BRIDGETOONS - The Comic Book Workhorse
--------------------------------------

Bold lines, punchy colors, comic book aesthetic. Has hires fix enabled
so it handles full body shots well.

Style: American comic book
Triggers: VERY AWA, COMICBOOK STYLE

Why these settings:
  - euler_karras at 38 steps gives clean linework
  - CFG 6.0 balances prompt adherence with natural color
  - 0.3 denoise on hires adds detail without changing composition


CYBERREALISTIC - The Photographer
---------------------------------

Makes images that look like actual photographs. Editorial quality with
realistic skin textures and natural lighting. Keep CFG low or it
over-processes.

Style: Photorealistic/editorial
Triggers: masterpiece, best quality, realistic

Why these settings:
  - dpm++_karras sampler is sharp, good for photo detail
  - Low CFG (4.5) gives natural, not artificial look
  - No hires fix - caused artifacts on Apple Silicon


REALISM
-------

Similar vibe to Cyberrealistic with a slightly different rendering
approach. Very low CFG for maximum natural appearance.

Style: Realistic with artistic touch
Triggers: masterpiece, best quality, realistic

Why these settings:
  - dpm++_karras for sharp detail
  - Very low CFG (4.0) for most natural results
  - 27 steps - this model converges faster than others
  - No hires fix - cleaner without it on Apple Silicon


ARTHEMY - The Western Illustrator
---------------------------------

Western comic/graphic novel style with hatching, flat colors, and bold
composition. Needs the most steps to fully render its detailed linework.
Largest base resolution of the bunch.

Style: Western comics, graphic novel
Triggers: western comics (style), linear hatching, flat color

Why these settings:
  - euler_karras handles the hatching style well
  - 45 steps needed - complex style takes longer to converge
  - Low denoise (0.2) on hires preserves the linework
  - Largest resolution (1024x1344) for detailed illustrations


Full Body Shot Capabilities
---------------------------

Can do full body:
  Bridgetoons - YES (hires fix adds eye detail)
  Arthemy - YES (hires fix + large base resolution)

Stick to cowboy shot or tighter:
  Cyberrealistic - no hires fix, eyes suffer at distance
  Realism - no hires fix, eyes suffer at distance

The issue: without hires fix, full body shots don't have enough pixels
for clean eye rendering. You get asymmetrical or blurry eyes.


Why We Disabled Hires Fix on Some Models
----------------------------------------

On Apple Silicon (M1/M2/M3 Macs), hires fix can cause problems:

  - Impressionist blur patches
  - Scan line artifacts
  - Color banding

Cyberrealistic and Realism looked better WITHOUT hires fix on Mac.
Bridgetoons and Arthemy handle it well.

If you're on NVIDIA hardware, you might be able to enable hires fix
on all models. Test and see.
