A couple of days ago I posted an interior shot of a Serbian Orthodox church in Ljubljana, Slovenia, taken with a 24mm lens. I returned to the church but this time armed with my 14mm f/1.8 Sigma ultra wide angle. That made a dramatic difference. The graphic design of the images were infinitely more dramatic and compelling. This is another 5-frame HDR series in which the slowest shutter speed in the sequence was 1/40. I used one f/stop increments between shots, and an f/2.5 aperture with an ISO of 5000. In post-processing, I moved the highlights slider all the way to the left and the shadows slider all the way to the right. I then added clarity and vibrance to make the amazing interior really pop. One interesting thing to note about stacking images -- and HDR is an image-stacking procedure -- that since noise is random, with several stacked frames the noise disappears even though the ISO setting is quite high.
