the curvature of these new sensors must be such that its radius should have the vertex exactly on the "nodal point".
In such a way that each pixel is equidistant from the nodal point. In this way the focus works much like human eye and all the physical problems (aberration, vignetting, focus at the edges) arising from the progressive increased distance of the pixels of the sensor flat (as like the points of the film) moving from the center toward the edges, are eliminated in one fell swoop!
But there is a problem:the nodal point is not a fixed point. It moves by changing the focal length of the lens. So I wonder, what consequences it will result.
Either manufacturers build the perfect camera lens with "fixed focal length", or they invent variable curvature sensors? I really do not know

Giuseppe Fallica: Leonardo da Vinci, many centuries ago, had realized that the mechanics can copy from nature. And if the eye retina is curved, there is a reason...

No problem and no controversy. We are not talking about "art" (the quality of which is not measurable), but about mechanical tools. If the idea works or do not work, the result will be verified and measured with mathematical accuracy. :-)

I regret the times of the glorious Hasselbad 500 with the Planar 80mm. This new object has a look that wants to be original, but that finally is only baroque and not sober. Inside, I'm afraid, it's a blend of third-party tecnology (Sony, first of all) which is likely not to be able to run to the fast pace that the market dictates. In other words, Sony already has better things in the drawer, directly with its own brand.

Giuseppe Fallica: Improving photographs working on levels, curves, contrast, saturation, filters, lights, shadows, gamma, as well as using HDR techniques, photo stacking, etc.., is deontologically appreciable, because the final result, however, isn't a fake: only a picture improved.
Techniques such as the one here illustrated, however, leave me puzzled because goes beyond the Photography and entering the creative montage. Which often has a great artistic value.
But that's not Photography.

P.S.
Jean, It's obvious that my comments were related to the purposes of the technique, not to the the "technique itself". Your tutorial is a masterpiece and I will be the first to use it!

And I do not mean just photojournalism social or war reportages. Even the landscape photos are discarded without hesitation by newspapers such as National Geographic, if counterfeit beyond what is a simple calibration.
The case of the legendary Robert Doisneau photo "Kiss by the Hotel de Ville" is completely different. We discuss it if the kissing couple is casually on site, or it's a couple in a pose. But even in the latter case, technically, no question of a montage.
Infact, one thing is to create a scene or a situation. Another thing is to remove people with rubber ...

Do not get me wrong.
I assumed that creative manipulation has a great artistic value, often even more than in documentary photography.
But it's another thing.
It's therefore necessary to understand what we are talking about: creativity or photojournalism?
In the first case it's ethically permissible to use any tool. No limit.
In the second case, It's ethically allowed the use of calibration tools, but not "manipulation".
It was discovered that some photographers, trying to emphasize the famous tsunami a few years ago, have created photomontages using pieces of Niagara Falls.
This is unethical.
The newspapers, now more than ever, in the digital age, they are very strict in this respect.

Giuseppe Fallica: there is a big misunderstanding.
There are two ways to use the hdr technique, totally different.
The first is a technique simply aimed at expanding the range of tones in the presence of wide light variation.
This technique generates classic normal images, and the skill of the photographer becomes even more great if the observers appreciate the result without needing to understand that it is used the HDR technique.
else, completely different, is the HDR tecnique used to generate surreal or hyperreal images.
do not confuse the two.

I mean: the first way of using the HDR technique is - in concrete - a simple adjustment, calibration, of images (therefore, in my opinion, it can be used in photojournalism).
The second is a technique of "manipulation", reality distortion, designed to create photo art, surreal or hyperreal that cannot (must not) be used in photojournalism. Of course.

The utility of the "mirror" was exclusively based on the existence of the film as a recording support.
Today, as the media is a "senso"r, which allows viewing of real shot (through the viewfinder or the LCD screen), SLR architecture does not make sense anymore: it's just a survival of the past that, sooner or later, will disappear. The philosophy of the Sony NEX-/ or Samsung NV200, marks the way of the professional cameras of the future.
