Spiral staircase

This is the spectacular spiral staircase in the Monastery of Melk about an hour west of Vienna, Austria. Unfortunately, photos are no long allowed in this magnificent monastery and cathedral. I have no idea why organizations prohibit photographs; it makes me angry that they do so. In the past, tripod were prohibited, which is understandable, but the prohibition against photography seems to have no rationale. I took this with a Canon 14mm wide angle lens, and the settings were 1/60, f/4.5, and 400 ISO. Note the extensive depth of field even though I was shooting with a fairly large lens aperture. I used natural light, and in post-processing used the 'vibrance' slider in ACR to embellish the colors.
