Cyanotype & Blueprint Aesthetic Prompts

Architectural blueprint of a Gothic cathedral, crisp white linework on a deep Prussian-blue ground, precise elevation drawing with flying buttresses and a rose window, fine graph grid behind it, dimension lines and handwritten annotations, a title block in the lower corner. Even drafting-pen weight, faint paper grain, vintage engineering-drawing mood. Flat-on orthographic view, high detail, monochrome blue palette.

Cyanotype contact print of a wrought-iron spiral staircase, a glowing white silhouette against a rich Prussian-blue wash, soft brush-stroked borders and watercolor-paper texture, sunlight-exposed photographic feel, gentle tonal gradients from pale cyan to deep navy. Slight uneven exposure at the edges, handmade darkroom mood, square framing, antique blueprint-era atmosphere.
