Similarly, some users who frequently produce high-quality images using SD 1.5 experience a decline in the quality of portraits when transitioning to SDXL. However, incorporating certain prompts can significantly enhance the image quality.
同樣,一些經常使用 SD 1.5 生成高品質圖像的使用者在過渡到 SDXL 時會遇到人像品質下降的問題。但是,加入某些提示可以顯著提高圖像品質。

Utilizing Natural Light and Enhancing Background and Proportion

Replacing ambient lighting with sunlight creates a more natural lighting effect, while changing hyper-realistic photographs to ultra realistic photograph further increases realism. Additionally, using a pastel background with pastel bokeh softens the background blur, and exquisite details and textures enhance the overall quality. Adjusting the screen ratio to siena natural ratio further refines the composition.
