Take a look at how detailed this photo becomes when you enlarge it.
If you ever wondered why drones are so successful in hitting the right target, wonder no more.
Rather hard to disappear in a crowd nowadays….The Man can see you everywhere. Pick a small part of the crowd, place your computer’s cursor in the mass of people, click a couple of times -- wait --click a few more times and see how clear each individual face becomes.
This picture was taken with a 70,000 x 30,000 pixel camera (2100 Mega Pixels.) These cameras are not sold to the general public of course.
wikipedia | A gigapixel image is a digital image bitmap composed of one billion (109) pixels (picture elements), 1000 times the information captured by a 1 megapixel digital camera. Current technology for creating such veryhigh-resolution images usually involves either making mosaics of a large number of high-resolution digital photographs or using a film negative as large as 12" × 9" (30 cm × 23 cm) up to 18" × 9" (46 cm × 23 cm), which is then scanned with a high-end large-format film scanner with at least 3000 dpi resolution. Only a few cameras are capable of creating a gigapixel image in a single sweep of a scene, such as the Pan-STARRS PS1 and the Gigapxl Camera.[1][2]
Gigapixel images may be of particular interest to the following:
- Artists
- Astronomers
- Curators and art historians, to better study artworks
- Genealogists
- Paleantologists
- Geologists
- Entomologists
- Health care providers, such as pathologists, for virtual microscopy utilizing whole slide images (digitally scanned glass microscope slides, also called virtual slides)
- Physicists viewing the results of supercomputer simulations
- Viewers of satellite composite images for various purposes, including agricultural policy, land use planning, and military intelligence
- Visual effects industry, where gigapixel images can enable the creation of immersive digital environments
- Holography
