question where in the hell is white noise taken on Z6 with FTZ nikon gen 1 70-200mm 1/1000 sec. f/2.8 82mm at ISO 10000 not sure if had - to exposure computation or not at one time lowered down to -1.0 since had to shoot at 10k iso. also been over 1 year and 3 months since have not shot volleyball oct 10 2019 and last week was first time in 11 months since shot sports since last year was around end of feb early march from virus. this is jpg. raw does not show any white noise too. also did not use topaz Denoise too. since going threw files now. so have not done any editing yet at all only just quick post from jpg file i got off camera. will do edit later after done going over all files to pick from and edit. not sure why photo on top
