So, thanks folks for all your guesses, which either made itself to the 'comments' section or into your minds silently! :)
So as most of you have guessed, as water droplets, or mist or drizzles or whatever you have imagined, it is only partly correct! These images were that of the condensed steam which will remain in the underside of a steel plate which we all normally use to keep on the hot vessels such as for hot milk or for hot curry, in kitchen! :)
Everyday, just before starting to office my mother gives me hot 'kashaya' from a hot steel vessel and before pouring the kashaya into the cup she always used to keep the steel plate which was covering it, in front of me and then pour the kashaya into the cup. I always got attracted towards the pattern of the condensed steam but no luck with time to shoot as I was already late to my bus...well almost always! ;)
So...as said earlier, one Saturday finally I got the chance and mood to capture this wonderful patterns using some of my lenses. Some images that you have seen are made from macro lenses and some from normal 50mm lens and some from the kit lens - 18-135mm (all with or without extension tubes).
There are patterns all around us. Seeing them and moreover identifying them in the busy crowd amidst our ever busy life gives so much of pleasure. Once we start 'seeing' these patterns the world around us magically transforms into altogether a different place...try it....to believe it!
Note: In the last image, the lines on the water surface is in fact the reflection of window pane, beside which the plate was kept!
