S Ignacio, Rome, Italy

@Ina: Thank you! Except some image rotation I did no post-processing, the light in the church was quite right :)

@Michael Skorulski: The impression of looking into an open sky is indeed overwhelming, the only church I found even more spectacular was Il Gesú.

@Craiger: It is! Interestingly, these churches look rather plain from the outside (except from the portal). The glory is indoors, a completely different concept from Gothic churches that broadcast their impression both externally and internally.

@Steven: And it is just the second most important Jesuit church :)

@danthro: The effect is remarkable - these paintings are quite large and cover the whole ceiling.

@Michael: Ja, die Barockmaler hatten's schon drauf :) Und die Jesuiten konnten es sich leisten. Aber im direkten Vergleich zur Hauptkirche (Il Gesú) erscheint Sant'Ignacio geradezu schlicht.

@EjHowarth: Having seen this I wondered if I should try something like this at home, but I eventually refrained from doing so :-)
