Thank you for your lovely comments; I’m pleased that my efforts produced some reasonable results as the 1st session proved awful! Here is a very useful YouTube “how to” that I should have watched before I started, it would have saved me a few frustrating hours!

What I found useful:
  • A darkish room so that you can see the smoke plume in the beam of a torch, for focusing, etc.
  • A torch for highlighting the smoke plume for visibility, not to illuminate it for the exposure – that will be done by the camera flash.
  • A well ventilated room so you do not choke on the smoke.
  • No breeze as the slightest wind makes the smoke deviate.
  • F8-F16 for max depth of field as the smoke plume moves and dances around.
  • Manually focus the camera; I used remote Live View tethered to my Notebook computer.
  • Dangle a white piece of cord down from the rafters in the plane of the smoke to assist with manual focusing.
  • Use an off-camera flash; I don’t have one so I had to increase the distance of the background to avoid it intruding through being illuminated by the camera flash.
  • Plenty of practice!
  • Don’t do this around a smoke alarm!
  • Double check that you safely extinguish any spent matches or incense sticks!
Some of the shots remind me of ghostly X-rays, quite spooky really!

Cheers

Dennis
