How do I shoot a close-up product video with a white background? Here are the basics on how I do it. The biggest secret is to soften the light by shooting it through an umbrella or similar scrim (such as the type included in a 5-in-1 reflector.)
I use a foam core poster board for the background, mounted to a table with spring clamps. My favorite light for this task is the Aputure Light Storm COB 120t which we reviewed a few weeks ago. I boom the Light Storm above the poster board with a C-stand and shoot the light through a white umbrella. This makes the light incredibly soft and prevents those distracting shadows.
