M3 Reset black paint/exposed copper to make old

We use black paint as the base, with delicate manual polishing and precise aging treatment, to present a natural and smooth transition layer of paint wear - without deliberate scratches, only a soft patina like the sedimentation of time. Every exposed brass substrate has undergone meticulous darkening treatment, forming a warm and powerful contrast with the black paint, as if carefully rubbed in time, yet maintaining a precise mechanical texture. At ZengCamera, we always believe that good work comes from an extreme observation of details and a full passion for creation. Our antique craftsmanship is not simply about wear and tear replication, but based on a deep understanding and emotional resonance of the texture of time: we capture the traces left by time with our hearts, inject this understanding into every paint surface and every piece of metal with our hands, and let artificial craftsmanship present the vitality closest to natural time. Under the light, the depth of black paint interweaves with the dark gold of brass. It is ZengCamera's persistent expression of craftsmanship aesthetics - we use emotions and details to give each piece a unique temporal texture.
