Nikon D810: What You Need to Know

Right, demosaicing and sharpening (and also upscaling) algorithms are essentially guessing and manufacturing more details, more information from limited amount of information. Often they get good enough result, so it looks okay, but bear in mind that the minute details are not really captured by our Bayer masked sensors.

I guess it works well for charts and scientific resolution comparison but what about real world use? Sharp lenses have the risk of getting moire and other artifacts while you try to get the most of your image and similarly less sharp lenses, or smaller apertures where diffraction starts to show, act well as a lowpass optical filter, to get more uniform light distribution over those colored subpixels.

In the end it will depend on the situation, like usually 🙂
