Architecture Photography

The photo shows part of a large spiral staircase in the Leitz headquarters in Wetzlar. The main colors in this staircase are white, so there wasn't much color work to be done.
I added the lady in the lower right half of the picture and the sky with a plane in the middle of the picture.
I cropped the motif so that the curves of the spiral staircase, at the top right and bottom left of the picture, end at the corners.
The subject was photographed with available light, without an additional light source, with a Canon EOS 5D, Mark IV at aperture: f/5.0, exposure time: 1/200 sec, ISO: 200, focal length: 16 mm.
The image was developed in Camera RAW and further processed in Photoshop CC and the Nik-Filter.Colleection.
