Recently I had the opportunity to commute in this recently inaugurated train station, with quite a unique design. It consists of an island platform, 140 metres in length that lies some 20 metres below the surface. The main feature of the station interior is the glass brick elements which are lit from behind to give the impression of daylight.
Although the light inside is not as bright pure daylight, the use of HDR helped to convey that impression, possibly something that the designers of the station envisioned when they created it.
For this particular photo, only three brackets were used, processed in photomatix and finished in photoshop.
