With Halloween just around the corner, this week we have prepared a special edition of Photos of the Week featuring nighttime images. Undoubtedly, this effect is among the most spectacular and difficult to achieve in architecture photography. Working in the absence of light is not a simple task for photographers, but by playing with the artificial lights in buildings (and, usually, some dramatic HDR effects) it is possible to achieve adequate exposure for incredible results. Below is a selection of 15 images from prominent photographers such as Ketsiree Wongwan, Laurian Ghinitoiu and Philippe Ruault.

This August 19th is World Photo Day, which celebrates photography on the anniversary of the day on which France bought the patent for the daguerreotype, one of the earliest photographic processes, and released it to the world for free in 1839. At ArchDaily, we understand the importance of photography in architecture—not only as a tool for recording designs, but also as a discipline that many of us enjoy. To celebrate the occasion, we decided to reveal the most popular images ever published on ArchDaily, as selected by you, our readers. Using data gathered from My ArchDaily, we have ranked the 100 most-saved images from our database; read on to see them.
