Digital Camera World Verdict

DxO PureRAW 4 does have a couple of limitations and drawbacks, but the transformation in raw image quality it produces is hard to resist. Its high-ISO noise reduction and detail restoration is breathtaking, its enhanced edge softness correction can make ordinary lenses look great, and it even works neatly alongside Lightroom. The drawbacks? It produces DNG files 2-4 times larger than your original raws (or even more) and its ‘Standard’ lens sharpness setting can be a bit fierce.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

If you use Lightroom, Capture One or some other software to view and process your raw files, you’ll have formed a good idea of the quality you can get from your images. If you try DxO PureRAW 4, you might just have to change your mind.

Almost all image editing tools can now process raw files. They do this using the software’s own proprietary ‘demosaicing’ process to turn the red, green and blue sensor data into full colour images. Some do this raw processing better than others, however, and if you use Adobe Lightroom, for example, you might end up with a completely different idea of your camera’s image quality than if you use Capture One. Even the best photo editing software can have weaknesses, and sometimes it's the raw processing quality and noise handling.
