2024 Superb Owl on CTC-5
 
All at 1/15 second, so motion could be a problem. Also forgot to eliminate room lights on some.

I was looking for owls until it finally clicked.

Super what?

Bowel...

Apparently a lot of us used to watch that crap.

I never cared for sports, and it's been a few years since I could bring myself to watch it for the commercials.

I've had an extreme dislike of football since childhood, (long story.) and by extension, the stupor bowl, but not to swim against the tide, I will say that the Chiefs sure did have a “Swift” win! :p

Superb! :thmbsp:

Great looking 5!

Never mind the game there’s nothing like those round color tubes they really are easy on the eyes rather then rectangular. Being spherical those tubes match eyes.

Each have their own advantages and disadvantages, the roundies had a unique and nostalgic look to them, but in order to get a full picture, you had to lop off the top and bottom of the screen.

Rectangle ones did not have this issue, but are harder to set up, converge due to the corners/ pincushion effect, and some did not seem to be as robust as the round ones, but on the other hand the WERE larger!

Very cool pictures, thank you for posting them!

I had all of my TV sets for the Owl shut off and put away again within five minutes of the game's end. I wanted to forget it as quickly as possible. But, your excellent pictures here made it all OK again. (-:

+1 for the cool pictures!

Other thing crosses my mind, besides the round vs rectangular debate...

BTW, this RCA ad makes some sense, and I may also add... color also makes the brightness sensation (also is contrast related). At least to my particular senses, B&W TV or scenes needs to have more "lumens" (luminosity) to transmit same brightness sensation than color scene transmits...

Perhaps very obvious for people studiyng video or film science (human sensory perceptions), but is cool to watch for itself

But sometimes I wonder if the weight of each primary color for the B&W matrix didn't varies between each individual...

The things you speculate about the psychophysics of color are true.
Highly saturated colors appear brighter than a gray of the same luminance.
Monochrome images require more contrast than color to give the same impression of discrimination between objects.
People with normal color discrimination do vary in their sensitivity to the primary light sources, both for apparent brightness and for the ratios of primaries needed to match an intermediate wavelength.

In addition, because of the gamma of the picture tube and corresponding gamma correction in the camera, the reproduced luminance of saturated colors viewed on a monochrome picture is reduced.
For example, a full amplitude 100% saturated red has Y signal = 0.3, but the monochrome image has luminance of 0.3 ^ (CRT gamma). CRT gamma may be around 2.6, so the monochrome image luminance for this color is only
R=G=B=0.3^2.6 = 0.043, so visual luminance = 0.043. But when you add the color signals, the CRT puts out R=100% (G and B = zero), which has the correct visual luminance of 0.3.

Interesting!

BTW, the B pure signal, having low ratio to Y, is basically crushed to black visually. Is very noticeable in video games.
