Thanks for the nice comments!
Can I ask what type of camera you have.
I used a Nikon D90 with the normal Kit-lens 18-105 mm.
As there was no flash allowed I took most of the pics at 3200 ISO without noise reduction.
Some shots are even taken at 6400 ISO and the D90 did a good job with relative noise free pics.
I can truly recommend it.
Here's a great website.
Take a look at the camera reviews by Gordon Laing from New Zealand and check out
the video tour on the different camera models.

The modern DSLR-cameras are all excellent cameras and you can take great pictures with all of them.
It's more important that you get good lenses and if you want a great performing lens
I can recommend the "Sigma 70mm F2,8 EX DG MAKRO" lens.
If you often shoot in "available-light" and at High ISO, the Nikon D700 and the
Canon EOS 5D Mark II are both excellent performers. But unfortunately they aren't the cheapest cameras.
