Madhav, it is a fairly large crop 4332x2115 (~52Meg) from 36M Nikon D810. The actual file is much smoother which I kind of didn't like
Coming to the border, have you heard of 'photo distressing' ? During good old days for creative and artistic reasons a few photographers use to scratch negatives/slides/prints and use other techniques to render their inner visions on the final prints (search google for 'negative/print distressing'). Some folks used tea water to distress prints. In US one can buy distressing inks to distress photographs.
Here I kept the border distressed a bit so that it goes well with the 'remains' mood. I had these kinds of borders for my images earlier too (check
this link). Nik's s/w made those hard manual job much easier in s/w now! However, it also brings in some amount of predictability to such borders. In the link above I decided to 'manually tear' those edges so that all does not look alike.
