For me, 'Rail House in Yellow" is truly evocative. Tariq (I think it was) showed us recently that SPP crushes the blacks before we even see any images in the processor window, and he and both feel that this is part of the "Foveon" look (that and incredible detail). That image will print like film—and the attractiveness of it is not just the nostalgia of the film look (I don't think); it's as much about reducing the reality of the experience to its elements—as much about what is suggested as what's explicit.
For example, with DR 400 set, the X-E1 probably would have given us details on the posts' surfaces that are facing us, but the image above suggests their presence instead. The overall effect of this (perhaps part of the alleged 'Foveon' look) is that the graphic elements emerge. For me personally, this is how I remember things, and I think that's where the nostalgic aspects arise. Just 2¢'s worth.
