That's what Lytro, a technology/camera/picture format/convergence of all is all about.
A very sophisticated matrimony of tech and camera indeed, once the camera out for sale that is.
The theory behinds it is something called Light Field, whatever that is, which will enable you to alter the focus of your digital shot at your disposal. Some other call it plenoptic camera.
Although I don't know what good that is for the professional camera-slingers a.k.a those who can focus their camera alright before they shoot, even under the danger of death, I certainly belief that it will bring much good to me.
As much as I love all products of photography, from digital to ancient black and white; from art to journalistic; from serious to downright silly, I'm not that good at taking picture...or in it as a matter of fact...
The technology and camera is the brainchild of Mr. Ren Ng, a scientist/entrepreneur/a man who can't focus his camera.
Will it be big? Sure! Judging from the greater proportion of people like me, obviously lacking in photography.skills, compared to those who are adept at shooting things with their camera. This one look promising already
Not to mention all that photo-blogging frenzy which will become even frenzier after this product is released for public.
From all the possibilities Lytro can offer, I literally drooling when imagining what impact it will bring to the field of art. If toy cameras and the pictures they produce, as in recent years, have become such fertile soil for art, what will plenoptic cameras as such bring to photography art scenes and exhibitions. Upon my soul I swear that this will bring a whole horde of new artists and new field of digital art too...
So thanks to the Ren Ng's friend's daughter, whom he couldn't focus his camera on, which then gave him the idea of "shoot first, focus later," we get a gift, which probably is the next big thing after digital photography itself.
