采样器的作用
采样器是Flux文生图中用于从模型中生成图像的算法。不同的采样器会影响图像的生成速度、细节丰富度和随机性。选择合适的采样器可以帮助你在速度和质量之间找到最佳平衡。
2. 常见采样器及其特点
- Euler:生成速度快,适用于快速生成图像,但细节可能不够精细。
- DPM2:生成速度适中,能够提供较好的图像质量。
- HeunPP2:生成细节丰富的图像,但速度较慢。
- Uni_PC:平衡速度和质量,是大多数情况下的推荐选择。
- DEIS:能够很好地把握光影明暗,适合需要高对比度的场景。
- 等等
3. 采样器与调度器的组合测试
以如下提示词为例子
soft_style,The image depicts a young woman standing prominently in the foreground with a bright,clear blue sky above her. She wears a vibrant yellow outfit which matches the similarly colored sports car partially visible behind her. The viewpoint is from a low angle,emphasizing her confident stance and the dynamic outlines of the car. Her expression is calm and composed,portraying a sense of cool confidence. The lighting is bright,indicating a sunny day,which casts sharp shadows and enhances the vividness of the scene's colors. This composition seems to celebrate boldness and style,utilizing color coordination and perspective to create a striking visual impact.,
测试图如下,部分组合差距较为不明显,注意观察。
结论
效果好的搭配如下
- uni_pc + beta
- deis + beta
- deis + simple
- ipndm + beta
