the actual trick is simply making your camera’s shutter stay open a long time (literally 3-4 seconds), which captures the falling light trails from the burst. the application fee is $200.00 (be careful when you make the selection because any later request to change the examination type will charge you $50). thanks to everyone who has sent us pictures and video links! if you have a particular requirement in mind, or if you have designs / photos of your own that you would like to offer to others, please contact us.
