Hello all,
I've seen several posts on creating the illusion of police lights, but not much on how to expose for them..

I have two night shots, one exterior and one interior.

For the exterior shot, I will have two real police cars w/ iights flashing in a driveway. The yard and house will have some lighting (Mole nine lights, not sure). How do I meter and expose for all of this?

The interior will also be lit sparsely, a faux moon light through a window sort of thing. The walls
will be bouncing the light from the police lights.

I have no idea how to prepare for this, it is a rather large night in terms of production.

Super 16, primes. 500ASA Vision 3.

Thanks so much

Bill

If your digital spot meter's response time isn't fast enough to meter the police light's cast, then maybe try using an old analog reflective meter (pointed at a gray card receiving the light's cast). You can watch the exposure needle swing back and forth as the light varies, and easily get a feel for the average reading for the red and blue. I did this back in the 90s when metering for light being caustically reflected off water and it worked great. Hope this somehow helps.
