This look was likely made by placing the flower or petals on a translucent surface and lighting from underneath. A translucent table would work, but you can improvise with materials like thin white styrofoam, frosted perspex/acrylic, white paper, tissue, or white fabric stretched over supports.

Key points:

• Put the flower head or petals on a diffusing surface.
• Place a strobe or continuous light under that surface, pointing upward.
• The diffuser helps create an even white background and reduces flare.
• If the flower is thick or not transmitting enough light, add another light from above or the side for fill.

Cutting off the flower head and arranging petals separately may make the effect easier to control. The bright, glowing result comes mainly from strong backlighting through the petals, with diffusion to keep the background smooth and white.

So no, you don’t necessarily need a specialized translucent table—just a translucent support plus strong, diffused light from below.
