John Woosley Posted June 9, 2019 Share Posted June 9, 2019 Hey everyone, I'm going to be shooting some drone footage in a few weeks of a backyard, and the idea is that there would be a layer of fog on the ground to make the setting seem like some kind of alien landing. I'm going to be shooting this in the summer in the US, so pretty warm temp wise, so if I did have a fogger and put it through a chiller would it even lay down in such a hot environment? Whats the best way to achieve this? Link to comment Share on other sites More sharing options...
Phil Connolly Posted June 9, 2019 Share Posted June 9, 2019 Chilled fog will rise when it heats up. On a warm day its not going to stay cool for very long. Perhaps if you shoot really early in the morning and get the fog really cold it will stay low enough, long enough to get the shot. Link to comment Share on other sites More sharing options...
Premium Member Aapo Lettinen Posted June 10, 2019 Premium Member Share Posted June 10, 2019 I haven't tried this but would it work to wet the grass thoroughly so that the surface would cool down a little when the water evaporates and the fog could maybe then stay a little longer?

Phil Connolly Posted June 10, 2019 Share Posted June 10, 2019 Yeah wet grass might help - along with lots of cold fog, that would help cool the ground too. How are you chilling the fog? I've had pretty good results pumping it through a box of ice cubes. Link to comment Share on other sites More sharing options...
Brian Drysdale Posted June 12, 2019 Share Posted June 12, 2019 Dry ice tends to lie in a layer. Link to comment Share on other sites More sharing options...

Premium Member Aapo Lettinen Posted June 15, 2019 Premium Member Share Posted June 15, 2019 (edited) Yes dry ice mist tends to lie low close to ground but I would worry about it being white so it can actually be seen in the image as well. If wanting to use dry ice one could first wet the grass and then throw dry ice grains around. Here they sell dry ice either in blocks/chunks or small grains. The grains have been easier for fog effects use for us when needing to throw the dry ice around, no need to crush the big chunks to get usable size bits Edited June 15, 2019 by aapo lettinen Link to comment Share on other sites More sharing options...
