UNDERSTANDING FRAMING
Framing = how much of the person shows up. This matters a lot when you don't have hires fix.
Framing Options
+-------------+----------------------+-------------+
| Framing | What You See | Eye Quality |
+-------------+----------------------+-------------+
| close-up | Face only | Excellent |
| bust | Head and shoulders | Excellent |
| upper body | Head to mid-torso | Very good |
| cowboy shot | Head to mid-thigh | Good |
| thigh up | Head to thighs | Acceptable |
| full body | Everything | Needs hires |
+-------------+----------------------+-------------+
The Eye Problem
Here's the deal: SDXL struggles with eyes when they're tiny.
Full body at 832x1216? The face is maybe 5-10% of the image. Not enough pixels to get clean, symmetrical eyes.
Hires fix normally solves this - upscale 2x, run a detail pass. But on Apple Silicon, that detail pass often trashes the image instead of helping it.
RULE OF THUMB: No hires fix? Stay at cowboy shot or tighter.
Resolution by Model
+----------------+-----------------+-----------------+
| Model | Base Resolution | With Hires (2x) |
+----------------+-----------------+-----------------+
| Bridgetoons | 672x1200 | 1344x2400 |
| Cyberrealistic | 832x1216 | disabled |
| Realism | 832x1216 | disabled |
| Arthemy | 1024x1344 | disabled |
+----------------+-----------------+-----------------+
Arthemy's got the biggest base resolution, which helps make up for not having hires fix.
