The Influencing Factors of Film Imaging Effect of Water Curtain in Fountain Construction

Water screen movie comes in a variety of forms, including flat pools, rectangular vertical screens, fan-shaped or irregular vertical screens, and 360-degree circular screens. Among them, vertical water film is more common. Today, we take vertical water curtain as an example to exchange several factors that affect the imaging effect of water curtain film.

Factor 1: Flatness and Thickness of Water Curtain

Water screen movie is the film and television images projected on the water screen, so the state of the water screen has a direct relationship with the image effect. Under the action of high pressure pump, the water curtain generator ejects huge fan-shaped water curtain. Under the action of jet pressure and gravity, it is naturally divided into dense water curtain area and discrete water curtain area. The surface of the dense water curtain is relatively smooth. Image control in the dense water curtain area, in order to better imaging effect. The thickness of the water curtain should be moderate, not too thick, not too thin. If the water curtain is too thick, the refraction of the water will produce double image, resulting in blur or distortion of the image, which directly affects the imaging effect. The thin water curtain may shake or break into mist under the action of wind, affecting the imaging effect and viewing experience.

Factor 2: Projection Equipment Performance

Now the projection equipment of water screen movie has film projector, laser projector, digital projector, and large slide equipment. Different projection equipment will produce different imaging effects. However, the same projection equipment, because of the different performance, will directly affect the imaging effect. For example, digital projectors, high lumen projectors, imaging effect is better than conventional low lumen projectors.

Factor 3: Chip Source Programming Method and Quality

Water screen movie size is large, some can be up to tens of meters, more than 100 meters wide, after forming the macro effect shock. Regular digital sources work well in traditional theaters, but not so well in such large projections. However, specially programmed film sources have a better image in large projection. With the development of science and technology, holographic projection technology has brought new visual experience to waterscreen films, and the projected images are clearer, brighter and three-dimensional. In addition to the above factors, the image effect can also be affected by environmental factors. Wind, fluctuating currents, ambient light sources can all play a role.
