Hi, Dale,

I don't think it's anything warped.  I'd agree that there is a certain  
"gosh" factor to TK-41 stuff I've seen from network shows.

David and long-time Sr. video engineer/camera collector Chuck Pharis  
could comment more from the experience of working with and viewing the  
output of the cameras directly.

I'd think it's partly the 3" IO's.

One could liken the larger tubes in the TK-41 to medium format (120,  
220, 6x6mm) still film compared to smaller 35mm still film... and its  
electronic counterparts would be the 1.25", 1" and 2/3" Vidicons,  
Plumbicons and Saticons in later cameras.

Continuing that analogy, film emulsions have different reactions to  
light and color.  I think part of the magic might be how the tubes'  
reacted to light in an electrophotochemical way. The tube design and  
photosensitive material... and size contribute to the "look."

Other more easily observed factors are the care with which the cameras  
were set up by NBC engineers, coupled with the lighting and staging in  
front of the camera.

It would be interesting to compare how local stations TK-41 video  
looked compared to the networks' TK-41 pictures.

As for the algorithm:  TK-41 look applied to some HD material?  I'd  
think there'd be a "halo" button in the software controls and a slider  
to address halo intensity and width.
