WOW! Hobbyists building mechanical TV systems! (mechanical scan, but modern electronics)
The Experimental TV Society - lots of history, info -this organization survived only a few years. The First Annual Meeting was on 11 August 2001, 2nd in August 2002. Unfortunately attendance dropped after only two years, and Peter Yanczer, who formed the society, could no longer support it. Peter passed away on March 16, 2014. His pages have been transferred to a new site:
http://www.televisionexperimenters.com/ (06 Dec 2017)
and there is more info about him at the Early Televison Foundation site
http://www.earlytelevision.org/Yanczer/yanczer_index.html (06 Dec 2017)
Besides all his construction activity on his own gear, Peter contributed to the restoration of antique receivers at the ETF.

Translation (go to the site to see the images):
The pantélégraphe of Caselli is an autographic telegraph able to transmit a faithful reproduction
of a handwritten letter, a drawing, a plan or of a portrait.
Pantélégraphes de Caselli exposed to the Museum 1861
The pantélégraphe of Caselli used on the line from Paris in Lyon and Marseilles was able to transmit
a manuscript of 26 cm X 11 cm in 20 minutes.
This apparatus is made up:
of two series of copper plates.
stylets allowing the inscription of the messages.
Plates of the pantélégraphe of Caselli exposed to the Museum
of a 2 meters length heavy pendulum, connected via rods to the stylets.
Pendulum with electromagnets of the télélégraphe exposed to the Museum
Principle of operation:
On the copper plate of the starting station was posed a metallized paper sheet (silver plated blank paper sheet).
The message was written with an insulating fatty ink .
On the copper plate of the station of arrival was posed potassium cyanide an impregnated paper sheet which broke
up into Prussian blue under the action of an electrical current and thus impressed the sheet.
1. The message was written as a preliminary on the paper sheet metallized and posed on the copper plate.
2. The employee sent an aural signal to the receiver and they started their respective pendulum.
Contactor with two positions " to receive - to transmit "
3. When the pendulum carries out a complete oscillation, the stylet traverses the dispatch over all its width.
When the stylet met a conducting part (metallized paper), the current delivered by the pile circulated only
in the circuit of the transmitter (the resistance of the wire of line being much higher).
When the stylet met a nonconducting part (fatty ink), the power delivered by the pile did not circulate any more
in the internal circuit of the transmitter and could be on in the wire of line. Ink played the role to some extent
of a double switch allowing the passage of the current in two different circuits (internal circuit and external
circuit).
Pantélégraphe with pile and wire of line
4. The message was transmitted by the wire of line to the receiver.
5. On the plate of the receiver the potassium cyanide was broken up by the electrical current intermittant and
the message appeared.

Mexican field-sequential color patent: http://www.mexconnect.com/mex_/travel/tonysarticles/tbdid1003.html
(06 Dec 2017)
Did You Know That....the world's first patent for a color TV was granted to a Mexican inventor?
Guillermo González Camarena was just 23 years old in 1940 when he obtained US Patent No. 2,296,022 protecting
his invention of a "Trichromatic" system for color television transmissions.
The method is sometimes referred to as a "field sequential" system. Basically, a motor-driven disk, consisting
of three segments in the primary colors - red, blue and green - rotates behind the camera lens. The resulting film
is monochromatic (black and white). If it is replayed fast enough through an identical disk, precisely synchronized
with the original filming, then each separate single-color "filtered view" is retained by the eye long
enough to complete a full-color image.
The system became the first color TV system to be approved by the U.S. Federal Communications Commission, and in
1950 was accepted as the "standard" system. Its major disadvantage was that the signals used to transmit
the images did not allow a good picture to be obtained on any TV that was only capable of displaying black-and-white
images. [more on the web site]

