In three weeks i'll be shooting a short film, in MiniDv (with a Panasonic dvx100). The story takes place inside a moving car (at least 75% of the shots), and it is necesary to have good exposures both inside the car and the background.
In order to make the production easier, we decided to use a chroma key and have the car still. This method would allow us to use different exposures (assuming the different ammount of light) for the inside and the backrounds, (which, given the extremely short budget we're using, is very useful because it allows us to work with little light on the people inside the car). We are planning to light up the interior of the car with mirrors and white surfaces reflecting the sun's light.
The exterior shots will be done in a "traditional" way, with the car on the road and we'll be using natural light.
This will be my first time using a chroma key. Which considerations you recommend me to take in order to minimize any trouble I might have?
thanks a lot for any comments and suggestions.
