+# Photography, Color, and Print
+
+## Color Profiles
+
+| Profile | Use For |
+|---------|---------|
+| `sRGB` | Web delivery, most marketplaces, social |
+| `Adobe RGB` | Print workflows with wider gamut |
+| `ProPhoto RGB` | High-end RAW editing and master files |
+
+- Browsers and many upload pipelines effectively expect sRGB.
+- Wide-gamut files exported for the web without conversion often look washed out or inconsistent.
+- Embed the ICC profile when the destination respects color management.
+
+## RAW and Non-Destructive Editing
+
+- RAW files are source negatives; do not overwrite them.
+- Keep edits in sidecars, catalogs, layered masters, or non-destructive instructions when possible.
+- White balance corrections are safer in RAW than in JPEG.
+- Different RAW converters can produce visibly different output from the same file.
+- Keep at least one master export suitable for future edits before creating flattened delivery versions.
+- Noise reduction, clarity, and sharpening should be balanced for the final destination; settings that feel dramatic on screen often print badly.
+
+## Metadata and EXIF
+
+Preserve when needed:
+- Copyright and author data
+- Editorial provenance
+- Archive or legal context
+
+Strip when appropriate:
+- Public web publishing
+- Sensitive location data
+- Irrelevant camera metadata on lightweight delivery assets
+
+GPS warning:
+- Strip GPS before public delivery for homes, private locations, or sensitive subjects.
+
+## Print Export Rules
+
+| Setting | Web | Print |
+|--------|-----|-------|
+| Color space | sRGB | Adobe RGB or printer profile |
+| Resolution | 72-150 PPI guidance | 300 PPI typical |
+| Format | WebP/JPEG/PNG | TIFF or high-quality JPEG |
+| Metadata | Minimal | Preserve if needed |
+
+- Print work must care about physical size, bleed, sharpening target, and final output process.
+- A web export that looks good on screen is not automatically print-safe.
+- Ask whether the destination printer, lab, or publication has its own profile and export requirements before assuming a generic print preset.
+- Soft-proofing or at least checking for gamut clipping is worth it when brand colors or skin tones must survive print.
+
+## Retouching Traps
+
+- Over-smoothing skin or texture until the file looks synthetic.
+- Aggressive sharpening halos that only become obvious in print.
+- Cropping too tightly and leaving no safe room for print trims or editorial layouts.
+
+## Quality Control
+
+Before delivery:
+
+```
+□ Orientation fixed
+□ ICC profile intentional
+□ No clipped highlights or blocked shadows
+□ No obvious halos or oversharpening
+□ Dust spots or sensor marks checked
+□ Metadata decision made on purpose
+```
