I guess you've heard about the movie 'Gravity'? It received seven Oscars. To be honest I personally found it a bit boring and I fell asleep watching it, but I am not a movie expert and I often fall asleep in the cinema anyway :-)
In the original movie Sandra Bullock plays a brilliant medical engineer on her first shuttle mission, with George Clooney as a veteran astronaut in command of his last flight before retiring. But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving the two completely alone—tethered to nothing but each other and spiraling out into the blackness. The deafening silence tells them they have lost any link to Earth... and any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go further out into the terrifying expanse of space.
In our movie (below) Baba plays the main part and I think he is doing brilliantly :-) What do you think dear Atria? Could he replace Sandra Bullock?
Imagine that the video of Baba was actually digitally cut off its green background and place into the digital movie background. Well... Baba's movie is a movie with special effects :-)
Professional name for this technique is chroma key and it's has been used heavily in many fields to remove a background from the subject of a video (or photo) – particularly the newscasting, motion picture and videogame industries. A color range in the top layer is made transparent, revealing another image behind.
Do you know how this movie was made? It was made using a very popular green screen technique. Basically Baba suited in his astronaut costume was placed against the green screen and he was acting like there was a space landscape behind him and as he was on the mission to save the humanity. He was trying to open a space shuttle door unsuccessfully and he had a free fall into space in the end. He had to imagine all that as of course nothing was actually happening on the green screen. The space behind Baba was added later and it was all created digitally.
I am sure you have watched a weather forecast. Chroma key technique is commonly used for weather forecast broadcasts, wherein a news presenter is usually seen standing in front of a large map during live television newscasts, though in actuality it is a large green background. When using a green screen, different weather maps are added on the parts of the image where the color is green..
