The story of this photo:
This HDR vertorama was taken in the Basilica St. Martin in Weingarten, Germany. This wonderful church was built between 1715 and 1724. The white interior creates a fantastic light, and when the sun is shining, this place lights up. This is a classical example of a scene that requires HDR. In a normal shot, you could never capture how the sun shines on those pillars without the rest of the shot being hopelessly underexposed.
While processing this shot, I discovered that my usual HDR Vertorama technique lead to a strange problem: Usually, I stitch the 32bit HDRs in Photoshop before the tone-mapping. However, I found that Photoshop drastically loses details in the highlights during this process. I tried it with this shot and the spots where the sun shines on the pillars became big ugly white blobs without any chance of recovering details. The information in these spots was just lost. Strange! I did not find any explanation or a way to cure this yet. Photoshop just mysteriously loses this data. If you have an explanation, let me know. To avoid this effect, I have tone-mapped the individual images first and then stitched them in Photoshop.
Take a look at my "HDR Cookbook"! It contains some more information on my techniques.
How it was shot:
> Taken handheld (Read more about the technique!)
> 5x3 autobracketed shots (three exposures each with 0, -2, +2 ev)
> Camera: Nikon D90
> Lens: Sigma 10-20mm F3,5 EX DC HSM
> Details can be found here
How it was stitched and tonemapped:
> Created 5 tone-mapped images directly from the RAW files using Photomatix Pro 4.0 (Detail Enhancer)
> Saved the images as 16bit TIFs
> Stitched the 5 TIFs using Photoshop
How it was post-processed:
> Post-processing was done in Photoshop
> Topaz Adjust on the entire image to get back the colors and the details [details]
> Topaz Denoise (more aggressively on the white walls) [details]
> Topaz Infocus on the entire image for sharpening
> Saturation layer on the white regions (desaturation)
> Saturation layer on the windows (master and blues)
> Levels layer on the upper middle part of the ceiling (masked with an oval selection to brighten this area)
> Saturation layer on the paintings (master and reds)
> Vibrance layer on the paintings (for a more even saturation)
> Color balance layer on the paintings (for cooling the colors a bit)
> Curves layer on the floor (enhancing the reflective look)
> Curves layer on some parts of the ceiling (more contrast)
> Vignette effect using a masked fill layer [details]
> Sharpening using the high-pass filter [details]
