How to use Add Symmetry to an Image
- 1. Drop in the source image. Load any image into the input pane. Faces, buildings and landscapes are the usual subjects, since the effect is most striking on things we expect to be nearly symmetric already.
- 2. Choose which half to mirror. The Mirror setting offers Left onto right, Right onto left, Top onto bottom and Bottom onto top. Each option keeps one half untouched and reflects it across the center line, so try both directions on an axis; the two results usually differ dramatically.
- 3. Download the mirrored image. The output keeps the original dimensions with one half replaced by the reflection. Flip between the options in the preview, pick the more interesting composition, and save it.
When to use Add Symmetry to an Image
Add Symmetry to an Image reflects one half of a picture onto the other, producing perfect mirror symmetry across the vertical or horizontal center. It powers the classic two-faces experiment, kaleidoscopic landscape edits, and quick pattern generation, all from a single dropdown choice.
- The symmetrical face experiment. Mirroring the left and then the right half of a portrait produces two surprisingly different people, a demonstration beloved by psychology classes and viral posts alike. Run the same photo through both settings and compare.
- Fake water reflections. Top onto bottom turns a skyline or mountain shot into a glassy lake reflection. It is a fast way to get the mirrored-landscape look without compositing two exposures.
- Seamless decorative patterns. Mirrored halves meet their own reflection cleanly at the center, which makes great raw material for wallpapers, album art and Rorschach-style graphics built from ordinary photos.
- Checking asymmetry in designs. Mirror a logo or icon draft and compare it against the original. Differences that jump out reveal exactly where the artwork drifts off balance, which is hard to see by eye alone.
Examples
