exposing for fire and explosions

[Nantia]

im shooting a film, soon, and i was wondering about exposure, when it comes to fire and explosions .Im shooting a day time car explosion, and interior and exterior night shoot of a 10 story building on fire, using 16 mm film, any advice on how to expose for that?

well i will answere my own question! i found its best to underexpose by 1 to 2 stops, depending on the distance and size of the explosion. I will later post stills and the f stop, film stock etc of each still, so u can get an idea on what worked and what failed!
