Steampunk is a fantasy genre that that inspired by industrialisation of the 19th century, steam propelled but sophisticated and advanced machinery, etc., into a retro-futuristic vision of a parallel world. Steampunk motifs are common in Japanese anime, computer games, literature, movie industry, and even fashion. This image is a steampunk culture inspired HDR based and photoshop and lightroom manipulated image, with additions od layered textures for creating a unique look and slightly post-apocalyptic feel, and it is a staircase leading up to a footbridge tunnel leading to Makuhari Messe.
Just for a comparison, I am posting an original image to your right, and ready finla HDR image below. The right-hand side photo is a neutral exposure, which should illustrate how much fun image post processing can be.
Aslo, check out my video tutorial on YuoTube in which I am showing how did I edit this photo.
