HOWTO: Prevent crappy TV images in your photographs


Ever notice how older-model televisions and monitors have that scanning-in-progress look in video and photographs? That’s because your lens is literally capturing the set in the middle of a screen refresh. You can avoid that effect with some camera adjustment.

televisionThe Digital Photography School blog explains the capture science behind trying to capture non-LCD/plasma TVs, CRT monitors, and other display devices:

The screen on a TV is rolled down one pixel at a time at lightening speed. Use a speed of 1/30 or slower to catch the fully ‘rolled out’ screen of pixels.

If your camera doesn’t allow you to set a shutter speed, take a look at the automatic modes. For example, ‘sports’ mode wouldn’t be any good because the shutter is too fast.


Got experience shooting with older, electron-beam-powered monitors in the frame? Do tell in the comments.
