Lytro-chamber: about Steve Jobss plans according to the photo invention again and technologies of shooting of a light field
Update a year later: we look the Lytro chamber video review.
Book «Inside Apple: How America’s Most Admired and Secretive Company Really Works», written by the senior editor of the Fortune magazine, Adam Lashinski (Adam Lashinsky), opened, maybe, not less riddles of the popular company, than Steve Jobs’s biography. It appeared «to invent one of such riddles again desire of a soosnovatel of Apple» the photo. And development prestigious now and the Lytro company popular in certain circles was one of components of the courageous plan. It is a question about plenoptichesky to a photo or shooting of a light field which at present looks something from fantasy area, but already in the current year will be reality.
As it became clear from Adam Lashinski, Steve Jobs’s book met the executive director of Lytro, Rehn Anghie (Ren Ng), and discussed with it technology plenoptichesky a photo, also possibility of joint cooperation. As well as last head of Apple, Angie — is very unusual and courageous person. It predetermined the dissertation to other technologies of photographing, and after receiving degree of the doctor of philosophy based the Lytro company and started to realize the researches in a real commercial product which would be financially available though to what wishing. Let’s try understand, what such shooting of a light field and plenoptichesky a photo, whether really it having dug in the field or simply sensation from scratch and why Steve Jobs became interested in Angie’s development?
Small and strange outside the Lytro chamber with great opportunities
If to transfer technology possibilities in 2 words, it will be expression «without focusing», and still — «an instant picture». Exact focusing is a basic component of a qualitative picture, it is possibility to build cool composition, to focus attention on a certain object, to give a photo a certain sensual coloring, well and in principle, without having focused, it is impossible to embody a desirable picture correctly. And how many the cool moments were missed only because is ordinary was mistaken with focusing, did not manage to make it or badly worked the mechanism of automatic focusing. Researches in the field of shooting of a light field solve dely with focusing, at all this on a root.
Traditional cameras, whether it be the abrupt SLR camera, trivial soap tray or the ordinary photomodule in phone, during shooting keep information on color parameters of a certain point on the plane. When shooting a light field data on beams, instead of on points remain. Naturally, in each beam it is possible to allocate a certain point for the planes, so, and to build the accurate image, at all this not one. Actually, in one picture of a light field it is placed much more инфы, than in the traditional JPEG file or even RAW. As a result, using special ways it is possible to be focused on a certain object or to place all shot in focus how the picture is received. At all this the shot is created almost instantly. Remember, how Apple focused attention to speeds of shooting of iPhone 4S? Well, so it is all florets in comparison with shooting of a light field.
The 1st plenoptichesky camera on the basis of Contax 645
In the theory sounds abruptly but how to achieve shooting of a light field in practice? It is quite simple, as the group of students and teachers of Stenfordsky institute in 2005 found out. For this purpose it is necessary to place the so-called plenoptichesky lens consisting from 10-ov of thousand microlenses with different focal length between a lens and a photosensor. Actually seven years ago enthusiasts made model of the plenoptichesky chamber on the basis of the Contax 645 camera. Everything worked, not including that such model of mad means (one only the chamber cost cost some thousand dollars, not to mention a plenoptichesky lens), well and the software for comfortable processing of pictures then was not. Vperva the such was shown by the Adobe company only 5 years later. Here this demonstration:
So, about plenoptichesky a photo we received some representation. What conclusions to the end of 2010 could be made? the 1st — the equipment for shooting of a light field already exists, but it very precious. the 2nd — the software is, though in a rudimentary and experimental condition. And after, among 2011, like a bolt from the blue there is a Lytro technology announcement. At the 1st look the company then did not offer anything new, short of that small detail that she assumed to begin release of a commercial product within a year, at all this «for reasonable and reasonable price» as developers were expressed.
Well, and in October of last year of Lytro presented already ready and operating plenoptichesky camera with the title with the same name in spite of the fact that the public belonged to the first announcement pretty skeptically.

As well as many products of Apple, development of Lytro looks something not from the world of it. Compare "monster" on the basis of Contax 645 and this small accessory of long only about 11 cm! And after all the baby possesses impressing interior even if to exclude «a plenoptichesky cursor», grasping 11 million beams (11 mega-beams) for one picture: 8-fold optical increase, svetosilny optics with constant width of a diaphragm of f/2, 8 or 16 GB built in a flash memory and only two hardware buttons. One is responsible for turning on of the chamber, the 2nd — for instant descent of a lock.
Most that on there is "Apple-stayl" in photographing. Got the smallest steel device and instantly received a picture which can be changed at own discretion later: to choose a certain point of focusing or to place all shot in focus. By the way, it becomes directly on the touch monitor of the camera or in special ON Lytro which first will be available only to OS X, and will appear and in option for Windows a bit later. The result of work of Lytro can be estimated in pictures below (the click on though what part of a photo changes a focusing point, Flash is necessary):
The question price from $400 to $500 it is dependent on volume built in a flash memory, and deliveries of this miracle will begin first the current year. Advanced orders of Lytro accepts already now.
It should be noted that Angie offers on purchase of the technology developed by it or its licensing arrived, but the scientist decided to develop the child without the aid of others. In other words, hardly Jobs was interested about joint release of Lytro chambers. More quickly, conversation during their meeting went about use of technologies of the company in Apple products, to iPhone, for example. Jobs suggested Angie to think over joint cooperation and to tell in the electronic letter on the 3rd things, which companies could make together.
Soosnovatel of Apple left, but its business lives. Steve Jobs longed «again to invent» textbooks and the company made it together with iBooks 2 and iBooks Author announcement. He dreamed in a root to change a TV set — it waits for us in near year, and competitors already worry. The modern world of amateur photographing too is at the crossroads and, seemingly, last CEO prepared the base to make it absolutely another. [9 To 5 Mac] [Lytro]
