真实手工蓝晒日晒印相风格

Transform the attached photograph into a single, authentic cyanotype sun print, photographed as a physical artwork. Vertical 4:5 composition.

THE SHEET

A handmade cyanotype on thick cotton rag paper, lying on a plain, pale surface in soft natural daylight. The image fills most of the sheet, leaving visible white margins on all four sides. Keep the entire sheet inside the frame, with at least three edges clearly visible and one edge preferably showing a fibrous tear. The paper has subtle cockling from washing and drying, with realistic surface texture and a soft shadow along one side.

HAND-BRUSHED COATING

The photosensitive coating is applied by hand. Blue boundaries are naturally irregular, with visible brushstroke endings, small uncoated patches, uneven edges, and a few stray blue flecks on the white margins. Avoid perfectly straight, mechanical borders on all four sides.

CYANOTYPE TONES

Use only authentic cyanotype colours:

- Shadows: Deep Prussian blue.
- Midtones: Pale to medium cyan.
- Highlights: Completely bare, raw white paper with no blue pigment.

Maintain strong contrast and abrupt transitions between blue and white where appropriate, as in a traditional contact print. Fine paper fibres should remain visible through the blue. No grey, black, sepia, or additional colours. The result must look like a chemically produced cyanotype, not a blue filter over a photograph.

PRESERVE THE ORIGINAL IMAGE

Use the attached photograph as the sole source. Preserve the exact number, identity, position, proportions, silhouettes, poses, and arrangement of all subjects. Do not add, remove, duplicate, or rearrange people, animals, vehicles, or environmental details.

Translate the original photograph into cyanotype tones only: bright areas become bare paper white, midtones become cyan, and dark areas become deep Prussian blue. Preserve the original composition and recognisable facial and body shapes.

PHYSICAL PRESENTATION

Photograph the finished print as a real object resting on a plain, pale surface. Use soft directional daylight, realistic paper fibres, subtle shadows, and natural surface imperfections. Keep the entire sheet visible within the vertical 4:5 frame.

STRICT NEGATIVE CONSTRAINTS

- No text, letters, numbers, signatures, logos, stamps, or watermarks.
- No additional or missing subjects.
- No grids, graph lines, measuring scales, or blueprint-style graphics.
- No blue tint in the brightest highlights; they must be raw paper white.
- No extra colours, decorative effects, or artificial distressing.
- No hands, clips, frames, tools, props, or additional sheets.
- No cropping of the sheet or digitally flat presentation.

PRIORITIES

If every detail cannot be achieved simultaneously, prioritise preserving the exact original subjects and making the brightest highlights completely paper white. Next, maintain realistic physical paper texture and visible sheet edges. If necessary, simplify the brushed margins to one irregular edge and leave the other three edges cleanly cut.

Final result: A realistic, handmade cyanotype sun print with deep Prussian-blue shadows, cyan midtones, pure white paper highlights, organic brushed edges, and authentic cotton-rag texture, photographed as a physical object in soft daylight. Vertical 4:5 aspect ratio.

将附件中的照片转化为一张单一的、真实的蓝晒法日晒印相，并作为一件实体艺术品进行拍摄。垂直 4:5 构图。

纸张

一张在厚棉浆纸上制作的手工蓝晒图，平放在柔和自然日光下的平坦、浅色表面上。图像占据了纸张的大部分，在所有四个侧面留有可见的白色边距。将整个纸张保持在框架内，至少三个边缘清晰可见，其中一个边缘最好显示出纤维状撕裂。纸张因洗涤和干燥而有细微的起皱，具有真实的表面纹理，并在一侧带有柔和的阴影。

手刷涂层

感光涂层是手工涂抹的。蓝色边界自然不规则，带有可见的刷痕末端、小的未涂层斑块、不均匀的边缘，以及白色边距上的一些零散蓝色斑点。避免在所有四个侧面出现完美的直线、机械化边界。

蓝晒色调

仅使用真实的蓝晒颜色：

- 阴影：深普鲁士蓝。
- 中间调：浅至中度青色。
- 高光：完全裸露、原始的白纸，没有蓝色颜料。

在适当的情况下，保持蓝色和白色之间强烈的对比和突然的过渡，就像传统的接触印相一样。精细的纸张纤维应保持通过蓝色可见。没有灰色、黑色、棕褐色或额外的颜色。结果必须看起来像化学产生的蓝晒图，而不是照片上的蓝色滤镜。

保留原始图像

使用附件照片作为唯一来源。保留所有主体的确切数量、身份、位置、比例、剪影、姿势和安排。不要添加、删除、重复或重新排列人物、动物、车辆或环境细节。

仅将原始照片转化为蓝晒色调：明亮区域变为裸露的白纸，中间调变为青色，黑暗区域变为深普鲁士蓝。保留原始构图和可识别的面部及身体形状。

物理呈现

将完成的印相作为放置在平坦、浅色表面上的真实物体进行拍摄。使用柔和的有方向性的日光、真实的纸张纤维、细微的阴影和自然的表面瑕疵。保持整张纸在垂直 4:5 的框架内可见。

严格的负面约束

- 没有文字、字母、数字、签名、徽标、印章或水印。
- 没有增加或缺失的主体。
- 没有网格、坐标线、测量标尺或蓝图风格的图形。
- 在最亮的高光部分没有蓝色调；它们必须是原始的白纸。
- 没有额外的颜色、装饰效果或人工做旧。
- 没有手、夹子、框架、工具、道具或额外的纸张。
- 没有对纸张的裁剪或数字平面化呈现。

优先级

如果不能同时实现每一个细节，请优先保留确切的原始主体，并使最亮的高光部分完全呈现纸张白。其次，保持真实的物理纸张纹理和可见的纸张边缘。如果有必要，将刷过的边缘简化为一个不规则边缘，并让其他三个边缘保持干净的切割。

最终结果：一张真实的、手工制作的蓝晒法日晒印相，具有深普鲁士蓝阴影、青色中间调、纯白纸张高光、有机的手刷边缘和真实的棉浆纹理，并作为实体物体在柔和日光下拍摄。垂直 4:5 的宽高比。
