The Largest Digital Photo

Gigapixel writes to point us to what is claimed to be the largest digital photo on the Net, at 8.6 Gigapixel. It is a composite photo of the "Parete Gaudenziana," a fresco painted by Gaudenzio Ferrari, dated 1513. This fresco is in the Church of Santa Maria delle Grazie, in the convent of Varallo Sesia, diocese of Novara and Province of Vercelli, Italy. The site uses Flash to let you explore the fresco over a zoom range of more than 180 to 1. The photo is made up of 1145 images, each 12.2 Mpixel and 16 bits per color channel. Read on for more technical specs of the photo.

Huh?

If a composite photo is eligible to be called "the largest digital photo on the net", then sorry, wrong...

What about Google Earth. That's a huge scrollable and zoomable digital photo, bigger than Gigapixel's efforts.

Stitching together 40x40 digital photos = cool.

World's largest digital photo it is definitely not.

OK, so I can concede that physical gigapixel cameras may be unrealistic, but couldn't effective gigapixel cameras exist? For example, if a single pixel camera as referenced this past week on /. could take high resolution shots, couldn't they stretch out the technology to work for ridiculously hi-resolution photos?

I'm not an optics expert, just a tech optimist. 10 years ago I interviewed at IBM when they were working with Cyrix to match Intel chips. The engineering Director that interviewed me went on and on about how it would be impossible to create chips below 100nm (or .1 micron as he said) due to some type of Quantum interactions. Yet today Intel is testing 45 nm chips, and Cyrix is forgotten.

Someone will always find a work-around to push a technology's limits well beyond the end point demarcated by yesterday's experts.
