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.
