Macro Guitar Fret Dressing Close-Up

Extreme macro photography of a guitar fretboard during fret dressing. The middle fret is mid-dressing, showing bright [raw nickel silver] where the file has cut, with tiny metal shavings nearby. Neighboring fret ends remain square and unfinished for contrast. Razor-thin depth of field, sharp focus on the cut metal bevel, soft directional workshop lighting highlighting metallic textures and wood grain.
