Basic Usage

# Basic processing with defaults
ai-pp3 input.dng -o output.jpg

# PP3-only mode with custom prompt
ai-pp3 input.dng --pp3-only -p "Unleash the full potential of RAW image pp3 settings with a dramatic flair. Elevate your creative precision by providing:

1. ANALYSIS: A profound exploration into the image's essence, identifying its strengths and areas for transformation.
2. PLAN: Set ambitious goals for adjustments and articulate a vivid creative vision that transcends ordinary imagery.
3. CHANGES: Deliver precise SEARCH/REPLACE blocks to breathe life into the envisioned transformation.

RULES:
- Respect the original structure & headers as the foundation upon which to build your masterpiece.
- Proceed thoughtfully, modifying only those values necessary to achieve the desired dramatic effect.
- Maintain the document's integrity by never adding or removing sections.
