Monolithic Optical Prism Casting Rainbow Spectrum on Playa

Full prompt

A 3:4 aspect ratio portrait art print composition presenting a massive triangular optical glass prism standing upright in an arid cracked-mud playa basin. The low setting sun strikes the glass corner at an acute angle, refracting an intensely saturated spectral rainbow beam across the foreground hexagonal mud fissures. Centered vertically with elegant vertical balance, the flawless crystal monolith reaches into a pale lilac desert twilight sky with wispy cirrus clouds, providing calm negative space across the upper frame suitable for editorial publishing. Hyper-detailed reflections, internal dispersion physics, and dry tactile earth textures are captured with razor-sharp medium-format clarity.
