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. You get 12 Rulers, with both metric and English units on one side, and each with 6 action flicker pictures on the other! That’s 72 Flicker pictures all together! Vivid color and exciting action.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. If you don’t care about the ruler on the other side, you can easily cut this with scissors into 6 different flicker pictures! Here’s the kicker! We are not just sending you one of these rulers, we are sending you 1 Dozen rulers. And the last one is a train going down the tracks.Įach picture is 2 inches wide by an inch high. The fifth one is a sports car racing around a bend in the road. The fourth is a roller coaster in an amusement park with the roller coaster coming toward you down the track and the Ferris wheel spinning. The third is the space shuttle zooming around the earth and rendezvousing with a satellite. The second is a huge semi truck driving down the highway.
The first frame is a trolley street car moving down the track.
It’s difficult to capture on a still photo, so you have to imagine the dynamics of these flicker animations. It creates the illusion of a moving image as it changes from 1 phase to the next. It has 6 different photos, all with 5 Phase Animation. Technically it’s called lenticular printing.
The simple 2 phase ones are like a winking eye, but this has 5 Phase Animation on a 1 foot ruler. This is one of those pictures that you toggle back and forth and it animates the image.
