Re: ISO25600 from GX7, Photo style NR=-5, 0 and +5
2

As promised, had carried out a test using ISO25600, Standard Photo Style having NR set to -5, 0 and +5, took 12 images for each of the setting under M-Burst, and used Median stacking plus some minor sharpening in Photoshop.

The original OOC jpg scene (NR=-5):

Cropped and compare the original of the 3 NR settings as below:

After stacking the cropped result as below:

Conclusion:

Looking at the originals, NR-5 and NR=0 produced similar amount of detail and NR-5 of course is the noisiest. NR+5 had fine detail be erased despite it is the cleanest. So, it seems that NR0 be the ideal setting for OOC jpg.

The stacking results are quite close to each other and it seems that NR0 produced the best result (enough detail, similar noise condition to -5), closely followed by NR-5, and NR+5 be the worst of the pack (relatively noiser).

So, I think I shall change my C perset to NR=0 as NR-5 did not give me any obvious advantage.

The following are the stacking results:

NR-5, Median stacking by 12 OOC jpgs

NR0, Median Stacking by 12 OOC jpgs

NR+5, Median stacking by 12 OOC jpgs
