Sony's new 'Real-time tracking' AF system promises much improved subject tracking performance, using machine-learning, pattern recognition and much more. Here's what's changed – and how it actually performs.

We've never taken sides in the row over whether image stabilization should be provided in-body or in the lens, but we'll now list the absence of in-body stabilization as a Con in our camera reviews. Here's why.

The inability of mirrorless cameras to fire flash AF illuminators means they can't compete with DSLRs for critical shooting in low light. Manufacturers need to find a solution.

We all know what ISO means, or do we? The truth is that ISO probably doesn’t mean what you think it does, and it might be holding you back from getting the most out of your camera.

We've seen huge breakthroughs in the computational photography techniques in the latest smartphones, as well as the launch of some excellent small sensors in more traditional cameras. Does that mean that bigger is no longer necessarily better?

If it feels like we've been writing a lot about Sony recently, you haven't been imagining things: we've been writing about its products and technologies quite a bit. Here's why.

We know more about the surface of the moon and Mars combined than we do about our own ocean floor, which is why NASA Ames scientist Ved Chirayath is developing a camera that can 'remove' the water from our seas to reveal 3D images of what’s below the waves.

YouTube channel Filmmaker IQ has put together a very interesting, technically detailed, and scientifically accurate description of exactly how various image sensors (and photographic film) work. One of the best overview videos we've seen.

The Android and iOS app from Surpuba AR lets you place animated 3D models in real-world environment using augmented reality technology. You can alter poses and location, insert lighting equipment, and more... right from your phone or tablet.

Canon USA has released a promotional video showcasing its latest CMOS sensor technology. Albeit over daraticized, it’s an interesting overlook at the work it’s continually putting into its camera systems.

University of Michigan engineers Euisik Yoon and Sung-Yun Park have developed a nearly microscopic image sensor that doesn't require an external source of power.

A group of scientists at Cornell University have created an algorithm that lifts the stylistic characteristics of one picture, and drops them onto a completely different image with startling precision.

GoPro has inked a multi-year licensing deal with manufacturing services company Jabil that will allow Jabil to incorporate GoPro sensor modules and camera lenses into third-party products.

A recent breakthrough means the future could include sensors that perfectly describe the light in the scene, offer new computational possibilities and give film-like latitude in the highlights. And yet we may never see them in cameras, says father of the CMOS sensor, Professor Eric Fossum.

Panasonic has continued to develop its organic/CMOS image sensor tech, and the latest breakthrough is big: an image sensor that can shoot 8K at 60p, boasts incredible dynamic range, and has global shutter capability.

Sony has made something of a break-through in sensor development with a new backside-illuminated CMOS sensor that is capable of global shutter, a huge improvement over current CMOS global shutter technology.

Imatag is a new service that adds an invisible and indelible watermark to your images, all without any degrading effect on image quality.

AI-powered photo editing is advancing a lot faster than anybody expected. Watch as this NVIDIA AI transforms night into day, rain into sunshine, and a summer's day into a bleak winter landscape.

See DJI's 'AeroScope' drone-tracking technology in action. This is the system that DJI says can help law enforcement and airport (among others) track and identify rogue drones.

An AI-based system developed at the Max Planck Institute for Intelligent Systems is capable of creating high-definition versions of low-resolution images, using a texture-based approach.

'Project Scribbler' is a powerful AI-driven feature that can intelligently colorize a black and white portrait... or even turn a line sketch into a colorized and realistic image.

DJI has developed a technology called AeroScope that allows law enforcement to identify and track airborne drones that are breaking UAV regulations, while simultaneously addressing privacy concerns.

Crowdfunded projects have repeatedly promised to convert old 35mm film cameras to digital. "Not going to happen" says our resident pessimist, Richard. A roll of the revived Ektachrome will come sooner than a useable digital conversion.

Canon is developing a 'Free Viewpoint Video System' that will turn real life sports games and events into immersive 3D interactive experiences. It's video game-like camera control IRL.

Raw bit depth is often discussed as if it improves image quality and that more is better, but that's not really the case. And it doesn't have much to do with colors or gradation. Here's why 12-bit is enough most of the time.

Equivalence is much-discussed, but still often misunderstood. Here's a simplified explanation of the concept of equivalent apertures, which is just another way of talking about light received by your camera.

MIT has developed a new machine learning technology that can retouch an image before you even snap the photo... and it's lightweight enough that it can work on an ordinary smartphone.

Researchers with the University of California, Santa Barbara and NVIDIA have developed a new type of 'computational zoom' tech that will let you change a photo's perspective and focal length in post.

On July 12, Canon opened its newest Technology and Support Center, designed to serve the motion picture industry, in Burbank, CA. DPReview got a sneak peak and takes you behind the scenes.

Sony's new CMOS sensor is backside-illuminated and offers an all-pixel global reset function which should drastically reduce rolling shutter effect when panning.

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

Yellow shirts were big around the time of the 2014 World Cup, and red hats are on trend in December.

Microsoft has become the latest company to show its hand in the race to gain the image quality benefits of curved sensors. Its Project Vermont has developed a method for bending conventionally made silicon sensors into more uniformly-curved shapes.

Whether you're syncing a flash, wondering why banding is appearing in your image or getting strange images from your camera's silent shutter mode, the way your shutter works has a role to play. Here's what happens when you press the shutter button.

A feature we first saw demonstrated in 2015 appears to be almost ready for prime time.

The good news? a9 Raws look good at high ISO, and there's no cost to it dropping to 12 bit mode. The bad news? That's because there are only 12 bits worth of dynamic range to begin with. Rishi digs into Sony's sports specialist's sensor.

It won't end up in a smartphone or camera, but Sony's IMX382 high-speed vision sensor is still pretty cool. Read more

Reconstructing perceived images based on brain scans has proven difficult and results have been inaccurate. Neural networks may change that.
