GR Mod 0.8.10

改动(GR IV / GR IV HDF)

  • 白色光晕三档重新调过,更像 HDF 和黑柔滤镜。
    • 弱 / 中: 改成柔光滤镜的做法(大约相当于黑柔 1/8、1/4)。画面里所有的光都有一小部分(8% / 15%)向四周散开:灯周围是柔和的光晕,人脸、中间调有一层很轻的雾,最亮的地方不再糊成一片白。
    • 强: 还是原来那种光晕,但从更低的亮度(约 60%)开始,强度减弱,中高光也会发光。
    • 红色光晕完全没变。相机里的设置方式也没变(Fn 子菜单选颜色和强度),以前存的设置照样对应同一档。
    • 白色的弱 / 中要处理整张画面,每张照片的处理时间比以前的白色光晕稍长。
  • HDR 增益图的提亮更克制。 从更亮的地方开始提亮(线性亮度 0.6,原来 0.35),最多提亮 1.2 档(原来 2 档),参考 ITU-R BT.2446 的做法,并用 DNG 实测核对过:白墙、白衣服、人脸亮部不再“发光”,灯、窗外、强反光仍然会亮起来。

已在 GR IV HDF(固件 1.20)上实测:测试固件 076(HDR 新参数)、077(白色光晕新三档)。固件 1.11 上同样生效,但没有在 1.11 的相机上实测。

注意

  • 想用新的效果,更新软件后请重新生成固件并写入相机。
  • GR III / GR IIIx 不受影响。

Changes (GR IV / GR IV HDF)

  • White halation's three levels, closer to the HDF and a Black Pro-Mist filter.
    • Weak / Medium: now a diffusion filter (about a Black Pro-Mist 1/8 and 1/4). A small share of all the light (8 % / 15 %) is spread around: lamps get a soft glow, faces and midtones a faint haze, and the brightest parts no longer turn into a white patch.
    • Strong: the earlier glow, starting lower (about 60 %) and weaker, so bright midtones glow too.
    • Red halation is unchanged. The camera settings work as before (colour and strength in the Fn submenu); saved settings keep their level.
    • White Weak / Medium process the whole picture, so each shot takes a little longer than with the old white halation.
  • The HDR gain map lifts less. It starts brighter (linear light 0.6, was 0.35) and lifts at most 1.2 stops (was 2), following ITU-R BT.2446 and checked against DNGs: white walls, white clothes and bright skin no longer glow; lamps, windows and strong reflections still light up.

Checked on a GR IV HDF (firmware 1.20): test firmware 076 (HDR) and 077 (white halation). Builds for firmware 1.11 have the same changes; they were not tested on a 1.11 camera.

Notes

  • To get the new looks, build the firmware again after updating and write it to the camera.
  • GR III / GR IIIx are unchanged.
