Of course, the nature of the room in which you are photographing also makes a big difference. If you happen to be photographing outside, then that makes things more straightforward, but if you shoot inside, the amount and direction of light that can enter a room makes a big difference. If you are fortunate enough to shoot in a room that has many windows and skylights, you should have plenty of light and not have to resort to much artificial lighting. If your room has just one or two small windows, that's simply not going to be enough light and you'll need to depend heavily on artificial light.
We good so far?
