Thanks neelu! interesting comment ...
i dont know what a digital sketch is, so i cannot address that point, but i will tell you what i did:
in my film days we called it pushing film heavily ... i have stopped down 3-4 stops on this one, because light was so low and at full zoom, even lower. i wanted to freeze the mouth action. i had focused on the open mouth of the dhole with a full aperture, so the rest has gone slightly fuzzy. and in processing, i "pushed film." so the grainy movement is all from the action and the pushing.
glad that the "effect" was achieved
we should discuss what a digital sketch is, sometime - would like to see what you mean.
best,
A
