Here are a couple of shots from my recent trip to Prague taken in the Old Town Square. This first shot was a normal shot: ISO3200 f5.6 1/25 18mm. NR was applied in LR - 25 Luminance, 25 Colour. 110130-00511 by ...olli..., on Flickr This second shot was taken using the camera's hand held twilight mode: ISO1600 f3.5 1/30 18mm. No NR applied. 110130-00516 by ...olli..., on Flickr If I had shot the first one at ISO1600 and f3.5 I think I could have got close to the same result in LR. That said, using the HHT mode does save work in LR and it does produce a very clean image particularly in the dark sky.
