First Course in Alaska graffiti light trails Masi original
trace of light graffiti (light doodle), also known as light graffiti, optical graffiti, or referred to as \It relies on electro-optical or line source in the dim light conditions, the graffiti in the air, and recorded with a camera photography. Simply put it is a means of long exposure photography only.
idiot if you are a photographer, even the concept of the shutter exposure do not know what the words themselves ... ... to solve it on Baidu. This does not repeat them here.
trace of light graffiti
prerequisites:
light filming restrictions
Basically,
######y bikini, optical coating is to be carried out after the sun sets, because the daylight is not possible to make the camera a long exposure, unless it is to find the basement and the like, are not the impact of sunlight. Hiromi (University City Campus) does have an underground car park, in the library below, but blanket, where the winter and mosquito bites, not to mention the summer, but for mosquitoes, it is still a good place to shoot light coating.
the first time I participate in group activities, field ---- the old Canton U.S.
put it simply, as long as the light is dark enough place, you can shoot light coating.
Dress
theory, light-colored clothing reflects light easily, especially in white clothes, so in order not to blur the artist painting left to wear black or dark pants, if you enough to work, you can dress up like a masked ninja reveal only two black eyes and body. But in fact blanket, more abundant in ambient light (such as street lights and more space), with an aperture of around 4.0, as long as the artist to stay in one place more than two seconds, even if another black dress, or leaves a group dark blur. So black and white clothes, clothes, and then my personal opinion, not very meaningful. If you want on the mirror,
ralph lauren bikini, wear white clothes on, when you are the artist wearing a white or light-colored clothes and not on the mirror, then the picture painted when light moves faster, can not stay in one place does not paint more than 0.5 seconds (in 4.0 aperture, for example, length of stay according to venue may be), try to walk the way back to drawing, or with a small aperture, or find a darkroom.外拍 environment to stay in one place more than 1 second, basically a blur. Of course, the light-colored reflective clothing and flashlight will cause increase the probability of the generation of blur, dark clothing is relatively not so easy, but this does not mean that it can paint a dark dress standing motionless in one place.
clothes are not the key to produce portraits blur, to see how you a move method. There is space itself, the light intensity.
number of requirements
as long as the equipment, a person can light coating (I own Touhuan class is ....) But the need for post-synthesis, in particular, to take a lot of graffiti content map.
3-4 team in general is ideal.
if it is large group activities, it is easy to confusion, and finally easy to split into several groups all play each. It should be clear that you take part in collective activities aimed at doing here is to find the object ok, is the play's enjoy absolute ok, a trace of graffiti to study the exchange of light is also ok, is for creation of that very not ok! Unless the team has a commander in chief, everyone rehearsed, with clear purpose and theme, then ok. It's like a big orchestra playing the same need for a command to grasp the rhythm of the whole team to play the good music. You can imagine what a band did not command the situation, playing the violin in playing the violin, flute flute, drums the drums, buzz mess. Collective optical coating is the same.
This is no discipline of organized chaos, A say to play A, B that play B, to listen to listen to finally play their own.
If you are to create a 1-2 is appropriate, one doing very clearly what they want, more than one person could give me advice, support shot, that was enough. More personal, easier to chaos, because the optical coating like paint coating, it is in a 3-dimensional space, the positioning is very difficult (how hard it tried to know), especially for some complex graffiti, the best draw local or separately, one by one shot, the last in a graph in the PS.
If you have some experience in optical coating, to pilot exploratory small 3-4 combination is a good combination of 3-4 out of ideas easily lead to some unexpected gains.
Canon G7 15 second exposure aperture seems to forget how many 4,
novice so it will undoubtedly take part in collective activities of optical coating is the most effective shortcut. What city Douban look on the light bar coating activities.
light coating activities in Guangzhou
tool requirements:
tripod (most crucial)
photographic common sense knows that a long exposure is needed the camera on a tripod, so that only a clear shot out of the picture. Indeed blanket, without a tripod is not making light coating not only beat out the effect of blur-like, but the blanket, and sometimes be able to shoot some unexpected effects. The only certainty is that, without a tripod blanket, the film is not clear figures, even if you have left open the flash is just a blur, unless you like the special effects. As a former curtain sync or second curtain sync flash mode, see site requires slightly. So for the optical coating of the novice, no matter how bad your camera, no matter how skilled you like, a tripod is always the first necessities.
