shooting theme and ideas.

Take a high angle/crane lens

When shooting at a super wide angle and a low angle, it means that the camera shoots down at a higher position than the target position (for example, lifting it or climbing to the commanding heights), which will make the picture have a completely different visual experience than when shooting up. For example, shooting the city scenery from a height can easily show the depth, quantity and layering of the ground scenery because of the wide field of vision that the super wide-angle lens itself can accommodate and the perspective deformation caused by uneven viewing. Therefore, when shooting related subjects, we can use the three-point composition method, so that the ground scenery accounts for about two-thirds of the picture, leaving only one-third for the sky to explain the weather, time and geographical location at that time. Following the above viewpoint, when shooting this kind of landscape theme from the perspective of depression, in addition to the three-point composition method, you can also add the TIC-tac-toe composition method, and put the famous landmarks in the city or the highlights in the picture on the golden intersection, which will make the whole picture have the center of gravity and the picture more stable.

When shooting portraits at a low angle, players can make good use of the characteristics of perspective deformation, so that women with fuller lower bodies can also have a slim visual experience; Or the closer the lens is to the face of a person or pet, the more interesting effects such as a big-headed dog can be taken.

▲ Shooting urban scenery or indoor landscaping with super wide angle and depression angle can easily show the depth and layering of the picture.

? ▲ When shooting, you may wish to make good use of the basic composition rules and try to find the center of gravity of the picture.

▲ Shooting portraits with super wide angle and depression angle will make the lower body of the character have slim visual effects.

Pay attention to measurement mode

In addition, when shooting at elevation, photometry is also the key point to pay attention to. As mentioned above, the elevation view can purify the background in the sky, but it will also affect the metering effect of the camera, especially in the case of backlight, so unless it is presented in the form of silhouette, it is suggested that the metering mode should be "center offset metering" or "spot metering" when shooting, and the effect will be ideal.

Precautions for tilt angle shooting: pay attention to your own safety.

Players should pay special attention to their own safety, including whether the road is wet or not, when looking for an ideal place to shoot scenery or urban scenery while climbing mountains. Whether the hinterland is too small. And try not to get too close to the edge of the cliff to avoid accidents.

▲ If the camera body itself has the function of flipping the screen, you can make good use of it to help you finish shooting more easily.

Looking for the core value of pictures

Because the super wide-angle lens can accommodate a relatively large number of scenes, players need to look for bright spots in the picture to set off the center of gravity. Because a beautiful super wide-angle photo should not only have beautiful elements, but also achieve the purpose of visual focus, which is a perfect work. Therefore, players are advised not to pick up the camera for special shooting when shooting any scene. Instead, we should first calm down and carefully observe the picture in front of us and think about how to frame the center of gravity of the picture, so as to shoot an ideal video work.

Generally speaking, in the face of a brand-new scene, we might as well take the three-point or tic-tac-toe composition method first, try to occupy two-thirds of the focus or important scenery in the picture, or put it at the tic-tac-toe intersection. This seemingly simple and basic composition technique can often make you shoot a focused and not monotonous work. In addition, you can also try to add different elements to the image to create your own eye-catching focus in the picture. For example, some players don't like people in the camera when shooting scenery-related themes, but if the right person is arranged in the picture, it will not only destroy the picture, but also achieve the finishing touch effect. Or you can use the stagnant water on the ground, the glass curtain wall of the building and the polished marble floor to shoot a mirror image of contrast reflection, which can also make the picture more attractive and interesting.

In addition, the slow shutter is also an available technology, especially when shooting landscape themes at night. When using ultra-wide angle with slow shutter, not only can you shoot a wide view, but also the image can present a dynamic and lively visual experience.

? ▲ It is not difficult to shoot a super wide-angle work. As long as you can catch the bright spot in the picture, you are half successful.

▲ The timely embellishment of the characters in the landscape photos will bring extra points to the works.

▲ Special effects shot with slow shutter are also one of the ways to form a bright spot on the screen.

Make good use of Live View to get a viewing rate of 100%.

Have you ever found that sometimes the photos you take are slightly different from those you see on the viewing window, and there are usually some irrelevant scenes in the corner, especially when you take pictures with super wide angle. It turns out that because of the product positioning factor, the viewing angle of most non-high-order DSLR models in the optical observation window is less than 100%, which will lead to images that were not seen at the beginning. To solve this problem, the fastest way is to use live view for framing and composition, except changing the DSLR with the viewing angle of 100% in the framing window.

When you turn on live view, the image is directly transmitted to the photosensitive element through the lens, without being reflected by the mirror and the pentaprism, so the above problems will not occur. Therefore, in the face of subjects that need accurate composition, Live View will be the best helper for your composition. It should be noted, however, that because most DSLR's real-life focusing speed is not very fast, it is not recommended to shoot the subject moving too fast. If necessary, a tripod can be used for assistance to obtain a stable image.

▲ Composition with live view.

▲ Use the optical observation window for composition.

▲ When shooting with the viewfinder, unnecessary scenes may enter the camera, which can be avoided by switching to live view.

Exchange high ISO and large aperture for stable images.

Ultra-wide-angle lenses generally have no built-in shock-proof mechanism, but sometimes you can't take pictures in order to travel lightly or when you can't use a tripod (such as museums and restaurants)? Don't worry, in fact, as long as players make good use of the focal length characteristics of the super wide-angle lens, combined with the large aperture of the lens and the high ISO available in the fuselage, they can shoot successful image works under low light source. When using ultra-wide angle, because the safety shutter is much lower than other focal length lenses, as long as the ISO value is raised in time and the maximum aperture is used as much as possible, the camera can be held smoothly and night images can be obtained without shaking.

▲ When shooting with a super wide-angle lens under a weak light source, using the maximum aperture and increasing the ISO value can effectively improve the shooting success rate.

What is a safety shutter?

The so-called safety shutter refers to the shutter speed at which the camera will not shake and the image will not blur when the shutter is pressed by the hand-held camera. Generally speaking, normal safety shutter = 1/ actual focal length. For example, when taking pictures with APS-C body and 16mm lens, the equivalent focal length is about 25mm, so the safety shutter is about1/more than 25s.
