One soft light source and a reflector cover most beginner indoor needs. Place the light at roughly 45 degrees and watch how shadows fall on a face.
Dim overhead bulbs that fight your key light’s color. Mixed color temperatures make skin look odd and are hard to fix later.
Practice with a patient friend for twenty minutes instead of buying more modifiers. Skill multiplies gear; gear does not multiply skill by itself.
Keep cables taped and stands sandbagged. Safety is part of professionalism even at home.
