GR Mod 0.8.9

新功能(GR IV / GR IV HDF)

  • JPG 的 HDR 增益图。 在影像控制的附加功能里打开「HDR 增益图」,生成的固件会给每张 JPG 加一张增益图(从照片本身算出,高光最多提亮 2 档)。
    • 在支持 HDR 的屏幕上(iPhone 相册、安卓 14 以上的 Google 相册、电脑上的 Chrome 等),高光会更亮、更通透;普通看图软件里和原来的 JPG 一样。
    • 文件同时写 Ultra HDR 和 ISO 21496-1 两种格式;相机原来的文件头和图像数据一个字节都不改,相机回放、放大、旋转、保护都正常。
    • 相机拍摄菜单第 4 页「色彩空间」下面多了一行「HDR」,可以随时开 / 关(默认开)。关的时候不做任何额外计算,写出的 JPG 和原厂一样。机内 RAW 显影导出也跟着这个开关。
    • 增益图是从成片推算的:已经过曝的地方会更亮,但找不回细节。
  • ADJ 拨杆最多 8 个栏目。 在影像控制的附加功能里选择 5 / 6 / 7 / 8 个。
    • 设定 1–8 都在相机 自定义设置 ›「ADJ模式设定」里,一屏显示 6 行,往下会滚动。
    • 拨杆界面一行排开所有栏目;新加的栏目刷完后是空的,设好以后才会出现。
    • 多出来的栏目存在原厂不用的字节里,刷回原厂或旧版固件不受影响。

已在 GR IV HDF(固件 1.20)上实测:测试固件 072(ADJ)、074(HDR)、075(两者一起,含菜单开关)。固件 1.11 上同样可用,但没有在 1.11 的相机上实测。

注意

  • 想用这两个功能的话,更新软件后请在附加功能里打开,重新生成固件并写入相机。
  • GR III / GR IIIx 不受影响。

Mac 版

GRMod-0.8.9-mac.zip:Intel 芯片 macOS 10.13 及以上,Apple 芯片 macOS 11 及以上。解压后把 GR Mod 拖到「应用程序」;第一次打开如果被系统拦下,在「系统设置 → 隐私与安全性」里点「仍要打开」。


English

New (GR IV / GR IV HDF)

  • HDR gain map in JPEGs. Turn on "HDR gain map" in Image Control's extra features and every JPEG gets a gain map made from the picture itself (highlights up to 2 stops brighter).
    • On HDR screens (iPhone Photos, Google Photos on Android 14+, Chrome on a computer) the highlights are brighter; other viewers show the same JPEG as before.
    • Both Ultra HDR and ISO 21496-1 metadata are written; the camera's own header and image data are unchanged byte for byte, and playback, zoom, rotate and protect work as before.
    • A new "HDR" line on page 4 of the still shooting menu, after Color Space, turns it on or off (on by default). Off costs nothing and writes the factory JPEG. In-camera RAW development follows the same switch.
    • The gain map is worked out from the finished picture: clipped highlights get brighter but no detail comes back.
  • Up to 8 ADJ lever items. Choose 5, 6, 7 or 8 in Image Control's extra features.
    • Settings 1–8 are all in Customize Settings › ADJ Mode Setting on the camera; the list shows 6 lines and scrolls.
    • The lever shows every item in one row; the new items are empty after writing the firmware until they are set.
    • The extra items live in bytes the official firmware does not use, so going back to the official or an older firmware is safe.

Checked on a GR IV HDF (firmware 1.20): test firmware 072 (ADJ), 074 (HDR) and 075 (both, with the menu switch). Builds for firmware 1.11 have both as well; they were not tested on a 1.11 camera.

Notes

  • To use them, turn them on in the extra features after updating, build the firmware again and write it to the camera.
  • GR III / GR IIIx are unchanged.

Mac
