Firstly, ensure you have a clean, wrinkle-free white backdrop. This could be a paper background, a fabric sweep, or even a large white wall. The key is to have a seamless transition from the backdrop to the surface the product is placed on, creating a smooth, continuous white space. Position the backdrop so it extends beyond the edges of the product frame, eliminating any visible corners or edges.
Secondly, pay close attention to your lighting setup. Use soft, diffused lighting to evenly illuminate the background and avoid harsh shadows or hot spots. Positioning your lights to the sides of the product, with reflectors if needed, can help create an even spread of light across the background. Adjusting your camera's white balance settings can also help neutralize any color casts and ensure a true, pure white is captured.
