sams9s,
As per your request in your previous post, I am trying to attach a few low light /high iso pictures I have readily available in my laptop. Please note that these are almost unedited pictures and certainly not all of them are high quality (just converted from raw to jpgs with serious quality cutting to be able to upload, 25 MB to a few hundred KB).
I am a bit embarrassed to show these mediocre to poor photos. I have a few better ones, but they are in our desktop and would need a bit of work now to upload.
Here they go:

Camp Noel resort 40 km from Munnar in the evening. Aperture priority. Shutterspeed=1/4, f/4.0, ISO=3200. It is taken hand-held.
