You know, there are all kinds of ways you could have expressed that without going for a wholier-than-thou kind of position. What defines a quality print isn't just so much the DPI as it is the content of the image and how that renders at different sizes. I agree that for some images, you're entirely right (an example, I tried upscaling a picture I had for an exhibit and it looked horrible, so I stayed with the smaller size), while there are others where upscaling doesn't take away from the picture (there's another picture I have that I upscaled with photoshop to be printed on a huge printer, just for kicks, and it came out surprisingly good!). Furthermore, have you taken a close look at some pictures that are exhibited out there? I went looking at pretty big prints of David Lachapelle some time last year, and amused myself with basically pixel peeping those prints. And sure, when you're close to the picture, even the plane of focus is blurry... but you don't really look at a picture at such a close distance, do you? You take a couple of steps back to take in the whole picture, don't you? What does the picture look like to you then? So please, I can perfectly understand not upscaling now or ever from a purely programmatic point of view. Maybe you'd rather leave that to some other software for all I know, because it already does this perfectly well? But as for judging the quality of a picture, PLEASE leave that to each photographer and his/her intent. It's really not your job or priviledge to pass judgement on pictures or prints thereof when you haven't even seen them.
