Shooting faster means that part of the picture is unilluminated. This shutter will capture all the instances when the lights are fully on during your photo. In America, that means shooting at 1/60th of a second or less. ![]() The easiest way to eliminate these scanning/flickering lines from your pictures is to use a slower shutter speed. the slower shutter allows all the lights to burn into the exposure. In that case, each diode in the LED simply isn’t turned on at the same time. On older models of cars with LED headlights, you may make a picture and only some of the headlight will be illuminated–older Tesla Model S’s had this problem. It may look like a stripe or many stripes of bright and dark in your picture. If you shoot when the power is off, you’ll see the difference in the photo. The issue becomes apparent when you use a shutter speed that’s out of sync with the lights. ![]() Higher quality LED’s don’t do it, or at least not noticeably. You’ve noticed this with fluorescent lights when the ballast fails and you can see the light flickering–it’ll drive you crazy in an office. LED’s and fluorescents, however, are turning on and off 60 times per second. When we used older incandescent light bulbs you never noticed a problem when you shot indoors because those bulbs use heat to make light, and the alternating power wasn’t off long enough to cool down the filament in the bulb so that it was noticeably darker, even at fast shutter speeds. In countries with 220V power, it’s usually cycling 50 times per second (50 hertz). In countries using about 110V in the wall, it usually cycles 60 times per second (60 hertz). Alternating means the power is literally cycling on and off continuously. The power that comes from the wall is called AC power, which stands for alternating current. Fortunately, there are a couple of things you can do to mitigate the problem. It’s a problem with electricity and LED lights and fluorescent lights. ![]() Why are there colored lines of bright and dark in your indoor and nighttime pictures? How do you get rid of them? Don’t worry, it’s not a problem with your camera.
