Hello Wise Listers, A filming crew has requested to use a DF-50 Diffusion Hazer in one of our period room exhibitions. It uses food grade mineral oil to put micron size droplets into the air to create a "hazy" look. My initial reaction is to deny the use of this machine. Does anyone have any experience with this type of machine? Thank you for your assistance!