A passage:
THURSDAY, JUNE 24, 2004 CONSUMER ELECTRONICS DAILY — 9
BMC Industries, once among the world’s leading suppliers of aperture masks for CRT-based TVs and PC monitors, filed
for bankruptcy protection Wed. and said it had reached an agreement to sell its Vision-Ease eyeglass lens business
to I.E.A.P.X, a Tex.-based limited partnership. BMC, which filed for bankruptcy inMinn., said Vision-Ease will
“continue operating without interruption.” Details of the filing, including a list of creditors, weren’t available
at our deadline. The company said in late Dec. that it would close its aperture mask operations, including a plant
in Cortland, N.Y., by mid-2004. BMC, once a major suppliers of aperture masks for direct-view TVs up to 36",
suffered as sales of flat-panel TVs increased. It expanded production in the mid-1990s to include aperture masks
for PC monitors and opened a plant in Mullheim, Germany. BMC also sustained a major blow in 1999 when the International
Trade Commission rejected its complaint that sought to have antidumping duties imposed on aperture masks exported
by Japanese and Korean manufacturers. BMC had argued that the U.S. industry producing aperture masks was being
“materially injured” by “less than fair market value” imports. BMC’s production had declined since the mid-1990s
and it closed 3 lines and laid off 489 employees at the Cortland plant in 1998.

History of ac power (mains) frequency, which determined the 60 Hz NTSC / 50 Hz PAL scan
rates:
In the U.S., Westinghouse used 60 Hz for flicker-free incandescent lighting, while a much lower frequency (often
25 Hz, but sometimes lower) was used for powering large motors. (The motors would operate best on DC, and better
at lower frequency AC than at 60 Hz.) Also, synchronous converters for other frequencieswere developed to operate
best with 60 Hz on one side. In Germany, AEG had a virtual monopoly, and their choice of 50 Hz spread widely, except
in Britain, which didn't adopt 50 Hz uniformaly until after WWII.
(For more information on ac standards, see
Hughes, Thomas P.,
"Networks of Power: Electrification in Western Society, 1880-1930",
Johns Hopkins University Press, Baltimore, USA, 1993)

Disposable camera exposure (Link no longer available)
Quoting the site: "According to Fuji consumer information all their cameras have single element glass lenses.
The Quick Snap Flash has 27 exposures of Superia X-TRA 800 speed film. The lens is an f10 with a focal length of
32 mm. The shutter speed is 1/125th of a second."
"Kodak says their best is the Max HQ Flash. It comes with an f10 30mm Ektanar plastic double element lens.
The shutter speed is also 1/125th. There are 27 exposures of 800 speed High Definition film. The recommended distances
are from 3 feet to infinity outdoors or up to 15 feet inside with flash."
This means that, in full sunlight, disposable cameras overexpose the nominal film rating by 16 times, or four
stops. The great latitude of color negative film allows this to be recovered in the printing process. This allows
for photos to be made in the shade or under cloudy conditions, and extends the range of the small strobe flash
in these cameras.

You think you’ve got it tough getting reasonable color reproduction of a photograph on your ink jet printer? Think about the print process industry, where the clients want to know and control how it will look in low-quality newsprint without firing up the huge presses to test each advertisement. This is the problem of color management –getting the desired color when the process is capable of it, or predicting the result when it isn’t. (And in many cases, like your home printer, predetermining or automatically deciding what distortions give the most pleasing result when exact reproduction isn’t possible.)

