Restoring a Vintage Color Television Set


How to Photograph Vintage Color Television



Introduction. As restoration and calibration of my ragtag mutt progresses, it becomes more important to call on past photography experience to share my progress and setbacks.


In another section of this site, I have laid out some of my life as it related to the primary subject: CT-100 restoration. Left out however was experience ‘shooting’ magazine and book covers. Actually, shooting is simply a term for a very complicated process that stresses huge helpings of both artistic and technical talent combined with a big dollop of win- and lose-based experience.


What talent I may or may not have I leave to the evaluation of others. What I can call on is experience gleaned from over two-hundred newsstand magazine and trade book covers. Some of those covers, I have learned with some modicum of pride, are in magazine collections of CT-100 owners. Buried in a shelf overlooking the main floor of the ancient Asbury Park (where I live) library are bound collections of magazines from the ‘70’s with my name, fingerprints, and sweat all over the insides and covers. Well, maybe sweat is too strong a term; it was always too much fun.


A Little Background. A newsstand magazine cover is a point-of-sale advertisement. It says here I am. Look at me. Pick me up. Here’s what’s in me. Reach for your wallet.


To turn casual curiosity into cash-on-the-counter, you need a catchy picture, bold cover lines, and talented people to put it all together. Some would probably be surprised at how much planning detail and time goes into shooting a cover photo. I once came up with an idea to mimic an engineering drawing with its top, front, and side (orthogonal) views. Instead of drawing the subject (a small build-it-yourself gadget), I wanted to photograph the three views, arrange the photos to mimic a blueprint, and hope it sold a magazine. When the cover art director approached the photographer with the scheme, the photographer scratched his head a bit and solved an unusual problem.


Instead of shooting the pictures with his professional 4x5 bellows camera, he rented a 1000-mm lens for his 35-mm camera, put the gadget in one end of his main studio, walked through a hallway to his smaller studio, and set up there. Distance? There were probably between 40 and 50 feet between the gadget and camera. [BTW, it was on the fifth floor of movie mogul Mike Todd’s former mid-Manhattan townhouse.] But I digress.


Why did Lenny the photographer go to all that trouble? Parallax. He knew the bellows camera close to a small rectangular box wouldn’t look exactly, maybe subliminally, right in a photograph that was to depict just two dimensions. What detail. What a lesson for me.


Setup. This is not the subject of this discourse, but before you can expect superior results, you need a superlative picture. Does the picture meet standards of gray scale? Does it have adequate color? How’s the contrast? What is the room illumination like? What is your video source? A cable signal overloading the front end creating impedance issues, swamping the tuner with a 120-channel wideband onslaught, and generally causing swirly things to happen on the screen, is not your first choice. Certainly over-the-air NTSC is not the ubiquitous thing it once was, but it gives me a warm fuzzy. I gotta believe the chief engineer at my local VHF or UHF channel is doing right by FCC technical standards. Whenever possible, I use over the air signals.


Do not photograph your set in a room full of light. Turn off the lights. Pull the blackout shades, or whatever. You must control the room light, and the room must be dark.


Do not use flash. Do not use flash. Do not use flash. You might think this would be obvious, but remember, the television picture tube is creating the light you want to photograph. You are not photographing reflected light. You are photographing incident light. You must expose your film or CCD with light from the glowing phosphor in the CRT.


Sure, I always use the automatic exposure feature in my El Cheapo digital camera. Set up a manual exposure if you wish. But for the automatic exposure shots, it’s best to use a tripod or stabilize your camera against a wall or some fixed object. The camera I use requires a relatively long exposure, which causes two problems: you smear the picture from your movement and the video picture smears easily from video motion. Using a tripod eliminates the first smear; your selection of the video subject helps control the second.


Taking. Take lots of pictures. That shot on the cover of the magazine I started in 1976 is the one winning shot from five rolls of 36-exposure 35-mm film. The setup for that shot took days. Imagine the model, the location, the model’s outfits, the location setup, the actual shooting, and the sifting process to find the one right shot for a magazine cover that says, “Reach for your wallet.” So, take lots of pictures.


Subject: what to shoot? If we begin with color bars, the basic technical test signal, we can develop subject matter that will show off our vintage color television well. The modern color bar test pattern displays three primary colors, two colors developed by mixing primaries, and the absence and presence of primaries, or black and white. Professional bars use the following white-to-black progression:




As an integral element of color, luminance also maintains a white-to-black progression:


 white-grAy6- grAy5- grAy4- grAy3- grAy2- grAy1-black


Color bar position depends upon the luminance level of that color. The color bar pattern is striking in that it contains broad areas of a given color. They are bright, pure, and near saturation, neither pale nor mottled. So, can we show off our prize in the best possible light if we select program material that reflects color bar characteristics? I think so.


One bit of programming that matches those requirements is animation. It has large areas of color. Usually, you can find a couple of frozen frames to expose for maximum sharpness.


If you also want to shoot screen shots with live video, look for sets and shots with large areas of continuous color. Check brightness levels when you change channels. A soap opera shot in HD and transmitted in NTSC appears to have lower overall brightness than, say, my local news team broadcasts. I have no technical evidence to offer, it’s just an observation. One way or the other, you want to show off your vintage tube, and so make the setup part of each new series of exposures.


Finally: If you take a picture and ‘touch it up’ with Photoshop or something, let me know. Better yet, don’t retouch it. If it’s not right as taken, take it again and again till you get it right. I illustrate this little tome with just one shot taken this morning, November 29, 2005 of CT-100 B8000194. It combines animation, live video, and graphic art. It contains examples of all primary colors and shades of others. It contains pure white. It has impact because it has Color Color Color. It contains pure black. It’s an over-the-air NTSC signal. It is in the top tier of hundreds of screen shots. I like it. I trust it inspires you to better it.
