I'm not really sure were to post this thread but I think this may do. I'm gonna shoot a band (again) soon and this time I want the hardcore band to look hardcore. Exactly how I will take the photos doesn't matter. What matters is how I'm going to get them all dirty and sweaty. Of course I'm talking about fake sweat and I think I have an idea how to make it using some kind of oil, water and glycerol (I have a recipe on another forum), but what should I use to make them look really dirty? It has to look pretty natural. What should I use and how? Preferably would be something that comes off in the laundry as they wanted white shirts or something. I'm open for ideas!
