London's Houses of Parliament at night

Obviously this is a much-photographed scene, but I couldn't resist during my trip to London in March this year. There were quite a few other photographers along the Thames path, between this point and our hotel near Southwark Bridge, all with tripods! The sensible choice at that time of night, but I hadn't taken mine so had to up the ISO and apply lots of noise reduction in Lightroom. I also rested my camera on the top of the wall to help with sharpness.

Camera/lens settings: ISO 1600, f/5.6, 1/50s,  18mm, hand held.

Office blocks on London's South Bank near Tower Bridge

I took this in March this year on an evening walk along the South Bank. I don't know what these office blocks are, but their lights make great patterns.

Camera/lens settings: ISO 1600, f4.5, 1/80s, 18mm, hand held.

Moonlight in the garden

I took this one on the 1st July this year - the first time I've tried photographing the moon. It was the hottest day we've had in ages, so still warm enough to be sitting in the garden taking experimental photos at 10.30pm! There were some really fine, hazy, little clouds passing in front of the moon, giving it a bit of an eerie effect.

Camera/lens settings: ISO 100, f/22, 3s, 90mm, tripod.

Night-time shot of the Thames path passing beneath Blackfriars rail bridge, London.

I took this one in London in March this year. I love the undersides of the Thames bridges, especially when they're lit up at night. This particular shot is one of my favourites because of the mixture of lines and curves from the 2 bridges (I think that's Waterloo Bridge in the background) and the wall and railings on the path.

I haven't done much night-time photography and have always had poor results whenever I've tried (usually with Auto settings on a compact camera). Some of my London attempts (such as this one) have come out ok, but they're extremely grainy as I had to use a really high ISO to pick up enough detail. I think the only thing I'm doing 'wrong' now is not using a tripod (conscious decision not to be carrying one round London!), but if anyone has any other tips for me I'd be grateful.

Update! - Thanks to my friend Leanne for tipping me off about the Noise Reduction section in Lightroom - I now have a much less grainy version (the one at the bottom - not sure you can actually tell the difference on here, though!).

Camera/lens settings: ISO 1600, f/4.5, 1/60s, 20mm, hand held.
