Look at the previous article has written some wrong sentences and ambiguous sentence, small modified a bit, hope to facilitate everyone to understand.

Light Trace Doodle Beginner Tutorial Alamas Original

Light Graffiti (Light doodle), also known as lighting graffiti, optical graffiti, or "light coating." It is a photographic creation that relies on an electro-optic or line light source to doodle in the air under dim light conditions and recorded with a camera. Simple to say is a photographic means of exposure for a long time.

If you're a photographer, you don't even know what the shutter exposure is. Baidu on its own to solve it. Do not dwell on this.

The necessary conditions for the light track Graffiti Tutorial :

Light limits for shooting venues

Basically, the light is going to take place after the sun goes down, because daytime light is unlikely to allow the camera to be exposed for long periods of time, unless it is looking for a basement, and not affected by daylight. Guangmi (University City Campus) there is an underground car park, under the library, but, where there are mosquito bites in winter, not to mention the summer, if not more mosquitoes, it is a good place to pat the light tu.

The first time I participated in the field of collective activities----Old Guang Mei

To put it simply, if the light is dark enough, it can be painted.

Clothing requirements

In theory, light-colored clothes tend to reflect light, especially white clothes, so in order not to leave the painting the Shadow painter must wear black or dark underwear, if you are dedicated, you can dress up like a masked ninja only two eyes black. But in fact, in the environment is rich in light (such as street lamps many venues), with about 4.0 of the aperture value, as long as the painter in a place to stay more than two seconds, even if the dress is black, or will leave a group of dark shadow. So black clothes and white clothes, in my opinion, is of little significance. If you want to be photogenic, wear white clothes, if you're a painter wearing white or light-colored clothes and not photogenic, then paint the light when the action to fast, not in a place not to paint stay more than 0.5 seconds (to 4.0 aperture for example, stay time according to the venue), as far as possible by the way back and forth to paint, Either use a small circle, or find a darkroom. Outside the racket environment in one place stays for more than 1 seconds basically has the residual shadow. Of course, light-colored clothing is a reflection of the flashlight and increase the likelihood of the occurrence of the shadow, dark clothing is relatively not so easy, but this does not mean that the dark clothes of the painter can stand motionless in one place.

Clothes are not the key to creating a shadow, see how you move. There is also the intensity of light on the site itself.

Number requirements

As long as there is equipment, a person can also be painted (I was alone to steal Huan class ...). But the need for late synthesis, especially to take a lot of graffiti content of the picture.

Generally speaking, the group of 3-4 people is more ideal.

If it is big collective activities, it is easy to confuse, and finally easily split into several groups to play each. What you need to know is what you're doing for the group, it's about looking for the object. is to play to enjoy the absolute OK, is to learn the exchange of light traces of the also OK, is to carry out the creation of that is very not ok! unless the team has a commander, everyone has rehearsed, have a clear purpose and theme, then OK. This is like a large orchestra, which requires a command to grasp the rhythm of the whole team in order to play good music. You can imagine what a band does not command what the situation, play the piano, playing the flute flute, beating drums, chaos mess. The same is true of collective light coating.

This is organized undisciplined chaos scene, a said play A,b said play B, listen to listen to the last or play their own.

If you are to create, 1-2 people more appropriate, a person is very clear what they want to do, many people can give some advice, auxiliary shooting, this is enough. More people, easy to mess, because the light is not painted like paint, it is in a 3-dimensional space, positioning is very difficult (how hard it is to know), especially to carry out some complex graffiti, it is best to separate local to draw, a picture, finally PS in a picture.

If there is a certain amount of light painting experience, want to carry out exploratory experiments, 3-4 of people's small combination is good, 3-4 of people come out of the idea of easy to produce some unexpected harvest.

Canon G7 15 seconds exposure aperture How many forget it seems to be 4,

So the novice, undoubtedly participates in the collective light coating activity is the most effective shortcut. On the watercress to find out what the same city of light painting activities.

Tool Requirements:

Tripod (most critical)

People with common sense of photography know that a long time exposure requires a tripod fixed camera, so the picture is clear. In fact, do not use a tripod to paint the light is not no good, but the effect of the film is residual shadow, but, sometimes can take some unexpected effect. The only thing you can be sure of is that you don't need a tripod to get rid of the characters, even if you leave a flash, it's just a remnant, unless you like the special effect. As for the front curtain sync or the rear curtain sync flash mode, see the scene needs slightly. So for the new light-coated novice, no matter how bad your camera is, no matter what your technology, a tripod is always the first thing to do.
