How about resolution?

Scenario B

Does anyone really think that some people don't know that A has more resolution than B? Yeah, it shows so many line pairs/so much area.. yaada yaada and one can talk about how Fourier transform or that nyquist frequency can explain them. But everybody knows what they see, Resolution = Detail. A and B above you can count and discern the same number of lines. The resolution of A and B is the same.

Now, we must talk about real world, because that is the norm in this forum (as if we can ever capture something that doesn't belong to this world:P).

Scenario C

A has more resolution than B, because we can count 1753 hair in A vs 1248 hair in B.

Now, let us look at scenario B and scenario C again. In both cases A looks sharper than B. What does that mean? More resolution = more sharpness. That is resolution = sharpness in this two scenarios. And almost all scenarios are like this. So, we can actually use the terms resolution and sharpness interchangeably.

Not the case at all. In scenario B...the resolution of the two images is equal. Sharpness though differs.
