Open 100x

Extreme 100x hybrid zoom camera with local image processing.
Open 100x is an Android camera app built to give more phones access to extreme 100x zoom-style shooting, even when the stock camera app does not expose that kind of range.

It combines native camera zoom with digital crop to reach up to 100x, and adds controls designed for long-range mobile photography. The app includes stability feedback, histogram tools, grid modes, zoom presets, flashlight support, crop nudging, and local post-processing for extreme zoom captures.

Open 100x runs fully on-device. It uses traditional, non-AI image processing only, with no cloud processing and no external APIs.

Current beta notes:

* Android app package: com.example.zoomhundred
* Up to 100x zoom through native camera zoom plus digital crop
* Local denoising, smoothing, sharpening, contrast/detail recovery, and crop upscaling
* Pro-style overlays and anti-shake feedback for high-zoom shooting
* Device behavior may vary because camera hardware and third-party lens access differ across Android devices
