Hi guys, I tried on my GF8 and it worked, but not perfect like I thought. Its darker than other color modes, but the color is good.
In addition, I also tried other commands. The first is vlog
http://192.168.54.1/cam.cgi?mode=setsetting&type=colormode&value=vlog_gamma
The resulted image is slightly darker than standard mode, despite the same setting. File size all larger (6.1 vs 5.6), but the menu no change like in cine D. Thus, I am not sure it works or not.
The second command is adding new af mode: 49 areas.
