Boats at Night

[_Nik]

I can't really say why this picture came out so noisy.
Although was taken with a P&S cam , I had it on Manual mode, ISO - 100. Had a long exposure (Cant remember shutter speed) but the camera was placed on the Wall so there could not have been any shake.
As I look into it now I don't like the composition but for this I am more concerned on the noise as most of my night pictures are coming out like this

It shouldn't look that noisy at ISO 100. Are you using the highest picture quality setting? How many megapixels was the image? You could also be shaking the camera slightly when you press the shutter, but that wouldn't explain the noise.

Yes, this was on the max size settings. The original image was 4320 * 3240 pixels before I re-sized.

Isn't it because there's two ways of getting digital noise, high ISO and/or long exposure? Maybe if you'd let the ISO go to say 400-800 the exposure time would be much shorter & you'd have reached a best compromise.
Like Krusty says, there seems to be a bit of camera shake too. Maybe use the timer if you can.

Check your image EXIF data to see what settings (ISO, F-stop and shutter) were actually used. Many P&S cameras use an AutoISO feature which could cause this. You could also be getting "noise" through excessive exposure time and although an ISO 100 setting would produce lower noise at faster shutter speeds an image capture of 10-20 seconds would have more noise.

Thanks guys for your inputs. Will try to get a good balance between ISO & Exposure time & check the results.
