an ultra-detailed vintage-style close-up photograph of the helmet of a Sephirot knight in a translucent, holographic form. The helmet shifts between near transparency and full density, glowing with an ethereal, neon-futuristic light in hues of pale yellow and faint green. Its intricate design features crystalline patterns and subtle geometric engravings, refracting light in fragmented, prismatic beams. Volumetric lighting enhances the surreal glow, casting soft, overexposed highlights and rich shadows on the helmet’s surface. The background is muted with a hazy, futuristic atmosphere, adding faint geometric patterns and blurred neon reflections that accentuate the knight's surreal, otherworldly presence.
