## Total Visibility
* Introduction to mastering image fitting and display techniques to preserve visual data.

## The Cropping Dilemma
* 'Cover' fitting often removes visual narrative by slicing edges.
* 'Contain' methods are prioritized to keep the entire frame intact.

## Why Full Visibility Matters
* Context: Edge details provide essential storyteller context.
* Composition: Respects the original framing of the photographer.
* Integrity: Prevents misleading size or scale representations.

## Common Aspect Ratios vs. Screen Space
* Analysis of screen coverage on a 1920x1080 display:
  * 16:9: 100% coverage (Fit)
  * 4:3: 75% coverage (Pillarbox)
  * 1:1: 56% coverage (Pillarbox)
  * 9:16: 31% coverage (Heavy Pillarbox)

## Letterboxing Technique
* Utilizes black or neutral padding to preserve aspect ratio without distortion.
* Gold standard for avoiding data loss.

## Implementation Strategies
* CSS Object-Fit: Use `object-fit: contain` for web-based slides.
* Background Matching: Match background color to image edges to reduce layout shift contrast.
* Viewport Units: Use `max-height: 90vh` to prevent overlap with UI elements.

## User Preference on Detail
* Research shows 82% of audiences in technical/artistic contexts prefer 'Full Containment' over 'Cropped Fill' (18%).

## Final Principle
* Design Principle 101: "A picture is worth a thousand words, but only if you can read the whole sentence."
* Embracing containment ensures no hidden corners or lost data.
