Here are some key tips I've learned after months of running SD.
- Prompt: Keywords like 'photorealistic, 8k, detailed skin texture' are essential.
- Negative Prompt: Adding 'cartoon, anime, deformed hands' makes the character look natural.
- Checkpoint: Realistic Vision V4.0 is the best.
- VAE: Switching to kl-f8-anime2 instead of the default improves color tones.
- Sampler: DPM++ 2M Karras offers the best balance of speed and quality.
Final tip: Use ControlNet to set the pose and Img2Img to refine details—the result will look like a real photo.
