Default laser pointer and light painting

I have one other question since i found this wonderful forum.....i enjoy taking night pictures....would it be safe to use my red and green laser pointers....in an attempt to do some light painting at night?
I realize it would not be wise to aim the laser directly at the camera......i am talking about light painting at night up against a wall?
I know a led light would be best.....but all i have at the moment are red and green laser pointers.
thank you

What you want to do is perfectly safe (especially the part about not pointing the laser at the camera.

The Laser Pointer vs. the LED Light is apples and oranges. You can hold the camera and point the lasers against a surface to get the image you want. For an LED Light, someone must be standing in the frame, waving the light around to get the image you want. The laser pointer method is simpler if you can get the images you want off the surface you use.

The green laser will be roughly twice as bright as the red laser, so taping them together may result in the red being washed out.

well i made my 1st very crude attempts at laser light painting

red and green.......green much brighter as expected......my problem was getting the shutter to fire in total darkness......i had to spot a section on the wall with a flash light.....to give it something to focus on.....so the shutter would open/close.

Switch everything to manual mode, including AF switch on lens to Off position (and IS off if the lens has it, saves on battery power)
Manually pre-focus with light source on, turn light off

Fire away!

Usually good for exposures up to 30 seconds, longer if you have an external timer remote cord.

you might be interested in making something like light balls!
Long video, the actual light ball images start around 11 minutes into the video

These are made with inexpensive led lights on a string
