This must be it. I spent some time examining prints under a loupe trying to figure out why I always like the LF 8x10's better, but there were very few quantifiable differences at that size. MF is grainless, and 35mm is pretty close to grainless at this size, but there is something in the tones of the 4x5's that just gives them a wow factor. I'd always just kept the LF gear in reserve for times when I needed a large print, but I think I'll be using it for more subjects now.
