引用链接与cref的区别

有时候比较随意，又比较着急，会随机的引用链接或者--cref，会影响生成图的走向，同时也会忽略很多看不到却一直会重复的问题，做了一个测试，对比区别。

以一张古风男子测试，把图放到Midjourney里描述，得到描述词4个，选其中一个，然后图链接+描述词🆚 图链接+自己调整后的提示词，以不同的方式引用进行对比。

在画风和质感上，描述词给出的提示词效果更好。

在人物的一致性上，引用人物参考会更还原，而且在后期刷新和选不同版本时也更稳定。直接作为引用链接，在刷新图时变化更大更有创意。

综合来说这次的尝试3效果理想一点（上图左三，引用人物参考 --cref 图链接 + 描述提示词）

提示词也很关键，会影响方方面面，比如画风、光线。

一般图片如果不是特别高清的话，引用图片时，多少都会有一些模糊，可以多刷几遍，有时候会变清晰。有时候不会变清晰，可以换一张图尝试，或者换一个模式，先生成摄影风格，或者3D风格。

以下是过程细节，可以跳过。本文中的图片，可供学习与分享以及二次创作。

刚刚提到的注意点，在这个步骤会出现，重复一遍。

这时候画质时清晰的，服装感觉大致都在，人物和发型并没有保持一致

画质、服装、人物和发型感觉大致都在，平面了一点，可能是引用的画风比较平面，暖色调的原因，停止探索。
