not get sufficient light in render image

[hina chitalia]

Hi all,
I render my scene after setting of light.but when I render the image come it looks dull means not sufficient light is there. Many time I tried with increase the intensity & some different setting however the result is same I can't understand why it looks dull

Attach your scene here. best option for you. other we have to continue our conversation for multiple times!

definitely post more info...

Is it an interior scene? Maybe your glass material needs to have affect shadows ticked and set to "all channels".
Are you using the Vray Frame Buffer? Maybe you need to tick the sRGB button at the bottom of the window.

There are many other possibilities.

I have 2 side table in scene & on each of that I place ,
'king of checkers game ' I assigned 2 side v ray material with omni light & corian stone materia. when render 1 object look o.k but another one looks gray.I also tried to place light near that object but still same problem .
