How do you take a picture on a TV screen? kokuotak.., if you could answer this...?

Question

kokuotak.., you told me to take a picture on my TV screen on another of my questions...

Answer 1

1.
Do the photography in a darkened room to avoid reflections.

2.
Recognize that the TV actually displays a series of still images (called frames) that are displayed just rapidly enough to fool the human eye. The frames themselves are displayed one line at a time in a CRT type TV.

One approach is to use freeze the image and photograph the screen using tripod with a shutter speed of around a 1/4 second. This averages out a bunch of frames.

Another approach is to set the shutter speed to match the frame rate of the TV. In the US and other countries that use NTSC use 1/30 second. If you are in the UK or other countries that use PAL use 1/25 second. You will have to take a bunch of shots until you find a photo without a black band.

If you have a TV tuner in a computer, you can grab a frame using software rather than using a camera. On a PC you could probably just display the program and press PrtSc to put the image in clipboard, then paste it into a program like paint or IrfanView

Answer 2

Use a digital camera and turn off the flash...(if you can see the TV's picture)

Turn off your lamps in the room....

Take several pictures....one of them will not have the black bar that appears in the picture due to how the TV builds the picture....

If you must use the flash, shoot the picture at a slight angle off of center....the farther off, the less you see the Flash-spot on the screen...too far off and the picture loses brightness/contrast....

Then select the picture that shows the problems...TV techs like me can even look at a picture with a black bar in it....as long as we see the problem and you describe the problems too....(wavy lines in the vertical direction, odd color in upper right corner, lower left pulls up....)

Answer 3

this is a complicated question because of the various technologies used. There are a lot of actually stable articles on line in case you choose to envision each and every of the technical changes, yet right this is a precis. you will locate 3 considerable kinds of TVs out contained available in the industry: Plasma vs. liquid crystal exhibit vs. LED Plasmas have actual black shade, widest viewing attitude and the main astounding hues. So plasmas are stable for viewing video clips in a room with low mild at night. yet they get rather warm, use distinct electricy, and can burn out rather quickly interior of many years, so which you are going to be able to desire to change them faster. because of the fact of its power and value non-effeciency, plasmas are actually not a powerful investment. classic cathode LCDs, have a relentless backlight, meaning even black hues would be lit up, so LCDs are greater suitable in bright rooms interior the day. they are terrific in case you have a pastime console related and taking part in video games on it. LEDs are the maximum recent form of TVs. they are definitely one among those liquid crystal exhibit making use of similiar technologies yet a distinctive form of backlight, so which you get the comparable photograph high quality of a plasma without the burn in and making use of much less electrical energy too. LEDs are one among those liquid crystal exhibit exhibit screen, so it may even say LED liquid crystal exhibit on the field, so whilst buying TVs, in case you choose an LED, be effective it says LED and not purely liquid crystal exhibit. you would know because of the fact they are so a lot greater costly than the classic liquid crystal exhibit or plasma. in case you are able to locate the money for it, LED liquid crystal exhibit, no longer classic liquid crystal exhibit, provide the terrific high quality.
