value of FF sensors ? (for most of us ?)
8 months ago

Opening up a can of some tired worms, and with not much else to do on these cold winter days, here we go again: What I miss on many of these previous post on this topic is following:

When facing the impact of a well done image, ultimate sharpness, line resolution, alone are not the only deciding factors in its quality of quality rendering of the original object. There exist numerous articles and tests which show that high resolution sharp images will appear dull and "lacking of focus" if contrast, clarity, dynamic rendering is missing.

Prime sample of that concept is the human eye: while its power of resolution is relatively small, due to its single lens, the image it projects appears to be stunningly sharp, as is surprisingly clear, of high contrast and dynamic rendering of colors. Which is why hardly any photograph will surpass its performance in IQ (and I have a hunch that there might be also a substantial amount of "PP" being applied by the brain).

That may explain why well post processed images can be stunning, since clever PP can recover much of the image quality lost when light passes through many layers of glass.

It also explains why cameras with good lenses, but of low pixel count sensors of some P&S cams can produce stunning IQ pictures. The market of common users, like most of us, has fallen victim to the Mega Pixel Hype ?

Naturally, FF and huge amount of Pixels is needed if images are blown up to poster size. But how many of us do that ? Most PC / TV screens are max out at 2 MP. And: who sticks his nose close to the print if it is wall size ?

Looking at power of resolution is half the story. A good lens makes a compromise between resolving power, contrast and dynamic reproduction of colors. Post Processing can recover what a cheaper lens fails to do. The message here is, instead of spending much money on good glass, perhaps investing time and money in PP is the cheaper and better way to good IQ in our pictures.

Image done with a 12 MP sensor, of the size of 1/4 of an ASP-C (Nikon P7800), with just a some contrast and a bit saturation added. Stunning, eh ?

Not afraid of your opinions
