iridescent curved form abstract photograph

[iridescent curved form] photographed as a large, glossy mass that occupies the lower half of the frame and sweeps diagonally from lower-left toward the right edge of the image. The subject is placed low and left-of-center, leaving generous negative space above and to the right so the background fills roughly the upper two-thirds of the composition. The surface is described as a [smooth reflective surface] with subtle micro-structure and soft specular gradients catching color. A [thin rainbow highlight] runs along the outer rim with cool teal, warm gold, and magenta shifts, providing concise accent lines against the dark field. Light is rim-lit and soft, producing gentle falloff and delicate reflections rather than hard shadows. The background is a [deep charcoal background] with near-uniform tone and very low texture to keep focus on the subject. Render the scene as clean abstract-photography with naturalistic material response and minimal grain. Keep edges smooth, tonal transitions subtle, and overall mood moody and refined.
