1. What is a water curtain film
The water curtain film is made by a high-pressure pump and a special water curtain The generator sprays water from bottom to top at high speed, and after atomization, it forms a fan-shaped “screen”, and a special projector projects a special video tape on the “screen” to form a water screen movie. When the audience is watching the movie, the fan-shaped water curtain is integrated with the natural night sky. When the characters enter and exit the screen, it seems that the characters take off into the sky or fall from the sky, creating a feeling of illusory and dreamy, fascinating. The water curtain movie projector is composed of mechanical device, control bracket, communication port, software, time signal interface and DMX512 interface. The projector’s engine is controlled by optical sensing, with high precision, and there are three control methods: programming control, direct control and utility program control. The water curtain is more than 20 meters high and 30-50 meters wide. All kinds of VCD discs or special water curtain films can be played on the water curtain. The film and television effects are peculiar and novel and are excellent advertising tools. Water curtain films can be installed on the surface of the water.
The water curtain is usually more than 20 meters high and 30-60 meters wide. When the water curtain movie is played, the picture has a strong sense of three-dimensionality and space. The characters seem to take off from the sky or fall from the sky. The night sky merges into one, creating a feeling of illusory and dreamy, coupled with the laser pattern, the scene is even more grand and majestic. Water curtain movies are suitable for major festivals, large squares, and theme parks.
Second, the advantages of water curtain movies
1 . The screen is huge
Generally, small water curtains are close to 10 meters in length and width and have an area of about 100 square meters; large lake water curtains can exceed 150 meters in length and can be Up to more than 30 meters, its distant view effect at night is even more distinct than the city’s landmark buildings. This water curtain can also be adapted to local conditions, such as using local waterfalls and other facilities. The super large water curtain is unmatched by other technologies.
2, various forms
relatively simple with pool plane, rectangular vertical plane, and irregular vertical plane Plane, and 360-degree annular three-dimensional. At the beginning of 2011, the circular water curtain film was officially released in Ocean Park in Hong Kong.
3, shocking visual impact
with super-power sound effects, the unpredictable laser beam is like a mirage The general scene makes the audience near the scene feel the mysterious and fantastic fairyland.
4, wide audience
Not only close up, but also far away. Of course, depending on the viewing position and angle, the effects will vary greatly. For example, watching by the lake, watching high-rise buildings nearby, watching from a distance or aerial photography, etc. In short, there is always a free way to watch water screen movies.
Three, the water curtain film’s disadvantages
1, the cost is too high
Small vertical water curtains may have the lowest cost, but the imaging range is too small to be meaningful. The largest, Singapore-based, fixed water-curtain landscape movie is reported to have invested more than 130 million Singapore dollars; the medium-sized water-curtain landscape that is held irregularly in China generally invests more than 20 million yuan; large-scale, single, laser effect It is reported that the investment in the water curtain performance is also more than 10 million yuan. The electricity bill, water bill, site fee, and personnel cost when the water curtain works are like burning money, and the later maintenance cost is very high.
2, venue restrictions
Can only be held in very open venues, outdoor areas, pools, lakes, rivers , riverside, seaside, or squares that can provide excellent water supply and drainage systems.
3, Time Limits
Seasons, climate have a big impact. Winter in the north is definitely not acceptable; it is generally chosen in summer, or located in tropical areas, such as Hong Kong, Macau, Guangzhou and other places in China, where performances can be performed all year round. Some weather changes will also have unpredictable effects on water curtain movies, such as heavy rain, fog, strong wind, lightning, hail, etc.
4Technical limitations
Many hardware devices need to be imported, and there are many technical limitations. Taking the three-dimensional flat water screen as an example, the power of the ultra-high-pressure water pump is limited, and the spraying height from the bottom to the top is limited; the screen is huge, and the dynamic screen such as video is played, which requires high brightness for large-scale project projectors; super-long and super-wide screen , splicing fusion technology and so on.
5, the picture effect is rough
Due to the format, the light brightness is not high, the water medium is not smooth, etc. The screen generally only looks at the macro scene, and does not demand detailed performance. To put it simply, just see the painting, and don’t be picky about color, clarity, and finesse.
