Within the last two days, I posted a picture of a Dunlin that exhibited a reticular lattice pattern in some areas of the image. I will post another image in avian which has the same pattern. Both Daniel and Artie suggested I post a sky image to see if this pattern shows up. So here for this forum, I will show the two pictures in which this pattern is quite visible and a sky shot both raw and processed with my typical workflow. I see the pattern in the sky images but it is very subtle. The last three images were taken at iso-2000, 500 mm PF with 1.4 extender, F8 for the Hummingbird picture and F-16 for the sky shots. All pictures taken with D 500, tripod for the sky images, processing with DxO photolab 2 (including prime noise engine), Topaz adjust, vignette with ON1, TK sharpening action at 10%. I have sent this information along to Nikon.
