    Ok I am wondering is anyone has any suggestions as to how these half domes of light painting were formed ?

    It is really annoying me !

    I think it may be a machine.. that swings a silicone ball, with embeded light, on an attached string as it turns around bouncing the ball off the ground. either that or it may be a person doing the swinging and bouncing.. but the domes are too small for that I think...

    Yes but why do they have a hole at the top and the one on the jetty has no back to the dome.

    they are so symmetrical it would have to be mechanical somehow.


    very strange

    Nope it is not photoshopped in afterwards. These guys are light painting purists.

    The hole at the top is probably just a function/feature of the machine as it turns 360..

    the reason it does not have a back is probably because the light source does not shine(backwards) where the string is attached.

    I can't for the life of me work out how you'd do this.

    My friend is going to have a think about it, but here's a couple of tools that lightpainters use, which may give you some ideas:

    I'm thinking along the lines of an arm which sweeps back and forth in the vertical plane while rotating 360 deg on the horizontal. If the arm was offset from the center of horizontal rotation it would account for the "hole" in the top.
    Not sure about the back not being filled in. I'm thinking to dust off the old lego robotics kit and seeing if I can rig something up....
