The charming charming hills of Kodaikanal. Hills look good on a blue shot. One could use a blue filter on the lens to acheive this, or could use another trick: fool the camera! Set exposure such that you were shooting in Fluroscent light (like a tube light, for example), and use this setting outdoors to create this effect. I did not have a blue filter, since the shrubs in the foreground are still green in color!!
