Spiral love
Anybody who is following my works knows I have a soft spot for spiral staircases, here are some related posts:
This spiral staircase is in in the interior of the tower of Constance in Aigues-Mortes (France). This has been shot with my iPhone 4s and the Olloclip wide lens.
The app used to shot the image was Pro HDR, cropping and adjustments were done using Snapseed, further editing was done using Dynamic Light, Blur FX, Modern Grunge and PhotoToaster.
