One Rosemary Sprig · Cyanotype Photogram

SUBJECT
One rosemary sprig reproduced as a cyanotype contact photogram, with a single slender stem and narrow needlelike leaves attached in paired clusters. The sprig reads as a pale botanical impression within blue sensitized paper.

COMPOSITION
Show the paper straight on in a vertical frame. Place the sprig diagonally from the lower-left toward the upper-right, fully visible and surrounded by generous blue space. Keep the coated field's irregular boundary visible inside a narrow uncoated paper margin.

STYLE GUIDE
1. Shape & line
Build the sprig from a thin continuous stem and tapered, needlelike leaf silhouettes, retaining small blue gaps between neighboring leaves. Give the stem and most leaf edges crisp contact-print boundaries so the result reads as an exposure impression.

2. Color & light
Use deep Prussian blue across the exposed field and warm paper-white for the opaque stem and thicker leaf centers. Allow restrained pale cyan within a few thinner leaf areas, preserving a strong light-silhouette-on-blue relationship throughout.

3. Texture & material
Let fine matte paper grain remain visible through the blue, with gentle coating variations and a few watery patches near the field's perimeter. Finish the coated boundary with broad, uneven brush ends while keeping the botanical impression clean and legible.

4. Composition
Keep the lower-left stem base and upper-right leafy tip comfortably inside the coated field. Spread the leaves into a readable branching rhythm, leaving broad blue breathing room on both image sides and a slim paper-white margin around the entire field.

PRIORITY
Preserve the requested identity, count, action, composition and output settings. Apply the style rules within those constraints; a style reference must not replace the subject or layout. Within the style: Prioritize a recognizable rosemary silhouette and the blue-and-paper-white logic of a cyanotype contact print.

AVOID
Avoid green foliage, drawn outline strokes, and dimensional shadows that turn the impression into a photographed plant.

OUTPUT
Create one image in a 4:5 portrait aspect ratio, with no lettering, captions, signatures, or watermark.

SELF-CHECK
Check that one complete sprig remains readable, blue gaps separate the leaves, and the coated paper boundary is visible.