I use the device
Canon 350D SLR Canon G7 tripod mini tripod (mainly to G7 in one place when the flash folder with)
camera
the best friends of course, SLR, SLR generally has b doors, but doors need to wire b, under normal circumstances few people buy a remote control. . . . . . I use a Canon G7, 350d SLR, wireless control. Mainly used for 30 seconds 15 seconds exposure and exposure shutter.
not to say that we must take light coating Figure SLR,
louis vuitton bikinis, the card device also can shoot, put out the effect of how to shoot, it depends on the quality of the camera itself (the author of the G7 effect than the 350D SLR even better), and the camera's own settings like white balance conditions. The most crucial is whether your camera has the ability to long exposure, that is at least 10 seconds exposure capability. As well as low ISO sensitive.
external flash
sometimes need to take some exposure, such as optical character you want to make with James, you can choose an external flash, you can also use the camera's own flash, but I think the external flash free Select the flash point, good control, (for example, in a 30 seconds exposure time, you can flash the main character to a side, and then painted the other people in the auxiliary light) and can be many times the flash can also be carried out as a special light source Tu, shoot-like flash of light painted pictures.
No external flash
not shoot, a small card with the camera flash can also act as the role of an external flash, if you do not have many cameras, only one camera, then led by white you can shoot flash torch light coating effect was strong, with the addition of adding a colored glass, the effect will be a little better, as long as the flashlight to the camera photos, to remain intact to shoot the kind of effect, and placed Well according to how long, vary.
the middle of the green effect is taken out, such as the above method, not using the flash, I have been holding a white classmate led to add a green Sprite bottle in front, facing the camera, exposed 15 seconds has been fixed to out of this effect.
light
luminous objects as long as they can, can bring light coating, I use color led lights, led color light bar, led color light, led rechargeable flashlight. Lights in the toy store to find, if you know you can own electric welding style lantern (which interest if you have it). Haizhu Square, Guangzhou friends can go to the wholesale market, where to find toys, N more luminous stuff.
combination of tools
color transparencies, glass bottles, plastic bottles, some of Ling microscope can produce physical reactions and light as a luminous body can be a combination of tools to use, I currently use a combination of tools are installed about 1 / 2 Sprite bottles of blue water (ice mint flavor - unfortunately was discontinued), uniform cover of green Sprite bottles of green tea (plain), Coca-Cola poured covered vase (right red one), equipped with a yellow transparent film Blue Pine Tianquan small bottles; Sprite bottles (green bottles); also bought two new mineral crystal ball (has not been put to use them).
Sprite bottles of water in Riga
purpose is to allow the water to the torch of light refraction, which can shoot a strong sense of some of the lines of the actual situation, rather than light, like a flashlight dry. As long as the flashlight on the bottom, according to the bottle, there lived two things with one hand shake (you like to use both hands too), you can immediately feel the light is reflected off of Xun Li, turn off the lights do not believe try. Although the cut-off blue-bottle, the green bottles of flavor is not bad.
effect after turn off the light
Sprite bottles filled with water that is the effect with Canon G7, each exposure of 15 seconds, aperture of 2.8, a total synthesis of 12 were taken, I am single operation, dressed in white (also not see what's blur, so do not necessarily to be dressed in black)
This is the water bottle shot with red, the camera's white balance setting had a yellow, is able to produce similar effects of the fire because the role of water in the bottle, Canon G7, 15 second exposure,
sinful bikinis, 2.8 aperture, were respectively Synthesis of 6 shooting, one man operation, dressed in black
Well, so much that graffiti should have some light track end of it
the following Blu-ray writer with a simple effect of thousands of birds, lectures and demonstrations throughout the single optical coating operation.
final renderings
First, install a good tripod, choose the right camera angle, the first general idea about what to draw your kind of map, those pattern trajectory you have to do what, and how light wave are To advance to a good, easy to mistake that beginners start with great interest, to pick up the torch to want to make Bo do not know what to draw patterns, start shooting for around a blind tweet tweet of a symbol or pattern from an unknown, although Sometimes these patterns will be quite mean, but then, after all, is a small probability event, in fact, the difficulty of optical coating operation more difficult, the main difficulty in spatial orientation difficult, there is the effect you want in the end, you will want to better According to the environment to set the shutter and aperture, and then shot. All this requires the accumulation of experience, not necessarily you want to come to definitely do it, so be sure to play more light coating to try.
a brief look at what thousands of birds.
