The secret here is that what you get /is/ realistic: Outdoor places are 
usually /much/ brighter than indoor places. You just don't normally 
notice, because your eyes automatically adapt to the brightness level, 
while POV-Ray file output does not.

One way around this is to use OpenEXR file output, which can handle such 
difference in brightness, and use some suitable image viewer/converter - 
such as Lilysoft's IC - to generate standard PNG or JPG images from the 
output, with brightness adjusted as needed.

Another approach is - obviously - to adjust the brightness of all the 
light sources in your scene (including the sky, and any emissive 
surfaces or media) depending on whether you want to show an indoor or 
outdoor view.


(I'm presuming that you did your homework regarding gamma, as that's 
something that might mess things up as well. You should have 
assumed_gamma 1.0, and proper Display_Gamma and File_Gamma settings.)
