Hi,
Has anyone else here tried canned smoke?
I ask because I've finally put the videos for my new laser up in this thread: http://photonlexicon.com/forums/show...0111#post60111
..and whilst the beams when projected onto a surface have extreme brightness (I even went to see an optician after filming the 2nd video - filmed 12 hours apart because on both occassions the diffuse reflection seemed to leave me with burning eyes - in the end we decided it was some kind of dry eye reaction with my contacts brought on my staring rather than any problem with radiation but it does illustrate the extreme brightness which isn't full captured in the video), the beams I filmed looked a little weak. The room was like a foggy day when I switched the light back on - I used a full can in a 10ft square room in under 5 minutes. However, I didn't fel the beams were as bright as expected although the graphics on the walll were extreme!
I knwo the camera / viewing position from behind the projector isn't the best place to observe / record from as it gives a much dimmer view although its the safest in a small room.
So my real question is, is canned smoke poor at reflecting beams?
I certainly didn't see the drifting smoke effect I've seen in many other videos of beams on here except whilst I was actually spraying close to the beams. The canned smoke seemed to be oil base like haze as it left a sticky residue everywhere (guess who was popular!).
I could understand the beams looking a little weak if the laser was dim, but man this thing looks extreme to me. Watching the graphic points on a line is quite hard as its so bright on a white emulsion wall. There s definite tendancy to squint / shift attention!
