注意：为减少macOS安装包大小，请Mac用户手动安装LUT：去Applications/AlcedoStudio.app/Contents/MacOS（或者在访达打开应用，找到AlcedoStudio，右键查看包内容，然后同样的点进Contents内的MacOS文件夹里面再创建一个LUTs文件夹，然后把Film_LUTs.7z中的cube文件解压进该文件夹

v0.2.3的更新亮点：

• 重构了UI风格与逻辑，配色更柔和，交互更加直观。
• 内置了由各胶片技术手册生成的胶片模拟LUT预设。通过spectral_film_lut将胶片数据手册数字化，然后用光谱物理模型来模拟光线进入胶片、曝光、冲洗、印放的全过程来生成LUT。我在原版基础上增加了对本项目场景参考管线的支持，保留下了负片极为宽广的高光宽容度。
• 支持LOD渲染，哪怕是1.5亿像素的巨型DNG也可被流畅处理，滑块调整丝般顺滑（需8G显存及以上）的同时可放大数毛。

Highlights of the v0.2.3 update:

• Redesigned UI style and logic, with softer color schemes and more intuitive interactions.
• Built-in film simulation LUT presets generated from various film technical manuals. By digitizing film data manuals via spectral_film_lut, we use a spectral physical model to simulate the entire process—from light entering the film to exposure, development, and printing—to generate LUTs. Building on the original version, I’ve added support for the reference pipeline used in this project, while preserving the extremely wide highlight latitude characteristic of negative film. Currently supported films include: Kodak Portra/Ektar/Vision series/TriX/Aerocolor, and Fuji Pro series/Eterna/Superia/C200.
• Supports LOD rendering, allowing even massive 150-megapixel DNG files to be processed smoothly. Slider adjustments are silky smooth (requires 8GB of VRAM or more) while allowing for zooming in to examine fine details.

已知问题

v0.2.3

常见问题

编辑流程

• 部分 RAW 图片解码后可能在高对比度边缘出现彩边（色彩条纹）。这是已知的解码瑕疵，可通过裁剪掉受影响的边缘来规避。
• 如果元数据解析器未正确读取焦距数据，镜头校正将会失败。这个问题经常发生在佳能无反相机上。
• 如果元数据解析器未正确读取相机型号，色温/色调调整将会失败。这个问题可能会发生在一些移动设备上。
• ACES 2.0 不支持 HDR 处理，目前峰值亮度选项是无效的。
• 切换两个波形图时，直方图/波形显示可能无法正确渲染。你可以通过在下方面板中拖动一个滑块来触发重新渲染以解决这个问题。

版本控制

• 切换版本可能会导致 LUT 应用不正确。你可以通过在控制面板中重新选择 LUT 来解决这个问题。
• 版本控制界面过于紧凑，无法显示较长的版本名称。
• "Plain" 版本根本不会将调整重置为默认值。请改用 "Incremental" 版本。

资源管理

• 如果你导入了不受支持的图像（例如，JPEG, TIFF），将无法生成缩略图。你可以从项目中删除这个图像，并在未来版本修复这个问题后重新导入它。
• 如果你从磁盘中删除了一个图像，当前的实现将无法重新链接这个图像，并且所有调整都将丢失。
• 旧版本的项目文件不再受支持。 在 v0.2.3 之前版本中创建的 .puerhproj 文件无法正常加载或行为异常。

其他问题

• 一些文本缺乏中文翻译，即使你将应用设置为其他语言，它们也可能以英文显示。

Windows 问题

• 由于当前实现的技术限制，HDR 预览在 Windows 上不可用。但当你将 DRT 设置为 P3/ST2084 或 Rec.2020/ST2084 时，你仍然可以导出 Ultra HDR 图像。
• 应用不会在 Windows 上自动对屏幕显示进行色彩管理。导出文件会正确嵌入 ICC profile，但应用内预览不受色彩管理约束。请选择与你显示器色彩空间相匹配的输出色彩空间，以确保预览和导出结果的色彩一致。
• 如需编辑 60MP 以上的图片，建议使用 8GB 及以上显存的 GPU。在显存较低的设备上，处理速度可能明显变慢，甚至出现不稳定情况。
• 请将你的 GPU 驱动程序更新到最新版本。最低要求的 GPU 驱动程序版本是 570.xx。较旧的驱动程序将导致崩溃。

