Hello Shel, When using studio lights, it is common to be shooting around F8-16 because of the power of the flash heads. The faster the shutter synch, at those small f stops, the less ambient light becomes part of the equation. If you are relying on the flashes for all of the lighting effect, it is nice to shoot as Paul describes.
When I was shooting the Pentax 67 with it's 1/30 flash synch, I needed to try to keep the room dark and only use the modeling lights in the flash heads.
