This was pretty impossible. The glass door was full of bright reflections and the interior of the church was dark. My husband tried to block the reflections while I tried to capture the interior of the church. This was the best I could manage, but I'm posting it because I thought the ceiling was interesting.
For images on the architect's site as to how it used to look and what the interior actually looks like, see http://eloepiteszet.hu/?q=hu/makovecz-imre/petohenye-katolikus-templom
