That's a pretty nice pic, the mist is so solid looking. Since it was hailing, it could be that the camera captured the mist created from the warm air inside hitting the cold air outside. I wonder if the camera could capture natural mist easier than we can see it? Where was the light coming from, a flash, porch light? I'm thinking that the light might enable the camera to magnify 'natural' mist. Did you take other pics at the same time?
Thanks for sharing your pic. I like your site too.
