Blue noise in dark areas of TIFF export

[georgepeter]

I am exporting to TIIFs from 4K original. The picture was color corrected by the DP. I am getting blue noise in the shadow area as well as some red. Has this been seen before and is there any known resolution?

Any help would be greatly appreciated.

Thanks,

Tony

Definitely more blue noise was noted in the earlier firmware builds. I presume this was shot on the current release build 16, though? Blue channel noise was visibly improved in build 16 but if the lighting color temperature was low (tungsten) and the overall light level was also low, there will always be some noise that color correction may bring up. However if you have red noise as well, it can't be blamed on the lighting color temp. alone.

If these are Tungsten balanced shots try exporting them at Daylight balance and then fixing the colour temperature in whatever online program you're using. See this thread for more info:
