Many of you may be aware of this, but Rebel Fish finds it pretty fascinating! There’s a custom camera being developed that captures 1 BILLION pixels in each exposure. From their Web site:

The Gigapxl™ camera captures single exposures on film with enough resolvable detail to support scanning at resolutions up to four billion pixels. Single-gigapixel images are slightly larger than 44,000 x 22,000 pixels in size and four-gigapixel images are twice as wide and twice as high at 88,000 x 44,000 pixels.

One way of visualizing the size of a four gigapixel image is to consider a photograph of a regulation football pitch (soccer in USA) which is 90m x 45m. A four gigapixel top-down photograph of the entire field at 1mm per pixel would cover an area of 89.4m x 44.7m, which is 99.38% of the indicated size. This mm-per-pixel scale represents perhaps as many as 100 pixels per blade of grass across an entire pitch captured in a single exposure.
