From tomorrow till 2 nd Jan I will be away from concrete jungles. No access to blog/mail till 2nd Jan!!
Seasons greetings to all !

Nature Lyrics is a canvas to share my visions and views on nature photography.
When I made this image I had to spend a few hours in planning, waiting for this Tailed Jay butterflies to show up on the flower and thinking about right shutter speed, background to use etc. Happy to know this is one of the winning entries in the 2007 National Wildlife Photo Contest.

May their tribe increase...
Back to seeing, vutlure and its habitat offers some fantastic opportunities. Couple of images above are some attempts at seeing differently and also portraying its habitat. The below image of rock and the vulture was a non-trivial composition for me. While tracking the bird in the view finder, I found this arrangement very interesting.
**UPDATED on 11 Nov 07 ** Made this image below today at Ramanagar..
More images from the trip are at my home Nature Lyrics.

We need to spot them when they are flying - otherwise they are some fallen dead leaves !!
Here is another example of an image of stick case moth caterpillar (thanks to Sindu Ramachandran again to help me id this)
During my pre-university days I did read about Darvin's theory on evolution but at that time my focus was getting better marks than appreciating and understanding theory. Though I understood it then, I did not appreciate it. Now I can appreciate it !
I have been visiting rocky mountains in places like Ramnagar and Savanadurga. Close inspection of these rocks reveals an eco-system which has beautiful adapted to those rocks to survive. I am sure this has happened over millions of years. Look at this image of grasshopper above - what a camouflage ! How did grasshopper develop those colors and patterns of rocks ? Darvin's theory on mutation and natural selection can beautifully explain this. Mutations of genes causes changes in characteristics which may be heritable. This results in a new offspring with different characteristics. Success of this offspring in passing on its gene to the next generation is governed by natural selection - survival of the fittest. So my guess is over millions of years mutations caused changes in appearance of these grasshoppers - those inheritable characteristics which resembled patterns on rocks got passed on to offsprings which then had better survival rate. This continued and today we have a grasshopper which just can't be found when sitting on these rocks ! Nature has found a global optimum !! Here is another image from Ramnagar -
Though not as camouflaged as the grasshopper my feeling is in a few thousand years this too can't be spotted on the rocks. Here is one more from Savanadurga -
Interestingly nature is solving an optimization problem of arriving at life forms which can survive in its habitat. Scientists took this clue and arrived at an optimization technique based on this principle to solve real life optimization problems. This is known as Genetic Algorithms(GA). It is observed that GA has a tendency to settle down at a local optimum. My feeling is nature can't tolerate local optimum (look at the grasshopper!). If this assumption is true then GA is an inferior imitation of what nature does. I think nature knows best about how to cause crossovers and mutations which eventually results in global optimum. As we speak nature is working on finding a global optimum for we humans - going by current trends in all probability it may be our extinction...

Light is essence of life so is it for photography. I had to make a quick trip to Mysore on Thursday. Way back spent an hour or two at Ranganathittu Bird Sanctuary - made this image there. I had an opportunity to make this same image from the other side (front lit) but decided to spend my time and energy perfecting this image. Good thing is dragon flies return to the same perch often and stay there for quite long time. I had time to try different flash out put levels. For this image use a very little fill flash using built-in flash of my Nikon D200. Click on the image to see larger, better defined version.
Macro/closeup photography is a different challenge compared to wildlife and bird photography. The latter needs quick response make meaningful image. While macro photography needs enormous patience. Our subject stays more or less there but getting the right depth-of-field and composition is quite time consuming. We need to carefully visualize and execute. Normally I have to spend quite a lot of time to make an image. When done properly we may end with a very satisfying image.
