No, of course not. That would be silly. And I am not silly. There are no rules. However, when the intention is to make photographs like Butcher's, which deal with the natural landscape in a traditional way, prints that have a full tonal scale will be more resonant and will be BETTER pictures. What is "better"? Those that will cause a deeper response in the knowledgeable viewer--that's better. Not to take the care to try to achieve that is, to me, inexcusable.
To go for the big print, no matter how poorly printed, for supposed "emotional impact" is a cheap (emotionally cheap) way to get a reaction. No serious collector or curator of photography gets sucked in by that stuff. That is not to say that these collectors and curators do not get sucked in by big prints. They most cetainly do, but only by well crafted ones.
