The Theseus Temple is located at one of Vienna’s parks in the first district close to the city hall. The temple was built around 1820 as a piece of art and has recently been renovated and received the complete white paint.
The photo is a three image HDR taken during the blue hour after sunset. For night HDR potos, I prefer to use Nik HDR Efex Pro [Homepage Link] as it produces better and less noisy results. Then I used Silver Efex Pro to convert it to black and white. Silver Efex Pro[Homepage Link] provides much more control over the conversion process than Aperture or Photoshop.
