Where was this? Seems pretty irritated.

Noise will be there in the dark areas. We also get more noise when the image is underexposed and then exposure is increased during post processing.

I remember the group photo that I had taken of our graduating batch in XIMB. I was using a ISO 400 film. The grains were the size of golf balls. No idea whether Bibhav, Ketaki, Sharad and other members from XIM have noticed it. Considering that it was only 12 years back, the technology has evolved a lot.
