Evolution of Film Making

Film making have been a trending medium into mass,and made a revolutionary mark on future.The term “digital film making” can refer to a number of different processes and techniques used in modern films, and can simply mean the use of digital cameras, or more extensive digital aspects such as characters and environments created completely within a computer.A new revolution is stirring as 3D releases, DSLR cameras and free Internet distribution (YouTube, etc.) bring the digital age of film making to Hollywood’s to a local film production front door.On a lighter note,movie making have been highly socialized with software and computer appliances.Movie making digitally had moved ahead in a dazzling way,as the technology advanced into modern software era.

To,speak more about movie making evolution,we need to travel back to end of 19th century."George Melies",a man who spent his life studying of better film making practices invented Matte's process.In 1898,the film named "Four Heads are better than one(Un Homme de Tetis)" has been an initiative to what exactly today we have been enjoying the 'green screen visual effects'.The process of Matte's shot has been where combining different film making shots into frame has been a master piece of bygone period.Matte's process actually is executed by using a piece of black cloth or black paint on the surface where one want to apply an effect.Later on various shots are combined to the orginal shot,finally leading into a double exposure shot into one frame.Later on the same technique is used in "The great train robbery(1903)".

The next technique or visual trick to create false realities evolved during early 1900's which is called as "Glass shot".Where a picture is painted on a glass.and it is placed between the subject(Actor or Scenery) and camera.The idea of "glass shot" was developed by "Noram Dawn".Later Matte's process and Glass shot are
combined by painting black color on glass.This technique is used in films like "Last days of pompeii(1935),Ben Hur(1959),Escape from New York(1981)".

However,drawback in matte's process is the camera have to stay perfectly stable and cant cross the matte's black spot.So,replacing this "Travelling Matte's Processing" invented by Frank Williams.Further William's process is used in the film "Invisible Man(1933)"

But,in William's process the shadow of the subject moving is lost.Substitute for this is Dunning process(1925) by C.Dunning.In Dunning's process,blue background is present.And the subject of the shot is exposed with yellow color. Following this,using dyes and filters both are splitted to invent the actual shot.This Process is used in "King Kong(1933)".Dunning Process happened in black and white films only.

So,the other process using "blue screen" was employed in "The thief of Baghdad(1940)".Using the three strip process the subject is processed,and the reason why Blue was used:This color appears farthest in appearance from skin tone's.And further using OPTICAL PRINTER all the three strips are involving the amalgamation of subject and removing the blue color which claimed Best effects:Academy award in 1940 year.Woefully,this process it too time consuming job.

And later on Hollywood experiments involve "Yellow Screen","Ultra Violet Matte" consists of powerful sodium vapour lights behind the subject.Sodium vapour emits light very effective.The wave length of sodium vapour is 589.3nm highlights the subject at its best.Using the same technique Hollywood witnessed some best movie like "Disney:Parent Trap","The Absent Minded Professor","Mary poppins(1964)"

But,you would be wondering where did today's Green Matte's process kick-start.Yes,When Digital Film making pioneered the Film making technically there was a need for better Technology to take over the Digital format camera outputs.
So,Why Green:
-It requires less light
-Brighter in Electronics
-Works well Outdoors
-Less common in costume of a subject 
Using Bayers Pattern where luminescence is effectively presented by Green color
than blue and red colors. Also,Modern digital camera technically capture the green color impact ultimately.

However,Blue and Green are being used in contemporary film making techniques.Now Software keyers and Motion controlled cameras define the Modern Film making era.And fact is that modern films are highly reliant on "Computer Generated Imagery(CGI)".So,modern Film makers are provided with the best and mighty tools,techniques.Right from evolution,every film viewer never cared these techniques,physics and light theories.All he cared is what happens on the screen.So,all you movie making aspirants,work presenting ur story and script at your best.

IBM LinuxONE : Execute everything with Linux Mainframe!

IBM on 17th August 2015 announced the launch of IBM LinuxONE Enterprise level which runs on Linux.  As we all know, Linux is known for its security and high-end flexibility, the latest one’s will definitely be cynosure.  The server variants includes LinuxONE Emperor for large enterprises and Rock hopper for mid-size businesses. LinuxONE Rockhopper can efficiently support small scale infrastructure at lower costs. IBM Mainframe is designed in a subtle way, with a capability of handling 8,000 virtual machines, and millions of active users it would be simply Uber. To be more specific, LinuxONE is capable enough to handle 30 Billions RESTful Web transactions per day.       Now, what is a RESTful transaction??! . While REST means Representational State Transfer, this is an architectural style for hypermedia networked application design; it mainly is used to build modern day web services which make things easy, with their lightweight, maintainable and compatible dimensio
