Pink Contours of an Oil Film

A mesmerizing macro photograph of a single thin oil film on still water in a shallow black laboratory dish, cropped beyond the dish rim. The film forms large asymmetrical contour bands in muted magenta, pale gold and petrol blue, with one oval clear-water opening at lower right. Real optical interference produces delicate gradients and very fine dark boundaries; the surface stays flat and almost mirror-smooth. Soft reflected window light gives the upper left a silver wash. Sophisticated abstract material photography, not marbled paint or a digital fluid render, no bubbles, objects or words.
