              </p>
              <p>漫画图片发黄时，先判断是扫描或拍摄带来的黄色偏色，还是纸张本身已经变黄。前者通常可通过白平衡、色阶或曲线校正；后者只能减轻底色，不能凭空恢复被纸张老化遮住的线条和细节。处理时建议保留原图副本，再按“校正底色—保护线稿—检查细节—按用途导出”的顺序调整，避免把纸面调成刺眼的纯白。</p>

<h2>先判断黄调来自哪里</h2>
<p>如果整页背景、对白框和浅色区域都呈现相近的黄色，黑色线稿仍清楚，多半是扫描仪或手机拍摄的白平衡偏暖。若页面边缘比中心更黄，或有斑点、污渍和明显色差，通常还叠加了纸张老化、光照不均等问题。彩色漫画则要多看肤色、天空和服装等区域：整体偏黄可以校色，只有纸边发黄时，更适合局部处理。</p>
<p>先观察原图的黑线是否已经发灰、浅色区域是否仍有纹理。如果一开始就把亮度大幅拉高，纸色看似变白，细线、网点和淡色效果线也可能一起消失。对有复古暖色设计的漫画，不宜把所有暖色都当作错误偏色。</p>

<h2>通用去黄流程：从轻度校色开始</h2>
<ol>
  <li><strong>保留原图并检查方向。</strong>复制一份作为工作文件，确认页面没有歪斜、阴影或明显反光。拍摄图若左右两侧亮度不同，先做透视和明暗校正，再处理色调。</li>
  <li><strong>调整白平衡或色温。</strong>在图像编辑软件中找到“白平衡”“色温”或“色彩平衡”功能，逐步降低偏暖程度。可用对白框、未印字的页边等接近纸白的区域作为参照，但不要直接以最亮的反光点取样。</li>
  <li><strong>用色阶或曲线控制纸色。</strong>轻微提高中间调亮度，让纸面变浅；同时观察黑色线条是否仍然浓实。若软件支持按颜色通道调整，可少量降低黄、红分量，避免整体亮度过度抬高。每次改动后放大查看细线和网点。</li>
  <li><strong>必要时局部处理。</strong>仅边缘、折痕或某块背景发黄时，用蒙版、选区或局部画笔限制调整范围。边缘要柔和过渡，别让处理区域留下明显白边。污渍和破损需要修复工具逐处处理，单纯去黄不会自动补回缺失画面。</li>
  <li><strong>对照原图收尾。</strong>以页面整体缩放检查阅读效果，再放大查看对白框、细线和网点。若纸白过亮、黑线发灰或彩色区域变得不自然，应降低调整强度，而不是继续推高亮度和对比度。</li>
</ol>
<p>黑白漫画可以优先尝试轻度去色或灰度处理，让纸底更中性、线条更易读；但若原图有彩色网点、彩色封面或特殊色块，直接转成灰度会丢失信息。彩色漫画应以整体色彩自然为目标，避免只顾把背景调白而改变人物肤色和画面氛围。</p>

<h2>按漫画类型和阅读场景调整</h2>
<p><strong>扫描的黑白内页：</strong>先校正整页偏色，再微调亮度和对比度。线稿较淡时，可谨慎加深暗部；若原图含细密网点，不要使用过强的锐化或降噪，以免网点糊成色块。</p>
<p><strong>手机拍摄的纸质漫画：</strong>除了色温，还要检查页面阴影、透视和反光。均匀照明、相机与页面尽量平行，往往比后期大幅拉色阶更能保留细节。遇到光斑遮住文字或线条时，校色只能改善周围色调，无法还原被反光覆盖的内容。</p>
<p><strong>已有电子文件：</strong>如果图像本身只是色温偏暖，可直接从色彩校正入手；如果是低分辨率或压缩严重，去黄不会提升原始细节。不要把插值放大的尺寸误认为清晰度增加，重要线稿最好保留未经处理的版本。</p>

<h2>导出时保留画面质量</h2>
<p>继续编辑或归档，可保留原始格式，或导出为 PNG、TIFF 等较少受重复压缩影响的格式；用于普通屏幕阅读时，JPEG 也较方便，但应避免反复打开、修改并另存造成画质损失。导出前检查图片方向、裁切范围和文字边缘。屏幕使用主要看像素尺寸是否满足实际显示需求；用于印刷时，再结合成品尺寸设置分辨率。无论用途是什么，建议同时保存原图和校色版本，便于日后重新调整。</p>
<p>去黄的合理目标是让页面底色更中性、漫画内容更清楚，而不是把旧漫画改成没有纸感的纯白图。偏色越轻，越适合采用小幅调整；纸张严重变色、褪色或已有信息缺失时，应接受可恢复程度有限，避免用过度处理换取表面上的亮白。</p>
