It seems to me that a few years ago the fad was to display a small photo matted in a (relatively) very large frame. Photography magazines and books seemed to follow suit, placing small images on pages with a whole lot of white space. Based on some recent galleries / shows I've seen, it seems that this trend is coming back. I can't help but feeling a bit cheated when looking at such a small photo in a large frame; I always wonder whether the original lacked IQ or resolution sufficient for a print large enough to suit the frame, or whether the photographer is just cheap and trying to make the photo look a lot more grandiose than it actually is.
Do you think there are any compelling reasons why a given photo could benefit from being printed at small size and shown in a very large frame?
