Lunar HDR Studio 0.4.0

Lunar HDR Studio 0.4.0 improves Mineral Moon processing and makes the project easier to clone and run.

• English README, with a linked Slovak translation and a real photographic example processed from lunar FITS captures.
• MIT license for the original project code, included in the standalone apps.
• Portable source launchers for macOS, Windows and Linux. They find Python 3.11–3.14, set up a local environment, and reuse matching dependencies without calling pip on every launch. --check verifies setup without opening the app.
• Mineral Moon selectively amplifies recorded surface color differences with luminance and gamut protection. The preset keeps exposure at 0 EV and adds no sky black point; glow remains controlled by your captures and exposure adjustments.
• Color and detail still depend on the source captures. The README example retains the actual warm/teal variations in its FITS inputs; the app does not manufacture the colors or resolution of a separate reference photograph.
• New launcher and mineral-color regression tests, plus an automatic startup check of each packaged application and its bundled preview.

Clone and run instructions are in the English README. Standalone ZIPs need no Python installation: extract the package for your platform and open LunarHDR.

macOS packages are ad-hoc signed without Apple notarization. Windows packages do not have a publisher signature. Linux needs the Qt runtime libraries listed in the README. Dependency licenses and photographic-image rights remain separate from the MIT code license.

Verified in GitHub Actions run 36310250413: 113 tests on macOS/Linux and 112 on Windows, with successful packaged startup on all four targets. A fresh anonymous clone, first-run installation and app startup also passed on macOS with Python 3.14.2.

Lunar HDR Studio 0.3.0

First public release of Lunar HDR Studio. The desktop interface is in Slovak and all image processing runs locally.

• Fixed PNG export from desktop launches: the save dialog now starts in Pictures instead of attempting to write /Lunar-HDR.png.
• Load two or more lunar exposures, including FITS, FITS.gz, compressed FITS image HDUs, TIFF, PNG and JPEG.
• Align lunar disks and surface details, then create HDR or exposure fusion with editable Mineral Moon controls.
• Keep original background stars, suppress stars, or add an explicitly synthetic star effect.
• Crop by dragging in the preview and add a custom text signature. PNG/JPEG/16-bit TIFF include these edits; linear Radiance HDR preserves the full unedited radiance image.
• Public demo artwork is procedural. User photographs are not included.

92 automated tests passed on macOS Apple Silicon, macOS Intel, Windows and Linux. All four standalone builds passed in the verified GitHub Actions run. PNG export with crop and signature was also verified interactively in the standalone macOS app.

Download the ZIP for your operating system, extract it, and launch LunarHDR. Python is not required for the standalone builds. macOS builds are ad-hoc signed, without Apple notarization; Windows builds do not have a publisher signature. Linux needs a desktop session and Qt system libraries described in the README.

Source launch instructions, format limitations and validation details are in the repository README and VALIDATION.md.
