Answer: Greenhouse glass texture (macro)

What you're looking at

Greenhouse glass is a common building material you'll find covering garden structures, plant nurseries, and agricultural facilities around the world. It's designed to let light through while protecting delicate plants from the elements, making it an everyday part of many gardens and farms.

When photographed at extreme magnification, greenhouse glass reveals an intricate landscape of tiny ridges, waves, and imperfections across its surface. These textured patterns scatter light and create depth, making it nearly impossible to recognise as the familiar transparent material you see with the naked eye. The close-up view transforms a simple sheet of glass into an abstract pattern of light and shadow.

Look for regular, repeating surface patterns and how light refracts through translucent material when zoomed in extremely close.
