Really incredibly good photos - Thank you!

In the photo I might know wom_fire_sillouhette unusually lot of detail for such a "long" exposure time. they are not as washed out as the flames on the right side and you can see very well the smoke. how does this come about?

The speed at which you "light paint" affects the level of detail :)

Revisiting this post for research. Really awesome stuff here.

Some of the images above looks like 3d compositions. You've done really stunning work!!!

This is great stuff! I do have one question:
How did you preserve the texture in the flames at 17 seconds in the Wom_fire_cloud_von_wong image? I would think that the flame would be very blurry at that slow speed.
Thanks for the inspiration

Hey Tim, sorry for that it was actually 1/1000th of a second. Looks like I wrote it wrong! updated :D
