Start with a book on studio lighting. To begin with your assumption that
main and fill should be equal is wrong. However there is no reason you can't
use lights of equal power simply set up to give you the ratio you want.
A book will show you set-ups and power ratios so that you don't have to
re-invent 100 years of lighting for yourself. There are a few lighting books
on the following page.

How many watt seconds do I need? I'm using a 35mm film camera. I'll be
shooting in my single car basement/garage and a smallish living room.
Ambient light from sun is dim, EV4 at 100 ISO for both.

I'd like 3 lights, main, fill and hair/bg/kicker. I assume the main and

fill
should be the same w/s but how many w/s should the other light be? I'm
trying to come up with a ratio like 1/2 or 1/4 as many w/s as main.

I also want more than 3 power levels. I think this would be more

versatile
and may be a necessity since I don't have room to move lights further

from
the subject to reduce power. What do you think?

I apologize if this question is vague but I have never purchased studio
lights before.
Thank you for your help.

A really nice feature, perhaps more important than ws is can you
independently adjust output to each of the heads. I have a 1200 ws
Power pack but can't independently adjust the lights, other than to
move them back or forward or use a louver inside the softbox.

1200 is good and strong for 100 asa. More is better if you can afford
it.

Start with a book on studio lighting. To begin with your assumption that
main and fill should be equal is wrong.


I was referring to rated power not the ratio of main to fill.

However there is no reason you can't
use lights of equal power simply set up to give you the ratio you want.

Which of those books would tell me how many w/s to buy (taking into account
the size of the rooms I list above)?
Thank You,
