Vertical flips invert gravity cues: sky, ground, and shadows reread
`flip-vertical` helps when scanners or exporters hand you an upside-down JPEG, when you need to swap reflection versus real subject emphasis, or when a deck import ignores orientation. Unlike rotation, vertical flip keeps pixel dimensions but swaps sky and ground, which can make shadows climb upward and buildings feel physically wrong. Water reflections become ambiguous about which side is real. Portrait hair, lapels, and lav mics follow gravity—after a vertical flip they can look uncanny. Album batches that mix auto-rotate with manual vertical flips can yield half upright and half inverted galleries. Always reconcile EXIF orientation first: many viewers already rotate, and a second flip doubles the error. Decide whether the story should privilege reflection or reality before exporting.
Vertical flip workflow
- On `flip-vertical`, confirm EXIF orientation was applied before flipping again.
- Check sky, horizon, and shadow direction for physical plausibility.
- For reflection-led art, pick which side anchors the narrative before export.
