Quote - i think its a little to dark.. there would be more light IMO

Not if you were using a camera in the real world.  Assuming that render is the equivalent to a scene in bright sunlight, the only way to get the image the way you think it should be would be taking multiple exposures and blending them into an HDR image through post-processing.

A few weeks ago I took some pictures of people walking on the ice (I live in the Arctic).  Nice sunny day, so there was a ton of reflected light.  Yet if you look at the images, there are parts of them that come out as totally black, which was impossible given the lighting conditions.  The problem was that if I set the camera to get the contrast in the shadows, the lit areas were completely washed out.

You don't see this when you look at something directly because your eyes are constantly adjusting to allow different levels of light in while your brain is combining the signal, post-processing in effect, to create that HDR image.
