Gigapixel

A gigapixel photograph is an ultra-high-resolution image that contains at least one billion pixels, or the equivalent of 1,000 photos captured by a 1-megapixel digital camera. Gigapixel photos can be created by shooting hundreds or thousands of individual photos of a scene, generally with the help of a robotic camera mount that automatically moves the camera and triggers exposures. The photos are then typically loaded into specialized software that can automatically "stitch" the images together into a single high-resolution panorama. Gigapixel photography is usually employed in landscape and cityscape photos, though it also has uses in other niches such as macro photography to capture tiny details of small subjects. These are sometimes called "gigamacros."

How I Created a 16-Gigapixel Photo of Quito, Ecuador

A few years ago, I flew out to Ecuador to create a high-resolution image of the capital city of Quito. The final image turned out to be 16 gigapixels in size and at a printed size of over 25 meters (~82 feet), it allows people see jaw-dropping detail even when viewed from a few inches away.

This Lightning Photo is 5.45 Gigapixels

Gigapixel photos and lightning photos are generally created two different ways. One requires a mosaic of photos stitched together, and the other is usually a wide-angle view that's exposed at the moment of a lightning strike. That's what makes photographer Dan Piech's image "The Hand of Zeus" so amazing: it's a 5.449-gigapixel photo of a lightning strike in New York City.

Astronomers Unveil a 46-Gigapixel Photo of the Milky Way That Took 5 Years to Make

Last year, NASA released a 20-gigapixel photo of the Milky Way that was made up of over 2 million infrared photos. Back in January, NASA published a 1.5-gigapixel photo of the Andromeda Galaxy. If you thought those were big photos, get this: German astronomers have created the largest astronomical photo ever made: a ridiculously big 46-gigapixel photo of the Milky Way that took 5 years to make.

What 100 Million Stars Looks Like: NASA Releases a 1.5 Gigapixel Photo of the Andromeda Galaxy

NASA has released the largest and sharpest photograph ever made of the Andromeda Galaxy, the nearest spiral galaxy to ours that contains an estimated 1 trillion stars. The new image (above is a crop showing a portion of it) weighs in at 1.5 gigapixels (i.e. 1.5 billion pixels); it's so big that you would need 600HD televisions to display the entire digital photo.

Fancam Captures Massive 20 Gigapixel Group Photos of Fans at Large Events

To celebrate the return of LeBron James yesterday, the Cleveland Cavaliers decided to do a massive group photo with all the fans in attendance. Today they released the 360-degree, 20-gigapixel photograph online for fans to find themselves in, tag, and share.

The giant group panorama -- and many others like it -- was captured by a company called Fancam, which specializes in shooting some of the largest group shots in history.

This Camera Shoots a Gigapixel Photo of Your Entire Body for Skin Cancer Screening

While it’s the fifth most common type of cancer in the United States and the deadliest of all skin cancers, melanoma can often be cured if caught early enough. So, in an effort to step up early detection efforts, a team of researchers at Duke University have developed a gigapixel whole-body camera that captures high-resolution images that will allow doctors to more quickly and effectively diagnose melanoma.
