One Open Book · Gutter-Directed Page Curvature

An illustration that gives an open book depth through pages curving into the gutter and curved bands of shading.

Style guide

One Open Book · Gutter-Directed Page Curvature

Shape & line
Draw each facing page as a gently bowed surface that rises away from the central gutter before settling toward its outer edge. Curve the upper and lower page boundaries together so they describe the same bend, and let the visible page stacks follow those curves.
Color & light
Use warm ivory pages and a muted brick-red cover. Place the light at image upper left: keep the image-left page broadly light, lay a wider soft shadow along the image-right side of the gutter, and bend its edge with the page surface rather than drawing a straight dark stripe.
Texture & material
Render matte paper with restrained gouache-like fills and a faint paper grain. Suggest the page stacks with a few fine, separated curved lines beneath the outer edges; keep the facing pages mostly smooth so surface texture does not obscure their curvature.
Composition
Center the book against a pale neutral background and keep its full silhouette visible. Show a narrow rim of the red cover beneath the pages and a soft cast shadow extending toward image lower right, darkest directly under the book where it meets the surface.

Priority
Make the curved page surfaces and recessed gutter readable before adding paper detail.

What to avoid & what to check

Avoid flat rectangular pages, a uniformly black gutter, and dense page-edge striping.

Check that page contours and shading describe the same bend into the central gutter.

Exact prompt for this example
SUBJECT
One open, unprinted hardcover book resting on a flat surface, with two facing pages joined at a recessed central gutter and thin page stacks visible beneath their outer edges.

COMPOSITION
Use an elevated three-quarter view, with the book's lower edge facing the viewer and its gutter running from lower center toward upper center. Show both facing pages clearly, with ample empty space around the entire book.

STYLE GUIDE
1. Shape & line
Draw each facing page as a gently bowed surface that rises away from the central gutter before settling toward its outer edge. Curve the upper and lower page boundaries together so they describe the same bend, and let the visible page stacks follow those curves.

2. Color & light
Use warm ivory pages and a muted brick-red cover. Place the light at image upper left: keep the image-left page broadly light, lay a wider soft shadow along the image-right side of the gutter, and bend its edge with the page surface rather than drawing a straight dark stripe.

3. Texture & material
Render matte paper with restrained gouache-like fills and a faint paper grain. Suggest the page stacks with a few fine, separated curved lines beneath the outer edges; keep the facing pages mostly smooth so surface texture does not obscure their curvature.

4. Composition
Center the book against a pale neutral background and keep its full silhouette visible. Show a narrow rim of the red cover beneath the pages and a soft cast shadow extending toward image lower right, darkest directly under the book where it meets the surface.

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: Make the curved page surfaces and recessed gutter readable before adding paper detail.

AVOID
Avoid flat rectangular pages, a uniformly black gutter, and dense page-edge striping.

OUTPUT
Create one square illustration with no lettering, numbers, captions, logos, or watermark.

SELF-CHECK
Check that page contours and shading describe the same bend into the central gutter.
