Hi Siddharth,

This is generally used in product / portfolio or any genre which is shot under controlled situation where there is constant light source. They include a grey card in the 1st sample frame and later in post processing the set the RGB value of that grey card to 128,128,128 which in turn ensures that all colours are represented appropriately. Then they use those values to all other images shot in that light.

Rgds,