AIM - Accurate Image Manipulation for Desktop Publishing:
The proprietor of this site, Timo Autiokari, has picked an unnecessary fight with Charles Poynton (see his color
FAQ site above), and has a semi-religious attitude toward gamma correction, but has much good stuff. He shows (which
every TV effects generator designer already knows) that operations affecting the spatial frequency response (smoothing
or sharpening) need to be done in the linear domain to maintain local average brightness and avoid excessively
bright highlights. He also has effective demonstrations that the local image background affects the perception
of gray scale uniformity, and thus affects what quantization will be acceptable in a given image. He makes the
valid point that images that are quantized and bit-reduced by JPEG so that they are acceptable for display are
often not acceptable for input to image processing/manipulation. However, he jumps to the conclusion that only
linear quantization is acceptable for input images, and further makes a claim (which most researchers would refute)
that a gamma of 1.25 results in perceptually uniform quantization. His illustration of this is a set of gray scales
on a white background, which of course is really illustrating his valid point on the effect of surround. The quantiziation
may be close to perceptually uniform for this particular image, but his other illustrations show how greatly it
can vary depending on background level. The proper conclusion is stated elsewhere in his site: perceptually uniform
quantization depends on the background brightness. Other research confirms that the response of the eye under average
conditions is close to a cube law, or at least a power greater than 2, so if you must choose one number to be least
likely to show contours on a wide range of material and with the coarsest quantizing, the sRGB choice of 2.2 is
a good one. (The author of this site also implies that sRGB is somehow a sinister plot of equipment manufacturers
to sacrifice all quality for the sake of economy.)
sRGB is related to television gamma practice, which has found in fact that uncorrected CRT gamma is greater than 2.2, giving an overall system gamma of about 1.25. The actual gamma correction curve used in TV cameras includes an offset that results not only in a stretching of blacks but also a clipping of extreme blacks. This, combined with flare light in the display and the usually darker picture surround, gives an overall visual impression of linear gamma and an s-shaped transfer curve that results in pleasant pictures on a CRT display. Of course, this all needs to be undone before applying the image to processing or output to another type of device. However, of all the devices that might be catered to, CRTs are the least troublesome, since their input/output relationship always is characterized by a smooth power law that approximates the requirements of the eye for perceptually uniform quantization ( I am ignoring phosphor highlight saturation, which can occur for projection devices with high current density). Other devices such as printers and LCD displays have much worse linearity and gamut problems, and differ greatly among themselves. The over-all gamma of 1.25 results in some increase of saturation, which compensates for flare light, and also distortion of hues towards the primary colors. The hue shift with an over-all gamma of 1.25 is generally considered small enough to be acceptable for concumer display, but in accurate graphics work it would be desirable to eliminate it, as the author points out with some extreme examples. All that is necessary in processing to avoid the hue shift is to return the over-all system gamma to 1.0. To judge this effect for yourself in normal images, pick a picture with some reasonably saturated color(s) between the primaries and secondaries (e.g. orange or green-yellow or purple), and apply a gamma (mid tone) adjustment using your favorite photo program. You will see a strong effect on the gray-scale rendition, of course, and you will be able to judge the relative importance of the hue shift. If the original image contains skin tones, you of course will want to judge them also.
It would be desirable perhaps to develop a process for adjusting tone rendition that maintained saturation and hue. I haven't tried it, but conceptually, one develops an adjustment layer (pixel-by-pixel value of the adjustment, for those not familiar with PhotoShop) from the luma channel, then applies it multiplicatively to the linear red, green and blue channels equally. The goal is to maintain the ratios of the primaries, while adjusting their level according to the desired tone rendition curve.
There have been many proposals to introduce linear processing in TV systems over the years, mainly as a means of improving the detail contrast in highly saturated colors and reducing color smear. (Note that professional TV cameras do include linear matrixing of the sensor outputs to achieve the correct taking characteristics for the TV primaries - that does not affect this discussion.) The smearing and lack of detail (especially visible on reds) in TV is due to the very low bandwidth of the chroma signals (typically 1/10 of the luma bandwidth in analog composite signals). However, the effect at edges of saturated objects is to roll off the brightness as well as the saturation, giving a plausible effect of an object of nearly constant color with a shaded edge. When a linear domain is used for transmitting the reduced bandwidth chroma signals, the edge can be seen to have a reduced saturation that looks quite unnatural, as though the color had faded towards gray. Linear processing where all signal components have high bandwidth does not suffer from this effect, but then it does not suffer from color smearing either.
Of course, if you can afford the bits, it is better to have linear input to your image process - no argument - but this is a requirement due to the subsequent non-linear processes which enhance the contrast of artifacts, not a direct need for display to the viewer, where quantization in the gamma-corrected domain is preferred.
The site author has taken care to gamma correct the posted images so that they display correctly on the the
typical uncalibrated monitor (which may have a gamma of 2.2 or higher). I believe you can learn a lot from the
illustrations of image quantizing and processing on this site, just be careful to judge for yourself what your
eyes tell you, and make your own decisions about the philosophy.
