lets see...
Nanotechnology - has something to do with manipulations at the molecular level to achieve a specific goal to meet specialized needs unique to miniature environments.
35 mm film - one or more layer of homogeneous emulsion layers composed of dyes that irreversibly change when exposed to light photons. The dyes are sets of organic chemical molecules refined by decades of global R&D in advanced organic chemistry. Each dye is designed for a specific roll. A large amount of information about light photons must be encoded in a limited amount of space. By the way, it turns out one of the classic monographs on 35 mm format photography has miniaturization in it's title: "35 MM Photo Technique, Miniature Camera Practice" H.S. Newcobe, 1945.
Congratulations Kev, you may have the most wickedly satirical post on RFF.
By the way, how do you find the performance of the Kodak sensor? I would love to look at some uncropped wide-angle photos.
Hi Willie,
Thanks again, I'm gratified by your kind interest in my ideas for the imaginary cameras as well as sensor technology...
I'll be very frank here, I did not pass my high school physics exams in the distant past, which sort of explain why I ended up being an apprentice to a commercial photographer...
🙂 I suppose it's why I also take such insane liberties with my technological speculations!
In atonement for my youthful folly, I currently get suscription of Photonic Spectra magazine... And have been following with interest for a recent innovation in the field of photonics; Its known as Quantum Dots, otherwise known as Artificial atoms.
This technology is being applied to the production of highly stable and accurate color dyes for medical and biological imaging research, as well as for high-end color fast LEDs...
Something 'clicked' in my mind then, and ever since, I've often wondered if this form of nanotechnology could someday end up in our DSLR's imaging sensor...
The current problems of both CCD & Cmos sensors is they're both essentially monochromatic, hence in turn requiring CFAs (Color Filter Arrays) which are basically destructive to the integrity of the image quality. They capture photons to create images instead of being like Silver Halide film which reacts to light photons... Aside from the CFA layer on top of the sensor, we need IR filtration, Anti-Aliasing filtration, Microlens arrays, etc. The image is basically 'F..ked' (pardon my French, I'm ethnic Chinese!) before we even record it to digital.
With nanotechnology, the possibilities for an imaging sensor that does not require any prior destructive filtration become possible, most importantly, a true full RGB color spectrum sensor instead of today's 'color-blind' sensors! Sensor self noise is virtually gone, and finally we go back to the same light reactive imaging recording principle of film instead of light capturing with today's sensors...
Is that wicked satire? Hands on my heart, I hope not! For all of our sakes...
Regards,
Kev
