Chroma green

 Ever wonder how people sitting at home can go to Antarctica to Hawaii to the ocean beds and even in the middle of active volcanoes? 

Yup. you guessed it right. 

It's all thanks to modern editing, specifically the use of the green screen. 

Using a chroma-green-coloured background, we can easily edit our subject into any possible location. 

Today Sir brought his chroma-green sheet and allowed us to experiment with it.
