How exactly do you get a screen shot from a 32 line mechanical televisor?
I had a few attempts to photograph some of the 1960's Dr Who footage I have converted to 32 lines and played via the 32 line Televisor.
The picture on the Televisor is very good indeed with pretty good definition, but the best picture I can get from the set is as below. Any suggestion on how to get a decent screen shot? It must be possible as people did take screen shots from Televisors in the 20's and 30's. I've tried close ups and distant shots, say 12-18" away, but no success. Any suggestions? Peter. |

You need a time of 1 frame (maybe 2) and a high light setting on the camera. And of course a dark room!
And patience!!!!! Cheers, Steve P

Re: How exactly do you get a screen shot from a 32 line mechanical televisor?
Hi,
For a start, you need a camera where you can manually control shutter speed, aperture and focus. Digital cameras seem to be over-sensitive at the red end of the spectrum; you'll probably have to deliberately under-expose to compensate. I had enough hassle trying to photograph a red Hacker RP30, they're more burgundy than anything but my camera (Olympus C-750) thinks they're bright Ferrari red! I'm getting better at photographing off-screen telelevision pictures from regular CRT sets, running the camera in "fully manual" mode helps a lot. There's definitely a knack to it. At least with a digital camera you can experiment with loads of different settings without running off rolls and rolls of film and all that tedious waiting around for development. Financial constraints prevent me buying one of the televisors right now (I definitely want one) otherwise I'd experiment with my camera. Regards, Kat |

Thought I'd try for some photos because I had taken some successfully before, off my own big home-built televisor (though using an old now-broken digital camera) but I find the little televisor has now gone wrong, neither displaying its own test card nor any plugged-in input! All I get is what looks like hum, but at least it will lock to it...
Steve

Hello,
I have got the best results with the Canon Powershot A70: http://bs.cyty.com/menschen/e-etzold...eVersuche2.JPG http://bs.cyty.com/menschen/e-etzold...isk_front3.JPG http://bs.cyty.com/menschen/e-etzold...isk_front2.JPG http://bs.cyty.com/menschen/e-etzold..._light_pic.JPG Videos, recorded with the Canon Powershot A70: http://www.youtube.com/watch?v=9DFcYRxFdTI http://www.youtube.com/watch?v=2dmY43KeBuE http://www.youtube.com/watch?v=osF5gg6RKL4 All photos and videos are taken in the "Auto" mode, not in manual mode. Before I got the Powershot, I have tested several digital cameras. But this was the best for my purposes. Kind regards Eckhard |

Impressive pictures Eckhard! Particularly so because they are mainly of subtle-contrast faces rather than test patterns.
I've now managed to take a photo from the little 'popular' televisor (well down the page) HERE. Steve

That's an impresive picture Steve, glad you got the Televisor running again! What settings did you use to get this picture?
