How to make a good portrait of “city night scene”? Don’t ignore these six key points!

The city night scene portrait is a photographic subject that many photographers like to shoot. The colorful city night scene adds different beauty to the portrait. At the same time, the light source is more difficult to master because of its complexity. < / P > < p > in fact, as long as you pay attention to some key points, you can take some “different artistic beauty” night portrait. Here are six key points about “shooting a good night scene portrait of the city”. I hope it can enlighten and help you. < / P > < p > safety shutter: according to the situation, some people can take a clear picture of a person in 1 / 10 seconds, and some people can blur the image in 1 / 100 seconds. It’s very important to keep the camera steady at night. If you keep your hand steady, you can reduce the noise caused by high sensitivity. < / P > < p > appropriate ISO: if you don’t practice the “iron triangle” and have no confidence in taking photos by hand, you have to improve ISO. In fact, for high ISO, we don’t have to worry too much about it. It’s more common for people to have noise at night. It’s better to have noise than to take blurred pictures, and the two disadvantages are lighter. So you can try high ISO to shoot. < / P > < p > large aperture lens: when shooting people at night, the light is dark. At this time, you can get twice the result with half the effort by choosing a lens with large aperture, such as 50mm f1.2 or 1.4, so that you can press the shutter as willfully as in the daytime. < / P > < p > of course, you don’t have to use a large aperture to take a portrait. Whether you should use a large aperture depends on the scene. For example, when your shooting background is very clean and does not interfere with the main body of the portrait, or when the environmental factors are integrated with the portrait and cannot be “subtracted”, the parameters of small and medium aperture can be used for shooting. < / P > < p > at night, the light is not good. I believe many people have encountered the problem of focusing because the light is too dark, that is, the lens zooms back and forth and fails to focus. It’s not only easy to miss the shooting opportunity, but also to a great extent dissipate the creative mood in the shooting. < / P > < p > it can be achieved by focusing on the bright spot, auxiliary lighting, focusing edge, focusing first, then composition, manual focusing + real-time viewing, etc. As can be seen in the previous article < / P > < p > the artificial light source of night scene is the closest to the point light source shape, and the shooting scene based on artificial light source is very suitable for shooting scattered scenes. Compared with natural light source, the biggest advantage of artificial light source is controllable. You can adjust the effect of the scatter by changing the number and color of the lights. < p > < p > as far as the SLR lens is concerned, it is usually said that the larger the aperture of the lens, the more obvious the scatter. That is to say, the larger the aperture, the smaller the depth of field and the more defocusing range, the stronger the defocusing effect. On the contrary, the smaller the aperture, the greater the depth of field and the smaller the defocusing range, the weaker the defocusing effect. < / P > < p > if your aperture is not too large, let the main body close to the lens and control the distance between the background and the main body. The larger the distance, the more obvious the scattered scene. As shown in the figure below, the aperture is not very large, only f / 5.6, but because the main body is very close and the background is very far away, the scattered scene is still very obvious. < / P > < p > night portrait shooting, because the light is dim, so when shooting, you must use the external light, you can use all the things that will light up, fireworks sticks, small star lights, city lights can be used. The use of foreground is an effective solution, and because of the relatively “messy” environment, it is also one of the effective methods to simplify the picture. At night, the light string and light can be used as the foreground to shoot out the spot effect and form the layered sense of the picture. Is it necessary to take a face in a portrait? Of course not. Everyone has the most beautiful part, the so-called “details see the real chapter”, we should be good at finding the shining point on the model. In addition, in a group of portrait photos, local close-up photos can also supplement the story and picture, such as super close-up of lights in the eyes and fireworks in the hands. < / P > < p > on a rainy night, the city streets are full of strange lights, like oil paintings. It’s a good time to take pictures. It’s more atmosphere than usual. At this time, even the ordinary street scenes are very interesting. < / P > < p > if you are good at observing, you will find the change of color in rainy days, which is very expressive for photography, especially the change of cold and warm. In rainy days, it’s more suitable to take pictures with stories. An umbrella and a pool of water can make a story like and movie like picture. < / P > < p > in addition, the dripping rain, the wet ground after the rain stops, and all kinds of static water are special viewfinder elements, which can capture quite unique picture effects. < / P > < p > the conventional “fixed format” shooting is a little ordinary. You might as well use the slow door to play with creative ideas, such as light track, light portrait and so on, to make the picture more dynamic and aesthetic. In the shooting of night scene portrait, the main body’s skin color is dark and yellow, the color of clothes and background is not bright, and the whole picture is not clean enough. Later ideas: to create a sense of permeability, by brightening the skin color, make the clothes and background bright to achieve transparent and clean effect. < / P > < p > the above are the main points of night portrait shooting. Of course, portrait photography seems simple. There are many skills to learn and master from the selection of clothing, props, scenes, models, models’ postures and the final stage.
