Time-lapse movies are really a fun way to explore many of the slower events of nature.
Events that happen before our eyes, such as the opening and closing of flowers,
various tropic movements of plants, movement of shadows of stationary structures,
and cloud formation and disintegration, are ideal for time-lapse photography.
Normally we know these events to possess inherent motion, but their time-scales
are too long to register them as dynamic. Only by compressing the time-scale we can
see the beauty of their fascinating motion intricacies. When we look at the
time-lapse movies, these apparently static things magically spring into life.
An inner working of nature, so far obstructed from our normal senses,
opens up in front of us. Below, I present a few time-lapse movies that
I recently created. This is my first attempt of entry into this mesmerizing world.
Have you ever thought how a creeper locates a support in the vicinity and decides to climb up. I used to think that due to wind or some other disturbance the plant happens to fall on the support and once it "feels" the support it tries to grab it. Not so! Plants are far more intelligent than that. They didn't leave such a vital piece of their survival to the pure chance of wind or disturbance. Instead, they deliberately and actively search for a support, which I first came to know from the rich website Plants in Motion of Roger P. Hangarter. To locate a support the vines engage in a fascinating circular movement. When the vine touches a solid support, it continues with a similar motion, but this time it starts pivoting around the support. This causes the wrapping around the support. At the same time the natural growth of the plant causes it to climb up. As a mechanical engineer I am amazed by this motion and think of all the mechanical problems the plant needs to solve in order to properly hold on to a support and grow. However, in the end, the plant seems to have solved an apparently complex job with an ingenuous and elegant strategy, which is very simple. Motions such as this can be captured and studied using time lapse photography. I have recorded a few such motions, please scroll down. Equipments and technique: In time-lapse photography we take a large number of photos of our object in equal succession. The photos are finally chained sequentially and played fast to create the semblance of a movie. I use a Nikon D70 digital single-lens reflex (SLR) camera and Nikon Camera Control Pro software. I place the camera on a tripod, and a laptop running the Camera Control Pro is connected to the camera through USB. In the software I can select the number of photos to take, the time interval between each photo. Each photo is stored in the laptop. After all photos are taken, I use Quicktime Pro software to chain them to create the movies. In QuickTime I use Open Image Sequence (under File menu) for this purpose. Generally the resulting files are large and not so suitable for web. Fortunately QuickTime has another option "Export to Web" to reduce these large movies into web-suitable smaller files. Great website on this topic: Plants-In-Motion. To view the videos you will need QuickTime software which you can download for free from Apple Website: QuickTime Download |

Description :
To create a better uncluttered background I have attached a black chart paper
to a cardboard. In OfficeDepot similar boards with styrofoam back are also
available. They are nicer but lot more expensive. This black background makes
the movies more dramatic.
I have more new ideas for time lapse movies. I will do some more experiments and will post additional movies. |

Description :
I am happy to report that the Morning Glory plant proves to be very
suitable for time-lapse photo experimentation. The plant produces many flowers each day.
The complete life cycle of one flower lasts exactly one day. A flower fully opens up
in the early morning, lasts the entire day, folds itself up neatly at the end of the day,
never to wake up again. A short but quite and contended life-span.
If we cut the flower-bearing slender part of a plant and
dip it in water, the plant will do fine for a long time, definitely longer
than the duration of the flower. This gives predictability and ample opportunity
critical for the preparation of a photographing session. What's more, if you screw up
once, you can restart next day.
The two movies below show the beautiful Nastic Movements of morning glory vines. In the next few days and weeks I plan to explore the folding and opening of flowers. |

Description of the following two movies:
1. The movie shows the effect watering a dried chick-pea seed.
The chick-pea is swelling up gradually.

Description of the following seven movies:
1. The movie
shows the effect of re-watering a water deprived kidney bean plant. The plant
is slowly
returning to normal life over a span of about 10 hours. |
