theres a few people had asked me about how i did the light graffiti i did for birthday wish to my friends. my reply was
"the light graffiti i did was using abode after effects, which u have to animate the light by yourself actually. theres one tutorial on youtube on how to light writing in motion, its much easier method. check this out.
check out pik-pika and lichtfaktor for photography technique
enjoy light writing! "
This is the one I did. http://www.youtube.com/watch?v=WIk5FkWeqio
yes, theres a easier method, the one i did took me 3 days straight just to animate the light. I havent try this method myself yet but, this is really much simpler method and looks real because is real light from source instead using animated light.
