Sony a9 III: Global shutter comes with an image quality cost

Sony says the a9 III's sensor offers "global shutter without compromise." Our studio tests suggest this isn't quite the case. We've taken a closer look at the image quality and dynamic range impact of the move to a Stacked CMOS global shutter sensor.

Why do you need DR: a closer look at dynamic range Part 3

Having suggested that DR numbers say less than you might expect, what's the value of a camera offering more than the roughly 9EV of DR that a typical JPEG shows?

How numbers can mislead: a closer look at dynamic range, Part 2

Having said that dynamic range numbers don't tell the whole story, we take a closer look at the bigger picture and the role played by noise.

More than a number: a closer look at dynamic range, Part 1

Dynamic range numbers get widely discussed but don't necessarily tell you as much as they might seem. We take a quick look at why DR numbers are only a small part of the story.

Panasonic GH6 looks good for most shooting, but low ISO DR falls behind

We've shot and examined our studio scene, and its images are a match for the OM System OM-1 in a lot of circumstances. Digging into the shadows shows there's a dynamic range cost at low ISO for this clever, fast sensor.

OM System OM-1 studio tests published

Some ambitious claims have been made about the OM System OM-1's image quality. We've shot our studio scene and dynamic range tests to see how it performs.

What is dual gain and how does it work?

The Panasonic GH6's 'DR Boost' mode is based on an interesting sensor design, but it's not the same as the 'dual gain' chips we've become accustomed to. We look at the differences and why you use gain at all.

Panasonic Lumix DC-GH5 II added to studio test scene

We've shot and processed our standard studio test scene for Panasonic's Lumix DC-GH5 II (GH5M2). Our review will focus mainly on video, but talk of improved dynamic range made us want to check whether we could see an improvement over its predecessor.

The EOS-1D X Mark III shoots Canon's best-ever JPEGs

There's a lot that's new in Canon's flagship EOS-1D X Mark III, including a sensor that offers best-in-class dynamic range. It also happens to produce the best JPEGs we've seen from a Canon camera – take a look at our test scene to see for yourself.

Nikon Z6 image quality and dynamic range impress, but not without caveats

The Nikon Z6, paired with the new Nikkor Z 50mm F1.8S produces the sort of result you'd expect from a baby Z7. The lens is consistent across the frame and the sensor looks good but, like the Z7, the PDAF stripes aren't perfectly corrected so can occasionally become visible.

Sony a7 III dynamic range and high ISO improve over its predecessor

On paper, the Sony a7 III is a tempting option for photographers who've been considering a switch to full-frame mirrorless. But how does its image quality stack up? We compare it to the Mark II and a few of its other peers.

DPRSplit will help pull more dynamic range from Canon 5D Mark IV Dual Pixel Raw files

DPRSplit can help you pull about +1EV of usable dynamic range from Canon's 5D Mark IV Dual Pixel Raw files—as long as you don't mind a bit of parallax error, that is.

This eclipse photo shows the crazy dynamic range of today's image sensors

Yet another reason to always shoot Raw. These two shots are actually the same photo, photographer Dan Plucinski simply pulled up the shadows in post.

Sony a9: more speed, less dynamic range

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.

Canon 5D Mark IV brings dramatic dynamic range improvements to the 5D line

The 5D Mark IV promises significant improvements in dynamic range, something many current 5D-series owners have longed for, according to Canon's own market research. How does it fare? We take an in-depth look. Read more

The art of HDR photography part 1
The first chapter of this series covers the basics of High Dynamic Range photography. Future chapters will cover capture, workflow and advanced HDR techniques.
Sense and Sensitivity

Sensitivity (ISO) in digital imaging is the subject of quite a lot of confusion - it's becoming common to hear talk of manufacturers 'cheating with ISO.' Here we look at why sensitivity can be hard to pin down, why we use the definition we do and how it's really as complicated as it can seem.

Behind the scenes: extended highlights!

Feature: Apical dynamic range interview

Dynamic range and the various ways of trying to capture and represent it are the topic of many a heated discussion on the forums. We spoke to Apical, a company working on this challenge whose technologies are incorporated in cameras from the biggest brands, to find out what it is doing to address the matter. We think this interview with managing director Michael Tusch will help shine a little light on this shadowy corner of image processing.
