Visual effects supervisor Richard Stamos final deformed 2.39: 1 widescreen, the image on the 5K set


Do not look at "Prometheus" was so magnificent scene design, CG effects are rather high level, in fact, most of the film's scenes are shot in real structures. "P" in the building most of the scenes cold room doors in the film and television production base of the pine shoot, which also uses a number of Europe's 007 largest studio (especially those close to the spacecraft's ground hangar scene), also used in the UK's biggest stage . Titles viewfinder archaeological sites on the island of Skye in Scotland, spent a week filming the landscape of Iceland instead movie alien planet. Iceland one day have 20 hours a day, and the angle of the sun is very low. Jaworski photographer has filmed cold room doors "heating than pirate" In the tropics, he felt the sunshine cold room doors difference between the two places is very interesting. Jaworski shooting equipment in the shooting Pirates of the Caribbean "stormy" ever used RED ONE MX, the selection of the RED EPIC to shoot "Prometheus." Select EPIC is because cold room doors small, and can shoot 5K. (Although he used 5K Resolution 5: 1 compression format to shoot "Prometheus"), sometimes in order to restore the scenes details, such as water and plants, it is adjusted to 3: 1 compression format, "the first shot had converted to 2K, in order to be able to match the visual cold room doors effects in the latter part of the resolution. There are so many in a visual effects movie, with 4K visual effects budget will increase four times. Of course, we have 4K projectors, So when we gather with 5K, with 4K visual effects and other post-production work, and then use 4K projection, I want to watch the results will not be lost to a large movie screen. "
The use of a three-dimensional cold room doors scaffold 3ality Technica Atom 3-D design company EPIC cameras, Angenieux Optimo zoom complete the "P" in most subjects. In 3D shooting, the lens of the conversion is very complex, if re-adjust the 3D camera is a waste of time, so the crew prepared a four devices: cold room doors two 15-40mm Optimos zoom lens, and two 28-76mm Optimos zoom lens. Shooting also use a Steadicam, equipped with a fixed focus lens Zeiss UP, so something more portable. (Camera equipment provided by Panna Davidson London)
Generally have adopted three or four cameras. First, the need to take two wide angle, and then some closer shots. After two telephoto shooting close-up, they are easier to hide. And then we need to find the location of a third camera. This is like an old mine for this puzzle: a look at the scene, the camera placed in various places, and then behold the good effects units. Shoot a scene, when a camera is no longer working, put another rail car to continue shooting cold room doors the scene shifted. "You'll get incredible mobility. You can set up a three-stage shoot dialogue scenes with three machines, and then follow that way and then photographed segment so very efficiently."
"Prometheus" lighting principles spacecraft is to make most of the light source in conjunction with the scene, cold room doors which requires the art teacher Arthur Max coordinate. cold room doors Many sources cold room doors or direct lighting, cold room doors or is hidden in the wall or in the corner cold room doors of the floor, ceiling recess. cold room doors They set up in the spacecraft's wing cracks LED lights, floors and walls of the groove is still in the layout of the LED lamps and fluorescent lamps. A standard LED panel is roughly equivalent to a 500 watt incandescent light, which can greatly reduce energy consumption. Evans said the gaffer, lighting fixtures they also placed behind the grating, also made temporary vents. Many of the scenes into almost all use LED lights, and some fluorescent lamps. Jaworski said:. "The film is suitable for modern lighting our spacecraft designed many complex controlled by dimming the lights when he added an LED light or look at the bottom of light on the console, he I will use the same set of lights. "(shooting with light equipment provided by Panalux company in London)
Uncle Ray Evans Evans Ray Evans is "Alien," the gaffer. "When I got the job, I can not wait to tell him, he also wanted to see the scene layout. And when he saw the spaceship, he exclaimed with LED lights we actually do it all!" "Alien" is undoubtedly the pioneer work of science cold room doors fiction movies, Jaworski said: "Ridley insisted shoot real picture, at the time, everything is more trouble, so he had to use the projector chasing light, soft light settings may be 2K lamp, light film. In "Prometheus", we use better technology continue this way. "
Jaworski in "Prometheus" on the first floor library with a mix of large spacecraft variety of color temperature of the light source, the spacecraft in one vast scene of the door is a film and television production cold room doors base in pine backlot of a tall green screen shooting. There is a library inside the spacecraft mixed the lamp tube, LED lamp is fitted in the engine cabin, a group hanging cold room doors on the lift at the bottom of 4K dysprosium lamp simulates the spacecraft work lights. In fact, the spacecraft has been a "traffic jam" state, with a variety of lifts for hanging off the door of the cabin, hanging lamps dysprosium, also covered with shade cloth 12x12 meters to prevent the sun shine on the actor and green screen. When shooting with a green screen interesting phenomenon is that when you spend more than to illuminate the characters time to give a will "does not exist" in the screen lighting!
James Gorman Jaworski has been involved in 3D Pirates of the Caribbean series, "Prometheus" is the parallel style shooting, referring to the integration of the left and right of the image needs to be done at a later stage. Parallel to shoot so that the visual effects look better, because cold room doors those engineers do not need to be adjusted to compensate cold room doors toe convergence camera. (English Reference: because those artists do not have to compensate for keystoning of toed-in, converging cameras.
Visual effects supervisor Richard Stamos final deformed 2.39: 1 widescreen, the image on the 5K set a 4,800x2,000-pixel image window, taking into account the convergence cold room doors adjustment and reconstruction of some vertical cold room doors space In the left side 100 pixels. 5K after copying the original, using RedCine-X software to verify RMD file, and then determine a lens converge each set (Goldman provided). The metadata will be sent to the data station, where officers will be responsible for post-convergence color correction and 3D samples. The final 3D convergence is completed, while the final movie is done.
