I could explain it as a freehand move when you stand on the "side" of the person and put your hands infront of there face "as if all your fingers lined up in a strait line ... at this point you make small circles as if your target was lookind down a long tube.... or tunnel... yea? well what if the hand farther way from the person did a larger circle than the one close... ... then switch... its like a black hole effect.... but with light...
sorry if that doesnt make much sence... i got gloves... and some friends with cameras .... video soon enough...
they do its just they might be faceing away from the camera... for those shots its all about angles... take multiple shots and just hope to get a good one that looks great...
")
most "finger lights" that just have a on switch only have the "solid pattern"
to get the "dots" the lights turn on and off really fast... Most LEDS like Inovas for example have 2 or 3 modes...
Simply enough... check out Modifled LEDS and use those ... and if you want to put them in gloves and use them as "finger lights" you could do the same....
