Synthetic Bismuth (photomacro-photogrammetry)

sketchfab

Locality: in a state-of-the-art lab\nSize: 5 millimeters x 4 millimeters x 3 millimeters\nFormula: Bismuth\nAbout photomacro-photogrammetry: Boundaries between close-up, macro, micro shots are blurry, and definitions vary widely depending on the source. This debate rages on endlessly. Generally, the classification is based on equipment used to capture images.\nBelow a 1:1 ratio (e.g. 1:2) is considered a close-up photogrammetry\nGreater than 1:1 ratio (e.g. 5:1) is called photomacro-photogrammetry (sometimes referred to as macro-photogrammetry)\nUsing microscope optics yields photomicro-photogrammetry, regardless of the magnification factor\nDescription: A synthetic bismuth crystal showcasing a unique "stair-step" structure in a square or rectangular shape, grown in a lab. Iridescence colors (with hues of blue, green, purple, and gold) are generated by light interference within the oxide film on its surface.\nConcept & 3D-modelling by Dr. Andrei Ionut APOPEI
