Three lights make a studio setup work: a key light for main illumination, a fill light to soften shadows, and a backlight to separate your subject from the background. One practical setup uses two lamps and two floor lights angled at the wall for warm ambient glow.

So whenever it comes to lighting, there are 3 main points that you want to focus on. The first light is your key light. This is the light usually directly in front or on the side of the subject. The second light you're going to want to set up is called a fill light. So your key light might produce some harsher shadows at times. So this is why having a fill light is important. It fills up all of the shadows on the face, all the shadows in the background, just the hair. To make it look more natural. The third source of light that you want to focus on is actually the backlight. So this is what separates the subject from the background even further. In this case, I have this lamp over here to my left. I have another lamp to my right and have two floor lights that I have on at all times that are out of the frame shooting up the wall to give it a little bit warmer of an effect.
