A view of a room lit only by window light

This is a room lit only from the light appearing through the windows. I had gone to a resort called the Shiva Oasis in Behror, Rajasthan for the weekend, and in the daytime I saw that the main lobby did not have lights on, only the diffused sunlight from the windows.
This created a good effect. I tried with and without flash, and I think that the above picture without flash gave the best effect.
