New Google research thwarts automatic watermark removal

A team of Google researchers have found that slightly warping watermarks when embedding them into images can help prevent automatic removal.

Scientists 'upload' a horse GIF onto bacteria

Could the future of photo and video storage be... alive? Scientists at Harvard have managed to encode a GIF of a galloping horse into a live sample of E. coli.

Caltech research team develops lensless camera

Caltech researchers have developed an 'optical phased array' chip that uses time delays instead of a lens to focus the incoming light.

MIT previews autonomous tracking drone

The MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a drone that does not require any human control for recording tracking shots.

This CMOS sensor with 3D-printed microlenses is designed to mimic predator vision

Using 3D printing to create ultra-precise micro-lenses directly on a CMOS sensor might one day help drones see the way eagles and other predators do. Read more

Tiny fps1000 high-speed camera boasts 18,500fps

Graham Rowan of Hertfordshire, UK has created a small camera dubbed the "fps1000", and as its name suggests, it is designed solely to record high-frame-rate videos. The goal is to open up high-speed shooting to a wider market by offering a relatively inexpensive product that is highly portable. Learn more

'Cities at Night' project puts citizens to work identifying images of Earth

Got a few minutes to spare? You've got enough time on your hands to help a group of researchers tackle a massive problem. Cities at Night is a project aiming to recruit help from ordinary citizens in classifying images of Earth at night taken by astronauts aboard the International Space Station. An effort of Universidad Complutense de Madrid staff and students, their main goal is to better understand and reduce light pollution. See how you can help

Algolux aims to simplify lens design through computational imaging

Virtual Lens technology could help make optics smaller, lighter and cheaper.

ETTR Exposed
21

ETTR, Exposure to the Right, results in an exposure that maximizes captured signal-to-noise and provides the best information from which to base a final image. This can be achieved in several ways. ETTR images of scenes with low-DR and high-DR require very different processing steps.

Color Management – a Walkthrough

Color Management can be confusing. Here I hope to explain how the colors you photograph can be made to survive reasonably intact as they move through the five major color spaces usually encountered from shot to print or post: camera, camera jpeg processor, image processor, monitor, and print or web.

Exposure vs. Brightening
33

Exposure is determined by the luminance from the scene, the f-ratio, and the shutter speed — only. All other procedures, either in-camera or with the computer, to affect the brightness of an image, including ISO, comprise brightening -- a concept essentially different from exposure.
