Macro Blue Globe Thistle in Dark Backdrop

Ultra-detailed macro photograph of vibrant electric blue globe thistle flowers (Echinops) against a near-black velvet background. Focus on one or two spherical heads with densely packed florets and sharp spiky bracts. Highlight intricate textures, fine needles, and tiny dew droplets catching cool blue highlights. Use dramatic side lighting to create high contrast with a subtle rim light, and a creamy bokeh background to isolate the subject. Shot with a macro lens (~100mm), very shallow depth of field (f/2.8–4), crisp foreground and smoothly blurred backdrop; low ISO for clean detail. Color palette dominated by cobalt and sapphire blues with accurate white balance. Composition should be tight and intimate, filling the frame with the bloom heads while minimizing background distractions. Photorealistic, 8k realism.
