Ok before I say anything let me give credit for this idea to those that it belongs to. Most recently I saw tarcyliu post a pic with light coming from a cell phone. I had thought about it a while ago when I saw another member post a pic where he made a circle of red light with some matches. I can't remember his name but you all may have seen this pic that I am talking about so credit goes to him whoever he is. And credit goes to anyone else that has posted pics where they have captured light trails.
I started out originally wanting to write my name with a red lazer pointer using the longtime exposure settings of my camera-but it only goes up to four seconds and found it hard to try to write legible and quick.
So I almost gave up but then I remembered some movie about Pablo Piccaso where he and a woman are photographed painting faces in the air with the light from some lightbulbs. So I decided to just try to make simple shapes and words.
All I did was turn off the lights in my room and set the LT settings to four seconds and 'painted' on the wall, that my camera was pointed at, with the lazer pointer.
If you don't have one you can use just about anything that emits a light, your cell phone or matches (as those members did) a candle, some Christmas lights. Also turn on your camera and take your remote control and aim it at the camera and push the buttons. If you see the red light your camera is able to capture IR so see if you can use the remote in place of the laser pointer. You could try multiple types of lights at the same time a lazer pointer and the light from your cell phone for example.
I have an idea for something using this idea but I will post it later. I just put this up to see if any members here want to play around with this idea I am curious as to what you guys and gals can 'paint'. So give it a try and lets see what you can come up with.
