Thanks To all for Replying. really appreciate Your valuable comments. @Ryan Nelson No Sir, i am not working with open exr files. i usually save the renders in Targa. i need to concentrate more on my white balance den. that is the ultimate solution i guess.
@Tom Livings No sir, i am not talking about Scandinavian Interiors in particular.. its just about whitish look many 3d artists achieve in their interior renders. after reading all the comments i am quite sure that i am wrong in my white balance settings. i will surely work on it.
Thanks again for your valuable comments
