About Mj Upscale

把候选图推进到可用素材

当一组 Midjourney 图片中已经有合适的方案,Upscale 可以帮助你选出目标图片,并继续完成任务支持的放大处理。它适合封面定稿前查看人物面部、包装轮廓、建筑纹理,也方便把喜欢的单张图片保存下来,交给排版或后期工具使用。

四宫格下方的 U1、U2、U3、U4 对应不同图片。选择正确编号是第一步,但选出单图不一定增加分辨率:较新的 Midjourney 版本会先将图片从网格中分离,再提供进一步放大选项;早期版本的 U 按钮可能直接包含放大。完成后应以输出文件的实际尺寸为准。

放大后会不会改变画面?

可能会。Subtle 更重视保持原有外观,Creative 会加入更多新细节,局部形态也可能改变。若图片用于准确呈现人物或产品,建议先采用变化较少的方式,再逐处检查结果。放大不能保证纠正所有错误,也不能替代对文字和标识的人工核对。

能直接拿来印刷吗?

需要结合输出像素和实际印刷尺寸判断。先下载完整图片,按设计稿需要的裁切范围检查清晰度;如果像素仍不足,再考虑后续处理。单纯把文件缩放到更大的画布,并不会自动得到相同程度的新细节。

Use cases and prompting

找到已完成的源任务,确认想保留的是第几张图片,再提交对应的 U/放大动作。四宫格通常按从左到右、从上到下排列,提交前仍应核对任务提供的编号。

例如要把第三张山间旅馆插画用作折页封面,先选出第三张,检查屋顶线条和树木边缘;若返回后续放大动作,再选择合适方式继续。

保存源图与放大结果,比较画面是否发生不希望的变化,并记录最终文件尺寸。后续需要修改构图时,可回到源任务做变体,避免连续放大偏离原本满意的细节。
