Multi-pass product reflection composite

A fixed-view commercial composite of an unlabeled polished steel thermos flask and its glass-wool infuser cap on a pale sweep, every material lit to its own metered pass under one scrim. No letters, words, signs or logos anywhere in the image. A real photograph of a commercial product, built as a fixed-view composite from several tripod-locked exposures on a full-frame digital sensor, 90mm lens at f/8, one shared perspective and registration, deep focus, a noise-free commercial finish. The dominant light is a single large scrim from the upper left, applied in separately metered passes: one soft gradient models the metal, a cooler pass keeps glass translucent, a third lifts the label, every pass agreeing at each seam so the highlights tell one consistent story. The finish is pristine retouched-product rendering: each material separately readable, clean speculars, immaculate neutral colour.
