手写签名即时成像照

使用上传的参考图作为主体参考。
生成参考图中同一角色或主体的签名即时成像照。保留参考图中主体可识别的视觉特征、发型、脸部结构、身体比例、服装设计、配饰、可见标记、主要道具、色彩分布以及姿态关系。
最终图像须为竖版2:3比例。
使其呈现为实体艺人周边的即时相片效果：直接的相机闪光灯、柔焦、低分辨率即时胶片质感、压缩的对比度、轻微的运动模糊、有光泽的照片表面、灰尘斑点、细小划痕、轻微的色偏、暗角衰减，以及厚实的白色即时相框。
主体居中且占据主导。保留参考图的原始场景类型，但使背景略微模糊、细节减少。保留参考图原有的光线氛围，同时添加细微的即时相机闪光效果。
在图像底部创建一条大的白色边框，约占整张图像高度的24–30%。该底部边框主要用于手写文字，但若手写文字较长，可自然向上延伸到照片区域。若文字延伸进照片区域，可与主体、服装、道具或背景重叠，但不得完全遮挡主体的面部。
添加三个独立的手写文字元素：
1. COMMENT_1:
将“メインコメント”写成最大的手写信息，主要横跨底部白色边框。写得大而有活力、突出醒目。若文字较长，可略微延伸进照片区域。使用“メインコメントの色”马克笔墨水书写。
2. ARTIST_NAME:
在COMMENT_1附近书写“アーティストネーム”，比COMMENT_1略小，约为COMMENT_1尺寸的70–85%。使其看起来像快速的艺人签名，比普通手写更具强烈的风格化。使用“アーティストネームの色”马克笔墨水书写。

3. COMMENT_2:
在图像上方书写“画面上部コメント”，位于照片区域而非底部边框。将其放在靠近上边缘或上角的位置，带有随意的手写倾斜角度。它可与背景或主体的外缘重叠，但不得完全遮住面部。使用“画面上部コメントの色”马克笔墨水书写。

4. 活动文字"天 ROCK FEST THE COUNTDOWN 26-27"：白色边框左下角的一行小字。使用清晰、易读、非风格化的无衬线块状字体。颜色：黑色。

所有手写文字都要高度风格化且富有活力：快速连笔、长而流畅的收尾、锐利的转角变化、圈环状草体字形、墨水压力不均、字形紧凑、字符部分重叠、轻微斜向移动以及不规则的字距。日文文字使用松散的草书风格毛笔手写，笔画连贯且有省略。英文文字使用松散的草体马克笔手写。其他语言使用连贯、倾斜的手写笔画，并带有变化的笔压。
手写内容必须看起来是用彩色马克笔直接写在即时照片表面和白色边框上的真实书写，而非数字叠加。包含不完整的墨迹边缘、轻微晕染、笔压变化和自然的手部运动。
若未指定颜色占位符，默认使用黑色马克笔墨水。
避免打字字体、干净的数字字幕、完美的排版、印刷标志、水印、多余人物、无关的服装变化、无关的背景替换、过度锐利，以及完全清晰可读的块状字母。

Use the uploaded reference image as the subject reference.
Generate a signed instant-film snapshot of the same character or subject shown in the reference image. Preserve the subject’s recognizable visual features, hairstyle, face structure, body proportions, outfit design, accessories, visible markings, main prop, color placement, and pose relationship from the reference image.
The final image must be a vertical 2:3 aspect ratio image.
Make it appear as a physical artist merchandise instant photo: direct camera flash, soft focus, low-resolution instant film texture, compressed contrast, slight motion softness, glossy photo surface, dust specks, small scratches, mild color shift, dark edge falloff, and a thick white instant-photo frame.
Keep the subject centered and dominant. Keep the original scene type from the reference image, but make the background slightly blurred and lower in detail. Preserve the original lighting mood while adding a subtle instant-camera flash effect.
Create a large bottom white border, occupying about 24–30% of the full image height. Use this bottom border mainly for handwritten text, but allow long handwritten text to naturally extend upward into the photo area if needed. If text extends into the photo area, it may overlap the subject, clothing, prop, or background, but it should not completely cover the subject’s face.
Add three separate handwritten text elements:
1. COMMENT_1:
Write “メインコメント” as the largest handwritten message, mainly across the bottom white border. Make it large, energetic, and dominant. It may extend slightly into the photo area if the text is long. Use “メインコメントの色” marker ink.
2. ARTIST_NAME:
Write “アーティストネーム” near COMMENT_1, slightly smaller than COMMENT_1, about 70–85% of the COMMENT_1 size. Make it look like a fast artist autograph, with heavier stylization than ordinary handwriting. Use “アーティストネームの色” marker ink.

3. COMMENT_2:
Write “画面上部コメント” in the upper part of the image, over the photo area rather than the bottom border. Place it near the top edge or upper corner, with a casual handwritten angle. It may overlap the background or the outer edge of the subject, but it should not fully hide the face. Use “画面上部コメントの色” marker ink.

4. Event text "天 ROCK FEST THE COUNTDOWN 26-27": A single, small line in the bottom-left corner of the white border. Uses a clear, legible, non-stylized block typeface. Color: black.

For all handwritten text, make the letters heavily stylized and energetic: fast connected strokes, long sweeping tails, sharp angle changes, looped cursive forms, uneven ink pressure, compressed characters, partial character overlap, slight diagonal movement, and irregular spacing. For Japanese text, use loose sosho-style brush handwriting with connected, abbreviated strokes. For English text, use loose cursive marker handwriting. For other languages, use connected, slanted handwritten strokes with varied pressure.
The handwriting must look physically written with colored marker ink directly on the instant photo surface and white border, not digitally overlaid. Include imperfect ink edges, slight smudging, pressure variation, and natural hand movement.
If a color placeholder is not specified, use black marker ink as the default.
Avoid typed fonts, clean digital captions, perfect typography, printed logos, watermarks, extra people, unrelated clothing changes, unrelated background replacement, excessive sharpness, and perfectly readable block letters.
