I have a shoot where I'm thinking about using a Tiffen Smoque filter. I want the smoqued set look but we don't have the resources to do it for real, apart from amateur fog machines which are hard to control. Also, fog on set is not a very pleasing of healthy thing. But I'm wondering if I should really use an on lens filter or if I can get the same effect in post? I've never tried to get this effect in post so I don't know if it's possible to do it convicely or as convincing as the glass Tiffen Smoque.
But the good thing about doing it in post is that I can control how much softnening of the image occurs etc. If I could get the same look and the post effect wouldn't look more fake, is there ar reason to go for the glass filter?
