My simple setup for yesterdays shot posted for Heather @365projectorgheatherb camera on a tripod, remote flash on a tripod, flash unit fitted with blinkers to produce a narrow beam of light to highlight the smoke and not light the background, https://365project.org/pcoulson/365-5/2022-02-09
@30pics4jackiesdiamond Thank you Jackie for your comment, my camera does not have a pop up flash so soon had to master both master and slave flash photography:)
@novab Thank you Nova, it really helps to narrow the beam, I use a similar technique for water splash shots but have one blinker on the camera side to illuminate the droplets and background only:)
Thanks for sharing! Must appreciated. :)
