Quote - Now I ask you which of the 2 images is more realistic?

For me the first, but I'm not a big expert on lights.

The second is more realistic.

What you seem concerned with is exposure. What I'm concerned with in realism is not exposure, since exposure levels can be anything you set them to, even in real life.

What is unrealistic here is an expectation that a properly exposed interior and exterior are simultaneously possible. This is only possible if you manipulate the image, as is done in real photography.

In this room, except for points near the windows, almost all the sky light is obstructed. As well, only small patches of sunlight enter and hit the floor. So, overall, about 1/10th of the light that is hitting outdoor objects would reach this interior. The outside is at least 10 times brighter than the inside. At least.

I find your brighter image looks totally fake to me. In that case, if the inside was exposed enough to look bright, then the outdoor part should be completely blown out, mostly white.

There are hundreds of photos demonstrating this.

We don't have a camera "exposure" setting in Poser. To get the same effect, you cannot make the camera more sensitive - you have to make the light brighter.

Set the infinite light that is your sun to 800% intensity.

Set the sky dome to at least 500% intensity.

Then you will begin to approximate a realistic indoor photograph that is well lit.

Or - put some lights on inside - that's what real photographers do.
