Thanks Jane,

This is not an HDR, it's a single exposure using a tripod. ISO is a measure of light sensitivity and it still means what it used to mean, but technology has moved on. Modern DSLR sensors are getting better and better in low-light situations so shooting noise-free at 400 is not unusual.

As for email addresses ... I don't like publishing them because I get enough spam as it is :)

Hope that helps,

Bart.