macOS 问题

• 我只有一台运行 macOS Tahoe (macOS 26) 的 MacBook Air M4，因此我只能在这个特定的硬件和软件配置上测试应用。该应用为 Apple Silicon 构建。如果你在其他支持 Metal 的 ARM Mac 型号或 macOS 版本上遇到任何问题，请向我报告。
• 应用要求 macOS 13.3 或更高版本。但强烈建议升级至 macOS 26 (Tahoe) 或更高版本以获得最佳体验和完整功能支持。
• 由于我没有加入 Apple Developer Program，应用未签名和未公证。它将被 macOS 的安全措施阻止启动。可能存在解决方法，但这里不会讨论。如果你担心安全问题，建议从源代码构建应用。
• HDR 预览和颜色管理在 macOS 上可用，并且导出图像将被标记为你在 DRT 设置中选择的色彩空间。然而，如果你使用非 sRGB 的色彩空间，UI 颜色将不准确，因为应用不支持 UI 中的颜色管理。

Known Issues

v0.2.3

Common Issues

Pipeline

• Some RAW images may exhibit chromatic fringing (color fringing along high-contrast edges) after decoding. This is a known decode artifact; crop the affected edges as a workaround.
• Lens correction will fail if the focal length data is not properly read by the metadata parser. This issue frequently occurs on Canon mirrorless cameras.
• Color Temp/Tint adjustments will fail if the camera model is not properly read by the metadata parser. This issue may occur on some mobile devices.
• ACES 2.0 does not support HDR processing, where the peak luminance option is currently broken.
• Histogram/Waveform display may not be rendered when switching between two scopes. You can workaround this issue by dragging a slider in the control panel to trigger a re-render.

Versioning

• Version switching may cause LUT to be applied incorrectly. You can solve this by re-selecting the LUT in the control panel.
• The versioning UI is too compact to display long version names.
• The "Plain" version does not reset adjustments to default values at all. Use "Incremental" version instead.

Assets Management

• If you have imported unsupported images, the thumbnail will not be generated. You can delete this image from the project and re-import it after the issue is fixed in future releases.
• If you have delete an image from your disk, the current implementation will not be able to relink the image, and all adjustments will be lost.
• Project files from earlier versions are no longer supported. Opening a .puerhproj file created in a version prior to v0.2.3 may behave unexpectedly or fail to load.

Other Issues

• Some texts miss localization and may appear in English even if you have set the app to another language.

Windows Issues

• The HDR preview is not available on Windows due to a technical limitation in the current implementation. But you can still export Ultra HDR images when you set the DRT to P3/ST2084 or Rec.2020/ST2084.
• The app does not automatically apply color management to the screen display on Windows. Exported files are tagged with the correct ICC profile, but the in-app preview is not color-managed. Select an output color space that matches your monitor to keep preview and exported colors consistent.
• For editing images 60MP or larger, a GPU with 8 GB VRAM or more is recommended. Processing may be significantly slower or unstable on lower-VRAM hardware.
• Please update your GPU drivers to the latest version. The mimimum required GPU driver version is 570.xx. Older drivers will cause crashes.

macOS Issues

• I only have access to a MacBook Air M4 running macOS Tahoe (macOS 26), so I can only test the app on this specific hardware and software configuration. The app is built for Apple Silicon. If you encounter any issues on other ARM Mac models or macOS versions that support Metal, please report them to me and I will try to fix them in future releases.
• The app requires macOS 13.3 or later. However, upgrading to macOS 26 (Tahoe) or later is strongly recommended for the best experience and full feature support.
• Since I haven't enrolled in the Apple Developer Program, the app is NOT signed and notarized. It will be blocked by macOS's safety measures. Workaround may exist but will not be discussed here. It is recommended to build the app from source code if you are concerned about security.
• The HDR preview and color management IS available on macOS, and the export images will be tagged with the color space you choose in the DRT settings. However, the UI color will be inaccurate if you are using a color space other than sRGB, as the app does not support color management in the UI.
• It is recommended to have 16GB of RAM for the app to run smoothly. The app may perform poorly or even crash on machines with less RAM, especially when processing large images.
