[Highlights and shadows]

I looked through the form and did not see this topic. I am trying to shoot real estate 360 photos for a walk through presentation with a Ricoh Theta V. Interior is dark wood while there is snow on the ground outside, creating difficulties with exposure (bright light from windows and dark interior). I tried stacking as well as highlight and shadow adjustments without adequate success. A similar project was successfully done by someone else at a location nearby, so I know it can be done. Suggestions?
