I don't think I've put this up here before: The Gigapxl folks are shooting 9"x18" film and scanning it. The image gallery is worth a look through, keep clicking 'til you get to one of 'em where they show the extreme detail stuff.

Bah! Try strapping a camera like that to the bottom of a high-altitude jet and snap pictures every 30 secs. Then scan the imagery georeference and georectify it (that is, warp the entire image according to the pitch and roll of the plane plus the actual terrain elevation). Then every pixel corresponds to points on the surface of the Earth. Do this from a sattelite and you have Ikonos Quickbird.

Now for the fun part: you have all these monstrous images and you want to be able to access the information in some logical way - maybe compare the information with field data on natural disasters. So you are doing differences across several of these images to detect change... What if you extend the imagery beyond visible? How 'bout four more bands beyond RGB into infrared (like Landsat 7)? And this thing passes over every point on the surface of the Earth every 16 days?!?

The Gigapxl is neat at giving you an idea of the differences between consumer digital and large format film (and even 35mm film, for that matter). But it's nothing new...
