A real photograph in soft-shadow studio packshot photography, captured on a full-frame sensor with a 60mm perspective, deep depth of field, clean fine grain and true-to-life surface texture. One large softbox above-left casts a compact attached contact shadow that gradually broadens into a soft directional penumbra across a seamless matte sweep. Gentle shadow gradients ground the form while preserving readable support points; neutral colour and restrained contrast keep the finish natural.
Square 1:1 frame. A bicycle puncture patch kit as a small flat round tin with its lid open beside a rubber inner tube patch, a small piece of sandpaper and a tube of glue with an unmarked white tube, seen from above at a slight angle.
Isolated on a fully transparent background: alpha = 0 everywhere outside the object and its shadow, not white, not coloured, no checkerboard pattern, a real alpha channel. The whole object sits fully inside the canvas with a clear margin of transparency on every side, its outer rim fully transparent and nothing cropped by the frame. In place of a sweep, a soft semi-transparent black contact shadow in the alpha channel, darkest where the object touches the surface and fading outward to nothing, is the only ground cue. No lettering, numbers, logos or markings appear anywhere.
