This is a close-up, macro-level photograph of beach sand, located in Matosinhos, Portugal. The scene is comprised entirely of granular material. The subjects are individual sand grains, ranging in size and shape, mixed with fragmented shells and various mineral particles. The composition includes translucent, clear, and white quartz grains; irregular, opaque white fragments consistent with mollusk shell material; and opaque mineral grains exhibiting colors such as light brown, orange, reddish-brown, and dark grey/black. A distinct small blue particle is visible within the granular matrix. No people, animate subjects, man-made objects, actions, or interactions are present. The environment is consistent with the surface of a natural sandy beach under direct illumination.
