Ganesh,
Those are profound thoughts.
" partial knowledge of things "
but only as regards the laws of our own nature taken separately
These lines make a lot of sense.
Raj,
Yes, A series or collection of images helps us to share thoughts in a more efficient way. Many times a single image will not be enough to elucidate what we are trying to say.
However, I also feel, in the quest to make a point we snatch the very essence of photography in a series i.e. freezing a moment. A photograph is different from a painting or a piece of literature by its ability to be spontaneous and capture a given moment without having an opinion. A photograph may be political, conservation-related, etc, but at the heart, it is just a spontaneous reaction of the photographer to a scene. A collection is a compilation of opinions of the photographer.
For a long time, I thought working on a theme is better than capturing random themes/ moments. But off late I have started feeling otherwise. being able to be at the scene is what a photographer needs most.
Just a few more thoughts to add your observations. Hope I am making some sense.
