Andrew Varlamov: Gostiny Dvor and Nevsky Prospekt Behind the scene : how this panorama was made Let me say some words about technical conditions of photography. It were strong snowfalls since March 17 till March 19, 2005. Early morning of March 17 was so cold that lens of my camera became foggy after pair of shots (air temperature was -10 degrees of Celsius and humidity was around 85 percents). Panorama You see now was made in Saturday evening in pause among snowfalls. Air temperature = -4 degrees of Celsius, Exposure time = 1/20sec, F-stop = 2.8, Focal Length = 7.8 mm, Sensitivity = ISO 400, Camera = PENTAX Optio 450. Return
