My guess is that the answer is ... the rules don't apply, given the myriad
possibilities for indoor lighting. I have worked up a sketchy "electrical
16" based on my own experience. Here's how it goes:

400 ASA - my living room at night with the lights on - f/2 @ 1/30

I compensate from there. If the place I'm shooting is a little dimmer than
my living room at night, I'll open up 1/2 a stop; if it's a lot dimmer, 1
to 1 1/2 stops.

If its brighter - a gallery with white walls and bright lighting - I'll
stop down a stop.

The lighting in museums (where I enjoy shooting) I find too varied to be
able to come up with a practical "rule."

What kind of camera are you using, and why don't you have a light meter?
