Taking Photos of TV screen events
Sep 3, 2017 08:55:17 #
As a long time tennis player (no longer active due to age) I( am addicted to the US Open tennis tournament and have purchased 4 days of tickets for many years including this one. I then create my own album of the event. However, this year ill health makes it impossible to attend even though I have the tickets. So I thought I'd try and still create an Open album by taking pictures of my TV set coverage.The results are mixed to say the least.
My equipment is a Sony A6300 with the kit lens and a Tamron 18-200. My difficulty is in choosing a shutter speed. Around 1/300 - 1/340 works for fairly stationary shots but motion is frequently blurred. If I increase the speed I get some strange intermittent results -sort of a sepia overlay. I'm wondering if this is catching the TV picture in some sort of transition. Also I seem to get somewhat better results from my computer screen than from the 32 inch TTV.
So does anyone have experience withis and can offer suggestions?

It depends on what TV set you have and whether your watching a standard definition or a high definition video feed. Most TVs have either a 60Hz, a 120Hz or a 240Hz refresh rate if I'm not mistaken. So, that being the case I'd start with a shutter speed of 1/60 and see how that works.

i would try 1/60th second at f 5.6 or f8 and see what your results are.
good luck, and i hope you recover enough to attend next year's open.

Most broadcast events carry a disclaimer that goes something like "The following broadcast is intended for the private use of our viewing audience." As long as he is using it for his own viewing pleasure I would think it's the same as recording it on his DVR.

yES,I'm using the photos purely for my own aND MY son's enjoyment (we share a lot of photos) so I'm sure there's no copyright infringement. I'm going to try the `1/60 s3cond suggestion although I think that's going to be too slow.

The motion is blurred on the TV as well. If you take a video of the TV set you won't see the blur, but if you take stills from the video you will see the blur. In video or while watching the TV our brain doesn't register the blur. Still photography does at fast shutter speeds, but because what is being broadcast on the TV is not at a fast shutter speed like it would be for stills in person, you can't freeze the action to eliminate the blur.

Yeah, the frame speed is 1/60 of a second or there about. You can't go with a higher shutter speed and improve on the "stop motion" aspect of that video presentation; it is what it is. And as was pointed out above if you freeze a single frame of the video on your DVR there may be blurred motion present.

Thanks for the quick response everyone. The 1/60 of a second seems to work pretty well especially when there's bot too much movement. So while I can't get the action shots that I'm used to when I'm there I will have a photographic souvenir of the 2017 Open. Again, thanks for the explanations and help.

Pre Digital, the guidelines for TV screen copying, used to be...Shutter speed 1/60th. That allowed 1 complete scan on the TV screen. Any faster shutter speed would result in a part picture, because a complete scan had not been captured. I think US and UK lines per scan/picture were different, A figure of 605 lines seems to ring a bell in my 81 year-old brain. Best of luck with your project.

If you can get it on your computer screen, you can do a screen shot - PrintScreen. That will give you more control.

Everyone worries about copyright laws, watermarks, releases, and insurance. First if you do not have at least $50,000 per incident to enforce your copyright you are flat SOL my friend...ditto for patents. Photography is very difficult to sell today, so proving any monetary damages in a given local is next to impossible.
Second pulling one or two frames off of a video would be so hard to detect where and when it came from. Unless you are awash in cash and assets, no sane lawyer would even entertain a lawsuit. The chances of collecting any damages would be near zero. You can sue anybody, but the chances of collecting a dollar are minimal, so relax and enjoy your photos.

I got pretty good results using my iPhone watching the Soldheim Cup. May have something to do with the tv. I don't know enough about it but my tv is a recent purchase, is HD and may have a faster refresh rate.

I have had good results with first pausing live action on my tv and then taking the shot. I just have to watch for glare on the tv screen and not use a flash.
