I will be shooting with this stock for this first time (with fuji for the first time as well) and I'm curious, for an interior scene, what is the minimum amount of light i can use and get good exposure?

I will be shooting 16mm with the aaton xtr

a 2k is probably the largest light i'll be able to get my hands on . . . if that

i would love to be able to read a 4.0f


thanks

-ryan

Depends on the room and how you want it to look... If you had big windows in the room, for example, with nice daylight coming in and some CTO.. well then you might not need any lights.
If you're out on a street in the evenings... and need to keep it cheap, NS or VNS bulbed ParCans will probably in order (if the largest light you can get is a 2K...)
What I often do is try to just up the wattage in some of my practicles (i never spell this word right) and then set a nice key with something..
Like everything in film, what is "right" or "needed" is dictated by what you're shooting, how you want it to look, and how you want to work.

Depends on the lighting technique - a 2K shined directly at someone from a couple of feet away should get you plenty of stop at 160 ASA, but through a 4'x4' frame of heavier diffusion, or bounced off of a white ceiling... now you're more likely to be at a T/2.8.

But you got more depth of field with 16mm so you don't really need an T/4.0 unless you are going for deep-focus effects. Or you have a very slow lens on.

The rule is that it takes 100 footcandles to get an f/2.8 at 24 fps with a 180 degree shutter using 100 ASA film.

IMO, Fuji stocks are a little grainier than Kodak's. You may want to compensate for that rating your stock 2/3 of a stop over, or 100 ASA and follow David's suggestion.

thanks for all the help . . . i'm not looking for heavy shadows . . . primarily hey key lighting . . . i was hoping to be able to read a f/4.0 because it would allow me to rate it at least 2/3 over and still get a decent read. So i guess the real question is how can reach a minimum of 100 footcandles? I hope that makes sense.

daylight pouring through windows is something i've been pushing towards, but i just want to be prepared if the director definitely says NO

thanks again

Do a prelight a few days before shooting, and figure out what you'll need.
