One of the final images from a stunning wedding recently in Clumber Park, Notts, UK. Made this image using white long burn smoke grenades from a paint ball supplier. Two bombs burning here being waved low to the ground by my assistant.
Lighting was a simple two light setup with SB910, 1st just right of cam and second left of cam to create contrasts across the smoke, manual mode 1/400 second exposure, ISO 200, f2.8 24-70 @29mm. SL triggered with the ever faithful PW Mini and Flex.
