We want to see nice texture shots of milk splashes. We do not want to see a cow or a Milk bottle - just focus on the splash and the texture of the milk. Don't mix the milk with other products like food coloring or other items visible. If you have the option, set your shutter speed high to "freeze" the splash of the milk midair!
No people in the pictures.
Very clean and pure pictures
