The Curse of the Double Exposure

 Back in the olden days, when television was watched once and then you moved onto something new, there was no concept of being able to watch something again. Unless the BBC or ITV decided to repeat a show, you had one chance to watch it and that was all.  There were no video machines, and so the best you could do was to make an audio recording of a favourite show so you could listen to it again ... but a second best was to take photographs of the television screen.

I was doing both! From around 1974 I was recording DOCTOR WHO on audio each week. My dad had a decent reel to reel setup and he also had the technical knowhow to wire the system into the gubbins from the back of an old television and allow for direct recordings to be made of the tv sound. Some people had to hold a microphone up to the television and insist that everyone in the room be quiet ... but I had no such worries.

Then, from around 1975 I started to get into photography. and by 1976 I was out interviewing Terrance Dicks and Malcolm Hulke for my fanzine. and then in 1977 it was fanzines all the way!! And the first DOCTOR WHO convention in August 1977 paved the way for more photographs and better kit!

Thus I started to dabble in taking pictures from the television set. And it wasn't as easy as it looked! First of all, of course, you had no idea whether what you were taking was actually coming out. A roll of film had to be completed and then sent off or taken to the chemists to be developed and only then did you know if it had worked or not.

Trial and error revealed that you need to slow the shutter speed down. Television (or at least good old 625 line television) is not comprised of a single image. There is a pattern of dots/lines and these refresh themselves every so often, so in order to get a photo of the whole image, your shutter speed needed to be slower than the speed it took the image to refresh.

Also, I discovered that a camera with a SLR system was better - you could actually see the image you were taking through the eyepiece.

Because you had to slow the shutter speed, you also needed a tripod to ensure that the camera was steady, otherwise blurred shots would result. And sometimes, you'd get some photos which were double exposed as you pressed the shutter when you saw a good image, but at that second it changed to a different image ... and you ended up with both on your film!

A recently discovered a load of 'failed' double image pictures from DOCTOR WHO and realised that today, with digital cameras and computers, there was no need to use a camera/tripod/film any more. Any image you want can be taken direct from a video file with a Screen Capture ... and of course you would NEVER get a double image this way - unless the director had done a fast cross fade so there was actually two images on screen at the same time.

So I thought, before I bin them, I'd record these images here. All taken with my SLR camera, on a tripod, poised in front of DOCTOR WHO being shown live on the television ...

I've probably got more somewhere ... so enjoy ... the accidental fruits of the lost art of taking pics of a live television transmission!
