Quote: Macro is 1:1 or greater....no ifs butts or maybes about it in my eyes. I don't count crop factors as additional magnification and it is common to see magnification alongside format to give scale...
And yet the reality, in print, on the wall in an exhibition or as a projected image would be indistinguishable. Surely, the 'no ifs or buts' point is irrelevant in relation to what the audience will see?
