Top Left To Lower Right <<>> Shofar Blasts <<>> What The Camera & The Photographer Each Saw

            My Vision is the world as I see it... It is frequently not as the camera interprets it... Why is that? here is a brief and superficial statement as to a number of the causes of the similarities and differences intended or unintended by the camera's designers... 

There are many events that go on in the life of a photon or quantum of light moving through the camera's optical train. It moves through the many lens elements, bounces off the mirror, and scatters from all internal surfaces and walls. Then it begins  marvelously complex interaction with the many elements of a modern camera sensor that lies more or less in the focal plane of the camera... We have not even mentioned the camera's built in software that attempts to present what each sensor pixel sees in a way that reminds the human eye what it sees when it looks at that scene under the prevailing illumination from all sources and in all directions. The human eye does not have rectangular pixels so that results in artifacts affecting the image too. Images really need to be analyzed in the spatial domain and in the spatial frequency domain. The latter is called Fourier optics.

I haven't even discussed the human eye as a sensor, and its effect on the image. Do two people ever see the same image with all its qualities? Right now, we do not know. However it is possible to envision (Unintended pun) examining images as seen within the brain and comparing those from different people. I have thought about that but have not searched the literature. 

This is way too brief! One can write a book about all this...;)) And indeed books have been written!!

Aside: I do have ideas for improving human hearing as it deteriorates with age and with exposure to too loud sound sources! I now understand why existing hearing aids are so limited in effectiveness.  I do have ideas for improving hearing aids, by orders of magnitude, but I would need a source of funds to investigate these with appropriate equipment and people. First we would need to obtain the needed test equipment. I would have to hire some technicians and rent lab space... I know my friends at ALOHA would all benefit from such improvements.
