I'm shooting a night time scene with 2 characters talking inside a car.
The car is parked, the windows are wet from a recent rain (but it's not raining anymore).
I'm looking for tips and advices for enhancing the water drops.
Here is a screen grab from tests I've shot on a 5D a couple of days ago in a studio (we're gonna shoot on location for the actual shoot, with a RED One) with the kind of lighting atmosphere I'm planning to do.
No one was really in charge of the rain drops for this test, so we just splashed water on the window before shooting.
My first question is about the best solution for spraying water on the windows.
I was actually thinking of using a water sprayer filled with a mix of water and glycerine (like we usually use for sweat on faces).
Any other idea or advices for the best mix to put in the tank ?
My second question is about lighting those drops.
I know that you don't actually light raindrops as they are transparent, you just need them to register an image as they act like a lens.
I don't want to have a very lit background (probably a bit darker than the test shot) to keep the drops brighter than the background itself.
My idea was to shine light on a large muslim sheet (or a kino 1 bank) placed low behind the car, so it doesn't affect my lighting and contrast inside the car and create a white line on the top of the drops so they exist on this dark background.
I guess they will probably also register the lights I use for lighting the characters.
Am I on the right track ?
I'd love to also add some colour bokeh with a small fixture far away in the background.
What kind of source would you use for that ?
The director wants to place the car close from a (white ) house wall, I'm pushing to place it further so we have more depth in the back and we can isolate the 2 characters in the image.
Any advice or comment on my ideas are more than welcome
