Noise Profile: Panasonic DMC-GX85
100%
Description
I have created a dt_noiseprofile result for the Panasonic DMC-GX85 (also known as GX80) using ISO 200-25600 in 1 EV intervals and darktable 2.2.5. Forgot to use the 'extended' ISO 100 but if people are happy with the results here I will try to include that in a later effort.
Seems to work as expected, I like the wavelet results in particular. Does a nice job in lighter areas and is a tradeoff between noise and detail in the darkest areas.
First time working on any of this so feel free to make suggestions.

Thanks! Being this a camera I am seriously considering to buy... I hope the developers now that the 2.2.5 has been published will have time to collect and give feedback on the new cameras :-)

It is best to include all possible iso's since the beginning, because replacing noiseprofile technically changes output.
Also, it is really best to take a sample at each iso level that can be set in camera.
Because alternatively, the data will be linearly interpolated

Now that I know the process, it wasn't too hard to re-do it.
Attached is a profile from all available ISO settings on the camera 100-25600.

ISO 100 profile looks wrong. Pherata "extended ISO" ist not a real iso value but calculated afterwards.
Can you please upload you ISO 100 sample and I try to get a better matching or I have to remove the ISO 100 entry.

Here is a ISO100 sample taken with my GX80, assuming there is no true "ISO100" value in the camera settings, you have to enable the extended ISO setting to add ISO100 value. The native ISO range on GX80/85 is from ISO200 to ISO 25600

Could you please copy-paste these results also for GX80, which is just a European name for GX85? I've tried it by manually editing noiseprofiles.json and it works with my GX80.
