Suggestions please to get the best night time landscape photos with a Canon t2i (550d) camera with Efs 10-18mm f4.5 - 5.6 wide angle lens and also the 18 -55mm kit lens. Should I remove the circular polarising filters or not, to allow extra light ? Trying to travel light but suspect tripod will be essential. Have seen some spectacular light shows and illuminations I'd love to capture. Can't afford faster lens so will have to do the best with what I have. Thank you in advance.

Shoot in the blue hour, just after sunset - as dark blue/purple skies may be much better than "booring black"
Remove any unwanted filters (to reduce flare) and use a lens hood (to possibly help in reducing flare).
A tripod will be necessity if you do not want to shoot at very high ISO values. A remote release also helps.
You will need to focus manually if the camera has trouble focussing.
Know how to read a histogram.
Shoot RAW as this will give your more control when post processing.

For starters, with these type of shots., I usually set my camera up in manual exposure mode
I think "100" to get me in the ball park, and take it from there. That is 10 seconds @ F10 (or F11) @ ISO 100.

Looking forward to seeing your results.

Haven't been in a few decades, and the high-rises are legion. But, take the elevator up Raffles Tower for the harbor view.

I am not sure what type of landscape photos you are wanting to capture, but you do not need a fast lens for that. As for the circular polarizing filter I would say in general no. You can control the exposure with the aperture, shutter speed and ISO. You will be definitely need a tripod in low light. If you are shooting in low light or sunset or sunrise, the lens you have should do fine.

A polarizer sucks up several stops of light - you most definitely do not want that unless you are using a tripod and going for the long exposure effect.

For the kind of photography you anticipate doing you really need a tripod. If you can't take a tripod, take a large bean-bag which can be put on a short wall, a car hood, etc., and use a cable release or the self-timer sequence to take the photo. There is so much to shoot in the daytime in Singapore as well! And you can probably get some good night-time existing-light shots of the Satay vendors and the market - just use manual exposure with auto ISO, and set your aperture and shutter speed at reasonable levels like 1/100 and f9. Have fun!

Thanks everyone for the good advice. Fingers crossed the weather stays fine and I'm sure we will get some good results.
And if the winning numbers come up on lotto I could visit the camera shops in Singapore as well.
