my shadows are not clear in my nighttime rendering

[Anonymous]

It took 21 hours each to render nighttime view of my kitchen, lounge and dining room. My shadows are not very clear. I cannot render these views again. how can I fix this.

I don't have a solution for you if you cannot render these image again, but I am curious why it took you 21 hours to render each of these views. That's extraordinarily excessive.

what i meant was that I don't want to render these views. I can render again if shadows can appear better. My views do have shadows but very very dull nearly not visible. I just want to enhance them. If you can let me know how to enhance shadows in rendered views then I can work o that.

          Rendering time was so long because I rendered my night views with best quality option

Given how washed out that ceiling is, I suspect the lighting is far too intense.  All those smooth and light colored surfaces would reflect the light into all the corners and recesses, reducing if not eliminating any shadows.

there are only six 100 watt fixtures on my kitchen ceiling. I will try to reduce the intensity and then render it.

          Secondly is there any way to Switch On only those lights which are in the view I am rendering. Maybe it will reduce my rendering time. When I rendered my night images total number of artificial lights are 137. It took very very long. How should I render my views again.
