These are a couple of shots from inside the Cathedral Notre Dame in Quebec City, which is the head of the Catholic Church across all of Canada. You can read some of the Cathedral’s history here on wikipedia
It is a very unassuming building from the outside, but the inside is quite spectacular. We ended up visiting here a couple of times. We happened by it ourselves whilst wandering the streets, and the following day we did a guided walking tour which also stopped in at the Cathedral. Take note of the lovely sky painted on the ceiling. It was very overcast and rainy both times we were inside so it was good to see a little blue sky somewhere.
Both shots here were done handheld with my Pentax K200D and Sigma 10-20mm, at ISO1600 (highest my old body goes!) and are 3 exposure HDR’s taken at +/- 2.0 EV. The noise reduction in Photomatix, which I used for blending, seems to have done a great job on the noise. The noise is still quite noticeable in the full size images though. I used Tone Mapping with the Enhancer method in both cases to generate the final image.
