looking for advice on which is the best way to judge exposure for an explosion. the explosion is happening at night against a black sky. it is only tht flame element that we are shooting at this point and im wondering what the best way to take a reading is, as there will be test explosions allowing me to meter. thanks in advance for any help and advice

I assume it?s a fireball you are talking about exposing.

If so, typically at 400 iso you should be at a 5.6/ 8 split and you should be fine.

I find that if you ar eexposing for the fireball itself with nothing in th e FG or BG worth keeping at exposure then a deeper stop gives more detail/chrominance to the flame. the brightest part of the explosion is v. quick though so if you are not shooting 150fps or higher then the 5.6-8 rule works as it keeps most detail in the burnout.

I should have added the 5.8/ 8 at 24 fps, but you typically would be overcranking.
