The Basilica Cistern is a relief from the heat of the day. As I descended the steps into the underground chamber, the rows of columns seemed to stretch far off into the distance making the chamber appear larger than it is.
The dimly lit walkways are bright enough to see where you are walking but not enough to compete with the up lit columns and ruin the atmosphere. The red light projecting into the shallow water is a nice touch and illuminates the carp and goldfish that swim in the clear water.
I needed a wide angle for the field of view and so swapped the lens to the EF 17 – 40 F4L.
Taking a branch off the main walkway, people are gathered around a column, poking their finger into a hole whilst their companions take pictures. At the end of another branch way are two columns which are supported by carved Medusa heads. The air of ammonia suggests what is dripping down onto the wet floors and so staying here for too long is not recommended.
