This might be almost a philosophical question, but anyway...
A bright sunny day here today so I spent some time at a classic car show, got a few pics of these legendary Australian beasts.
D7200, ISO100, 1/200sec at f7.1 with the the Nikon 16-80 f2.8-4.
I shoot RAW and JPG ('standard' picture control). Having a look at the JPG files in Capture NX-D I noticed that the camera did apply a small amount of NR to the JPG. When viewing the RAW file, Capture NX-D allows me to 'toggle' between zero NR and the NR the camera applied to the JPG - a small amount (Intensity 2, Sharpness 5 using the 'Faster' method). Viewing the full image, that bit of NR seemed to come at a slight loss of sharpness. This got me curious as to where the noise was in the image - so I zoomed to 90%.
The black areas in the engine bay looked fine. There was some speckle on the chrome air filter at the top of the engine, on the wheel rim and in the red area of the from fender that's not in direct sunlight. All detectable at 90% (particularly when toggling between NR 'on' and 'off'), but not (on my monitor at least) when viewed at full-frame. The slight loss of sharpness, however, was detectable when the image was viewed at full-frame.
This is where it gets philosophical: it was when I was zoomed in that that wheel rim at 90% that I thought to myself, should I really stressing about this? I'm zooming it to a wheel rim! Noise should low at ISO100, and any noise in this image is unlikely to detract from it at all. I also like to have as little sharpening and NR processing as possible applies to my RAWs.
Am I getting over-analytical here? Am I spending too much time zoomed to 90%? keen to hear what people think.
