AI image generated by FLUX.2 [klein] 4B — prompt: An ethereal macro photograph of a single translucent dandelion seed resting on a calm, dark obsidian water surface. A solitary, perfect golden water droplet clings to the filigree of the seed, refracting a miniature, inverted forest landscape within the sphere. The lighting is soft and cinematic, coming from a low-angle golden hour sun, creating ripples of amber light across the deep indigo water. Shallow depth of field with a creamy, blurred background, 8k resolution, hyper-realistic textures.
