I use a Panasonic FZ-28 for all my pictures. I only have one filter for the camera and that is a Neutral Density, which I haven't really gotten around to using yet. Its not a DSLR so I can't really change lenses on it. It has a Lecia lens and I can attach 46mm filters and secondary lenses to the front. The water drops are real water. It has something to do with the plant, which is one of landscape plants my mother has. IDK what it is exactly, but its kinda fuzzy and the rain always stick to it. I should get some little macro lens/filters to get really close to stuff.
