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."

Europe to Launch Massive Gigapixel Camera into Space

A 268-megapixel sensor might suffice for photographing the stars through a telescope, but apparently a sensor many times more powerful is needed for photographing alien planets from space. The European Space Agency has just finished building the largest camera ever to be used in space: a camera over three feet wide with a gigapixel sensor composed of 106 separate CCD sensors. Just to give you an idea of how powerful the camera is: it will be able to measure the width of a strand of hair from over 600 miles away, and the thumbnail of someone standing on the moon.

World’s Largest Indoor Photo Weighs in at 40 Gigapixels

Photographer Jeffrey Martin, founder of 360cities, recently use a Canon 550D and 200mm lens to shoot the largest indoor photograph ever made: a ginormous 40 gigapixel photograph of a 18th-century baroque library in the Strahov Monastery in Prague, Czech Republic. Over 5 days of shooting with his robot control camera, Martin collected 2,947 separate photos that went into the resulting panorama. The RAW photos then took a day to batch process, 111 hours to stitch, and 20 hours to Photoshop, finally ending as a single 283 gigabyte photograph.

Gigapixel Photos of Famous Paintings

We've featured quite a few gigapixel photo projects here on PetaPixel, but this one's a bit different. HAL9000 is a project out of Italy that takes famous paintings and shoots gigapixel photographs of them, allowing you to get up close and personal with the masterpieces through a special online viewer.

70-Gigapixel Panorama of Budapest Takes Over as World’s Largest Photo

Just a couple months after we reported that a 45-gigapixel photo of Dubai had become the world's largest, a new panorama has arrived to steal the crown. 70 Billion Pixels Budapest is a 70-gigapixel panorama of Budapest created using a setup of two 25-megapixel Sony A900 cameras fitted with 400mm Minolta lenses and 1.4X teleconverters. Four days of shooting resulted in 20,000 images, and an additional two days of post-processing produced a single 200 GB file. If printed, the size of the photo would be about two apartment blocks long and ten stories tall.

Two Largest Photographs in the World

It's quite a coincidence, but two of the largest images in the world were both announced recently. These images were created by taking thousands of individual high-resolution photographs and stitching them together to create gigantic panoramas.
