Dark Cyberpunk TKL Mechanical Keyboard Product Photography AI Image Prompt

16:9 horizontal composition, top-down (about 60-degree overhead angle) mechanical keyboard product photography. Main subject: an 87-key / TKL layout mechanical keyboard placed slightly left of center, with a matte deep space black aluminum alloy case; keycaps use double-shot injection molding — alphanumeric and function areas are electric purple / neon purple keycaps, modifier keys (Shift, Ctrl, Alt, Enter, spacebar, etc.) are deep black keycaps, and the ESC key and arrow keys are fluorescent magenta / magenta accents. Keycap surfaces are matte PBT, with the black bottom layer of double-shot visible from the side. Around the keyboard are scattered several removed black and purple spare keycaps, plus a metal keycap puller. Desktop scene: the keyboard is placed on a dark gray / charcoal black cutting mat (surface with white fine grid line scale), below the cutting mat is a black desktop. At the upper left of the keyboard is a retro-style gamepad — the gamepad shell has a black matte texture, with neon purple and magenta buttons. At the upper right corner of the frame, the corner of a dark purple cover notebook is exposed. On the desktop are also scattered several black binder clips, a small hex wrench, and other small tool objects, adding desktop lifestyle feel. In the blank dark area at the middle-left lower part of the frame, several lines of white small sans-serif English annotation text are arranged vertically (extremely small font, similar to technical specification annotation style), content: “HOT-SWAPPABLE / GASKET MOUNT / 5-PIN RGB / PBT DOUBLE-SHOT / N-KEY ROLLOVER / 8000Hz POLLING”, one parameter per line, tight line spacing, left-aligned text, monospaced / industrial thin font, overall integrated into the composition as a design typographic element, not breaking the immersive feel of product photography. Overall color tone: black as the base, electric purple + fluorescent magenta as theme contrasting colors, cool tone, dark, cyberpunk feel. Lighting: the main light source is strong directional hard light from the upper right of the frame, forming an obvious diagonal light direction from upper right to lower left, creating clear bright side-dark side zoning on the keyboard surface. The lit surfaces of the upper-right keycaps show bright specular reflection, while the lower-left keycaps gradually transition to shadow areas, forming a strong light-dark gradient. The keyboard casts a clear hard-edged shadow extending to the lower left on the cutting mat. The cutting mat's white grid lines are clearly visible in lit areas and gradually disappear in shadow areas. The scattered keycaps and small objects also show a consistent upper-right lighting direction, each casting small hard shadows in a unified direction. Overall light contrast is relatively large (about 3:1), with distinct light-dark contrast but natural transition, not a completely silhouette-style extreme contrast. Around the frame there is an obvious vignette darkening effect (especially darkest at the lower left and lower right corners), forming a central bright, surrounding dark spotlight-tube atmosphere that firmly locks visual focus on the keyboard main subject area. The deep black desktop background absorbs most of the light, and only the cutting mat area presents a mid-gray tone due to white grid reflection. Overall style: geek desktop aesthetic product photography, dark cyberpunk color scheme, clean and crisp tech feel blending with retro gaming culture.
