[QUOTE="spb_stan, post: 683595, member: 43545"] These images are shaped but inspecting the small jpg first image showed the hard contrasty light generated a lot of pin-points specular light on each of the points of the scales. That can decrease the perception of detail. Detail is aplenty in each of those shot. The ISO on one of the last ones was up to 1000, which also robs detail. I downloaded the first one to look at more closely and backed off the contrast and saw an improvement in detail but the specular highlights are blown out so that data is gone. In such hard contrasty scenes, using the cool feature of the D850 "Highlight-weighted metering" could assure specular highlights are not blown. These animals are slow enough moving to use lower shutter speed to be able to get deep enough of field and not lose detail in the dark areas. These sensors have about linear "iso'less" dynamic range degradation with sensitivity. That means every stop increase in ISO results in about 1 stop less dynamic range. One of the great features of the D850 is a low native ISO. If that image was shot at OSO 64 or 50 ISO the contrast would be better dealt with. That is 3 full stops less DR at 1000 ISO than ISO 64.
