The second shows a fine vertical element BARELY seen. It is seen meaning the pixel calculatons are NOT taking something into account. On the left side many rebar are clustered making a better exposure. Low, on the right the resolution is not adequate to capture the lower part of the rebar meaning the pixel calculations are partially right, proving the small size.
What the hell are you trying to say here? Could you, please, atleast make an effort on making coherent sentences? Jeez, your writing is almost as foggy as your brain.
And where is my requested picture where you point out the rebar?
