Absolutely - I just wanted to know how
much it would do so in a case such as this. I harboured hopes that, since the file starts as 102MP, the edited version may be tolerable at normal levels of enlargement. However, I was sobered to discovered this is not so... Obviously if one makes less aggressive corrections or shoots in a way that requires less correction, it may stray into an acceptable zone!
