How It Works:
The app uses a software simulation of fisheye lens distortion based on image bump distortion filters. It applies these effects live to the camera feed and to photos or videos captured or imported. The distortion strength and lens style presets allow users to customize the look from subtle wide-angle barrel effects to dramatic fisheye bulges or pincushion inward pinches. Color grading and vignette effects enhance the artistic style.

Tips:
- Use the timer for hands-free selfies or group shots.
- Experiment with different lens presets and strength settings for creative compositions.
- Enable Pro features for full manual control and video recording.
- Use grid overlays and horizon line guides for balanced framing.