Chidori jutsu is a lightning attribute,
girls bikinis, inside the card in the Naruto own unique skill, just like the hands of thousands of birds gathered in the shape of lightning as a group.
(if I have clothes, then Kakashi ...)
into the shot and then, I use the SLR 350d, select the manual mode, aperture 22,30 seconds exposure, took a total of four, the last ps synthesis. Because white light is dead, so instead of using blue light.
the first phase, the first in the positioning point (center position of the flash that the camera-like illumination) Rated 4 seconds to produce a flash-like effects, then remember this position, that anchor point, and in turn from the position point to draw 7 lines, each line with an average of 3 seconds to draw.
second without first freeze to you, directly after the start of turn 4 from the anchor line to draw an average of every 7 seconds.
shaking in the anchor light polish on the surrounding environment for processing.
touch up treatment for people, lights according to the fixed stand 30 seconds. (Single trace of the limit of light here, when their main character as a modification of the need for additional light when the trouble will become very passive. Because no one else to help you, you have yourself to think of a way.)
finished shooting, followed by synthesis stage.
Synthesis of light graffiti
track is very simple, so simple did not have to be simple ... ...
ps open in four
Figure
which map the first map, after which it does not matter, as long as all copies of the four map layers in the same background together, for example, the first figure I will copy to the second diagram above, generates a call graph Layer 1 layer, then layer blending mode to lighten, then the first diagram with the effect of the second map will be added together,
choose \
Finally, some minor modifications, to polish the first four characters of the light source according to p out of it (the case of 4 photos in layer 2), then there are two ways, first is to use Rubber tools to wipe, the second is to add a layer mask in the
Add layer mask, the gradient tool and then black in the mask at the fill. The role of the mask is actually a mask to the layer block out unwanted parts without affecting the other layers.
Ok, it's that simple, no deduction plans, they do not tune it that, unless the shot was not performing need to be transferred, where I just make a simple model, as long as your camera point of view has not changed, basically synthetic lights only need to change the layer mode on the line, the other at most add a mask and mend some, that's all.
Many people have questions about this map, that is not self-immolation, I believe the article from scratch, if we patiently to see here, then, will feel that suicide is not necessary, and the pile fire p up from the material inside, so in addition to real film, you can also add in the real basis for making a number of other elements, so that works more vivid.
novice will encounter the first problem
What problems
blanket, that is, the beginning do not know what the painting, how painting. Well in fact, people are not born with any city, things are back out through exploration, especially to light painted this very practical activities, playing a lot of lighting and photography skills have a certain understanding, will find the feeling, and there is no fixed routine of light painted, play totally free to spend, what you can come up with new ways it is your talent, for starters, you can choose someone else's painting model, or recklessly also, but must first reflection, was likely to have a harvest.
light coating to be considered a matter of fact quite a number of things, such as site characteristics,
bikini 2010, light control, light trails effect of different aperture, shutter scene effects of different light source itself, the shape effect, different gesture of lighting effects (micro perspective), physical coordination, spatial orientation (the most difficult to control) and so on. Taking into consideration all factors, in addition to the details of making the rich light coating. But if you are a novice, you can not bothered, directly to let go of playing it, playing a lot of experience and accumulated there.
light trails before work just to play
help students \
immediately ran to the door (still in the dark to prevent light encountered in the process of moving a tripod), turn on the lights, the characters hold the position without moving scenes and characters to achieve exposure. In fact, if one more person to meet up on the convenience, but also can be used for flash, but the first play of light painting, many of the details will be ignored, and only care about the music. This picture taken before the n-sheets, because there is no experience.
I was shaking, not knowing the painting Han.
to Akira.
thousands of birds, the first attempt, because the feet have been standing, only the hand is moving, so the body has blur.
Finally, enjoy the occasion to want to go out a spoof of the map. . .
for the venue, I would like to add, indoor and outdoor has its advantages and disadvantages, but I just like to pick the tile, as can be reflected. .
\
formal tests before the shooting, the site
specular reflection. . . (This is the reason why I'm going to the toilet, ha ha ha)
In fact, I want to say is that you can take advantage of the conditions of light painting (site characteristics), can also create conditions (combination of tools), complement each other.
slightly better, write it slightly, have any questions, please note that I will try to answer, thank you.
