How to use small aperture correctly in street shooting

Clearly explain the background environment. Many photographers like to capture what they see with a large aperture, even the topic of street shooting. Because they think it can highlight the theme they want to emphasize and add points to their works through beautiful scattered scenes, but in this way, in addition to the image can not make the viewer effectively and clearly distinguish the shooting location, it often separates the theme from the background, thus losing the meaning of street shooting. Because street shooting, to some extent, is also a category of documentary photography, its essence is to faithfully record everything you see with a camera, including the interaction between the theme and others, things and objects, and even the relationship with the environment, so it is better not to shoot with a large aperture. However, when using a small aperture for street shooting, we should pay special attention to whether the shutter will be lower than the safe value. Because narrowing the aperture means that the camera must slow down the shutter speed to maintain the normal exposure of the image. If the shutter speed is too slow, it will increase the chance that the photo will be blurred due to hand shock. Therefore, before shooting, players can observe the weather and light distribution at the scene to decide which shooting mode to use. ▲ Sony NEX-7+E18-200mm F3.5-6.3 OSS 39mm end.

For example, on a cloudy street, because the sun is blocked by clouds, it will produce soft diffuse light, which will not drastically change the environment. At this time, you can rest assured to adopt the M full manual mode. First, fix the aperture between F8-F 1 1 as appropriate, and set the shutter according to the focal length of the lens and the stability of the photographer's hand, based on the principle that it is not easy to shake before shooting. If it is too dark or too bright, adjust the ISO. ▲ When it is cloudy, you can safely use M mode. Usually the same set of parameters can be used to deal with the problem of street shooting.

However, if street shooting is performed on sunny days, players are advised to shoot in AV mode instead. Because there will be a great difference in contrast with or without occlusion in the scorching sun, if you use M mode to deal with the ever-changing street shooting problem, unless you have a full grasp of the aperture shutter and ISO combination in each environment, the probability of failure will greatly increase, so you might as well use AV mode to fix the aperture, and then leave the rest to the camera to decide. Players only need to concentrate on capturing the subject of street shooting. ▲ It is recommended to use AV mode, with exposure compensation, to keep shooting fluency in sunny and sheltered environment.

The application of high ISO and street shooting is usually in the case of narrowing the aperture and keeping a certain shutter speed. Only by improving the ISO sensitivity can the image maintain the correct exposure. However, some old ISO values are generally not too high. At this time, you might as well set the camera style to "black and white" and then shoot with high ISO! After that, by adding some contrast in post-production, the work can be similar to the style shot by Japanese street photographer Daido Moriyama. Is it unique? Improving the success rate of quasi-focus Another purpose of reducing the aperture in street shooting is to improve the success rate of quasi-focus through longer depth of field. Because apart from the topic of street shooting like a model, ordinary street shooting uses observation to capture the excitement of a moment, and photographers don't have much time to think slowly, compose and focus. It can be seen that "speed" is the key to street shooting! Therefore, in the street shooting subject full of changes and uncertainties at any time, instead of worrying about the uncertainty of defocusing with a large aperture, it is better to narrow the aperture to improve the success rate of focusing. ▲ The decisive picture in street shooting often appears at that moment, so you don't have to worry about the subject's out of focus when shooting with a small aperture.

In addition, in order to gain time or reduce the possibility of being discovered by the subject, some players will hang their cameras directly on their chests or waist-high for blind shot. At this time, if they shoot with a large aperture, there is a great chance that the protagonist will be blurred and the background will be clear because they can't focus on the theme correctly, so the image will become meaningless. Therefore, for the players who want to shoot with blind shot, the benefits of narrowing the aperture appear here. A longer depth of field can not only avoid the subject taking off. ▲ Even if the camera is placed on the chest or waist blind shot, it is not easy for the protagonist to lose focus and blur because of the long depth of field of the small aperture. Make good use of wide-angle fixed-focus lens to improve the success rate of street shooting. In addition to reducing the aperture mentioned above, players can also use a wide-angle fixed-focus lens to shoot (for example, equivalent to 28mm or 35mm), because the inherent optical and physical characteristics of wide-angle can easily obtain a longer depth of field, and even if the camera is placed at the waist, the success rate of blind shot will be higher than that of using a medium-telephoto lens. Another reason is that besides wide angle, it is easy to record the subject and the environment together, and the fixed angle of the fixed-focus lens can also allow the photographer to practice the ability to preview the picture he wants to shoot, which will be of great help to the cultivation of photographic eyes. Shows the prosperity of this city. In the application of street shooting, in addition to the above characteristics, players may also use its additional characteristics to create pictures, which make the pictures present completely different styles and tonality, among which the use of slow shutter is the most representative. Just like the principle of shooting car tracks in landscape photography, when the aperture is reduced and photos are taken with low sensitivity, the only way to make the exposure of the image normal is to slow down the shutter speed to increase the amount of light, and the bustling pedestrians and vehicles in the city are the best targets for slow shutter. ▲ Let dynamic and static elements exist in the picture at the same time, and show the busy feeling of the city through comparison. To add such an element to the topic of street shooting, we should first pay attention to the movement of pedestrians or vehicles on the streets of our city, and then decide whether to shoot in the first person or the third person. The biggest difference between these two angles is that the former is that the player himself is shooting from a flat angle when standing on a busy street or road, or shooting from the waist or even the ground, and the photos obtained will make the viewer feel immersive; In the latter case, the camera is pointed at the street or across the street, shooting perpendicular to the direction of movement, just like a bystander watching the visual effect of the story. ▲ Focus chasing is another creative extension of street shooting, which uses the shutter speed with reduced aperture to chase the moving subject, and then produces a sense of speed of the picture. Of course, in order to make the work more attractive to viewers, we can also try to arrange dynamic and static elements in the picture. Looking for traffic lights on street corners, station platforms, MRT entrances and exits through keen observation, there will be pedestrians or vehicles moving and stopping at the same time, and then capturing the dynamic and static movements with a slow shutter can not only successfully create a sense of busyness in the city, but also make the images have strong contrast and focus. ▲ Exposing yourself in the street from the perspective of the first person will give viewers the illusion of being there.
