234Sources of noise part two: Electronic NoiseMay 13, 2015 at 19:09

Following on our look at the effects of shot noise, our attentions turn to the electronic noise added by your camera. In this second part of the series, we look at read noise and how your sensor's behavior defines what your camera is capable of and consequently, how you should shoot with it. Read more

100The effect of pixel size on noiseMay 3, 2015 at 07:26

A quick look at the effect of sensor size and pixel size on noise.

713What's that noise? Part one: Shedding some light on the sources of noiseApr 27, 2015 at 16:00

How would you react if you were told that the aperture and shutter speed you choose make more difference to image noise than the ISO setting? You might be surprised to discover that a lot of the noise in your images doesn't come from your camera at all: it comes from the light you're capturing. Our own Richard Butler explains. Read more

2349What is equivalence and why should I care?Jul 7, 2014 at 10:00

Equivalence, at its most simple, is a way of comparing different formats (sensor sizes) on a common basis. Sounds straightforward enough, but the concept is still somewhat controversial and not always clearly understood. We thought it was about time we explained - and demonstrated - what equivalence means and what it doesn't. Learn more

0Sense and SensitivitySep 29, 2009 at 19:19

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.
