Didn't see your post because I have you on ignore. But did open up one so here goes.
For stills I used strobe lights. Usually 1 @ 6 o'clock and 1 @ 2:30 o'clock to the girl. The front light was my key light and with an exposure meter set the aperture of the camera. The side light was usually half a stop higher than the key light and filled in the background and lifted the girl off of the background. Front light had a soft box and higher than 6 foot the side light same hight and through a shoot through umbrella.
For video I used cheap lights they use to illuminate buildings, builder use them and great for small rooms. Used a similar set up with both on shoot through umbrellas. Again using a light meter to get exposure right. You need to balance the video camera to get the color right. Easy today with digital video.
I see lots of posts from photographers saying they don't need or use a light meter. Without it your relying on knowledge you might not of built up and hit and miss. Using a digital camera and taking a series of test shots still leaves a photographer the task of taking level readings from lots of different areas to see if the light is doing exactly what he requires.
I see shots for top glamor sites where the exposure on the face is too high or the exposure on the feet too low. The over all lighting is uneven. All this can be found out by using a light meter and taking readings from all points of the model, head to toe. And points of the location. A goof light meter will also read reflected light. This is light that hits the lens and cases this effect.
Near the top on the left is flare coming off a back light. Also the picture is soft, not the effect I wanted. If I want soft I use a diffuser filter so I can control it. That mistake cost me money.
And made me more aware of the benefits of using a light meter.
You can't shoot good pictures using lights that are meant for video. Buy some strobe lights, books on lighting and experiment to get the lighting set up you like.
All rooms and locations will set their own problems and demands. Shooting into a white wall is going to give a totally different lighting to shooting into a black wall or no wall at all, like a large room of outside. Shooting in the forest is different from shooting in a wheat field.
