...Thanks for the info, Ryan. (Hey miss the League!)<br /><br />Pappy, I remember that too. Hey, do you remember TVs that had to warm up and when shut down always left that little dot of light in the center of the screen? Man, extinct artifacts of technology.Sleestakhttps://www.blogger.com/profile/08512281434803286602noreply@blogger.comtag:blogger.com,1999:blog-14759247.post-32493820233333848452010-02-23T18:52:32.684-08:002010-02-23T18:52:32.684-08:00I remember the dark halo and wondered what it was,...I remember the dark halo and wondered what it was, but TV technology was so bad that even as a kid in 1954 I remember thinking that live TV was total cheese. Lighting, sets, all pretty bad...<br /><br />I also remember something that has disappeared with tube TVs and the scan lines across the screen: moire patterns caused by men's suits or ties with pin stripes. They'd squiggle, and if I was watching my local Ted Baxter newscaster and his brand new Father's Day tie was squiggling I was always more interested in that than the news.Pappyhttps://www.blogger.com/profile/01977289662431694607noreply@blogger.comtag:blogger.com,1999:blog-14759247.post-50264051565465352992010-02-23T18:27:52.879-08:002010-02-23T18:27:52.879-08:00I used to work in video, but well after the black ...I used to work in video, but well after the black and white era. <br /><br />I worked with a mix of tube, analog and digital technology at that crux in the late 90's where things were changing incredibly fast. The effect you're discussing isn't familiar to me (as its b&w), but it does sound like the limitations of early video in the tube cameras I used. Once tubes disappeared, the "latitude" of video was improved (but not perfect). A lot of effort goes into finding that mid range of lighting, which is why they tend to flatten news sets, etc... with lots and lots of light. <br /><br />Anyway, you can see some odd "artifacting" on tube cameras.The Leaguehttps://www.blogger.com/profile/04836241071795980225noreply@blogger.comtag:blogger.com,1999:blog-14759247.post-67329840941181003462010-02-23T13:33:53.064-08:002010-02-23T13:33:53.064-08:00That' good to know.

Looks like the effect was actually on purpose to an extent in order to make a blurred image appear crisper, something that would be desirable because of the low resolution televisions of the past. But it was easily overwhelmed.Sleestakhttps://www.blogger.com/profile/08512281434803286602noreply@blogger.comtag:blogger.com,1999:blog-14759247.post-32971079440015026122010-02-23T11:50:39.270-08:002010-02-23T11:50:39.270-08:00It looks like the term for the dark halo is.. &quo...It looks like the term for the dark halo is..

I want to say it happened at some point in the last Hartnell serial.Falconerhttp://falconsgyre.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-14759247.post-61055389191178993492010-02-22T10:03:25.591-08:002010-02-22T10:03:25.591-08:00Holy cow!
