Mobile phone light painting photography course 1: principles of light painting photography

Light painting photography is also called? Graffiti This is a simple and creative photography technique, and the effect is amazing. It needs more than two friends to cooperate with each other to complete smoothly, and it needs the collision of tacit understanding and creativity, so this kind of play is more changeable and interesting. Of course, in the mobile phone professional mode, a person can do it without external force, but the reaction time is short. Therefore, in order to ensure creativity and fun, it is recommended to cooperate.

By definition, the creation of light painting photography requires the shooting equipment to have long exposure function, which is only a normal function for professional cameras. By adjusting the aperture size and setting the exposure time in B-door mode, the longest exposure time can even reach several hours, which can completely realize long exposure shooting. However, for ordinary mobile phone photography, because the aperture is constant and the exposure time is uncontrollable, it is difficult to meet the requirements and it is impossible to take a light painting. Light painting photography can be done indoors, at night, or even in dim light. It doesn't need a special camera or lens, and almost everyone can shoot with a mobile phone.

Choice of environment

Light painting photography is generally carried out in a dark environment. The main reason is that light painting photography is a long exposure process. If the ambient light is too strong, the photos will definitely appear? All white? In addition to overexposure, dark background is more likely to show the trajectory of light, and it is not easy to leave the painter's figure.

Camera settings

When using a mobile phone for light painting photography, the mobile phone is usually fixed through the tripod (if it is a fixed light source, such as a street lamp, you can also shake the mobile phone to shoot) to ensure the stability of the mobile phone. If the mobile phone supports light painting photography, such as Nubian Z9, Huawei P8, etc. , you can directly enter the application interface for shooting. If the phone doesn't support it, you can download the application. Can Android users use it? Nubian camera? , iOS users can download? Magic shutter? Both applications support exposure time adjustment and shutter speed selection.

The shutter speed can be set according to your own creative ideas, and you can choose 8 seconds, 15 seconds, 30 seconds and door B. If the light painting work is complicated and there are many people to cooperate with, you can choose door B to shoot. The aperture setting should not be too large, and it should be set according to the brightness of the surrounding environment and the illumination intensity of the painting light source. Light painting photography generally chooses the aperture below F5.6. If the exposure time is particularly long, you can choose F 1 1, F 16, F22, etc. As appropriate. Don't set the ISO sensitivity too high. It is best to choose the lowest gear (generally 100), which generally does not exceed ISO 400. Photos taken at low sensitivity can reduce noise and ensure the purity of the background.

Application of light source

In addition to conception, light source also plays a very important role in the expression of light painting creativity. Before shooting, think about what kind of effect the work will present and what kind of light source is needed. Light sources are generally divided into point light sources, line light sources and area light sources. The most common are flashlights, light tubes and light sticks. In addition, under the highest brightness, the iPad with pure white background can also be used as a painting light source. Little friends can use their imagination to create.

The choice of light source type and color plays a great role in setting off the atmosphere of the work. Different light sources and moving speeds show completely different styles and linear densities. For example, a point light source can flexibly decorate the picture, and a line light source and a surface light source are directly facing the lens, which is a large-area rendering. Red and yellow generally show enthusiasm, while purple and blue generally show cold pictures. In addition, when using direct light sources such as flashlights, be careful not to aim directly at the lens and keep a certain angle with the lens.

In addition, there is a commonly used prop for light painting, steel velvet, which can show the scene of sparks, but it is dangerous, so it is not recommended to use it in places where novices and onlookers are many.

Where is the painter? Painting? When drawing, you'd better wear dark clothes that don't reflect easily. In addition, don't stay in one place for a long time in the process of painting. Painting? Move fast, move fast, so as not to stay at work? Ghosts? The painter's vague figure. Before shooting, you can refer to the works of light painting photographers to broaden your horizons.

In the creation of light painting, you can use a variety of color light sources, and the shapes of light sources are basically divided into three types: point, line and surface. Point: Point is the point light source of the flashlight we usually use. Light bulbs, laser pens and so on are all point light sources. The role of point light source in light painting is equivalent to the effect of pen and brush, and the trajectory drawn is like the picture below.

Point: The skill of using a point light source is that when you wave, the angle of the point light source determines the brightness of the line, such as a general flashlight. When your angle is about 90 degrees from the camera, the light disappears completely. Facing the camera, the light source will be very bright. The change of angle determines the different layering of lines.

Line: The line light source is the nature of the light source, and it is a line. Like ordinary fluorescent tubes, it belongs to linear light source. There are some advanced painting methods in light painting, which use a line called EL cold light. This hairline is soft and can be kneaded into any shape at will. The use method of line light source can be packaged in one place for fixed shooting or fluctuating shooting.

Area: Area light source is rarely used in light painting. Its main property is a light box. After the production of surface light source, it can only show fixed content, and generally does not need light painting because of poor flexibility.

There are some points that need attention in light painting photography creation. Light painting usually needs to be done in a completely black scene, and the exposure time is long. If shooting outdoors, make sure that the shooting site is not exposed to other light sources, and pay attention to avoid the influence of street lights and car lights. In terms of dress, because the painter needs to walk constantly in the environment to describe lines, he should try to wear dark clothes when shooting, because light clothes are easy to reflect in the light and tend to leave residual images in the picture when shooting. If the shooting content moves greatly, it can be almost ignored. In short, the principle is to prevent the painter from staying in the picture for too long, leaving a vague movement after a long exposure? Ghosts? According to my experience, no matter what color clothes you wear to shoot, don't stay in one place for more than 3 seconds.
