DxO is a French company dedicated to photography. Founded in 2006, it is located in Boulogne-Billancourt.
It markets DxO PhotoLab, ViewPoint, and FilmPack image processing software and a connected camera, the DxO ONE.
DxO created DxOMark.com, which provides image quality ratings for standalone cameras, lenses, and mobile devices that include cameras. However, it has spun off from them, DxOMark Image Labs. On October 25, 2017, DxO announced the acquisition of the Nik Collection assets from Google.
DxO PhotoLab is software that corrects various optical aberrations, notably image distortion, with corrections tuned to particular lenses and cameras. It also adjusts lighting and color rendering. The software reads the Exif file to gather information about the camera, the lens, and the settings that were used.
DxO FilmPack emulates the appearance of various conventional films digitally.
DxO Analyzer is a suite of software tools, test targets, and test equipment used by camera companies as well as press publications and websites to test sensors, lenses, and standalone cameras, as well as mobile devices with cameras. Testing can be performed on both RAW and JPEG images, as well as video. DxO Analyzer is also the analysis engine behind DxOMark Image Lab's DxOMark image quality rating website. Results can be displayed either numerically or graphically. Originally introduced by DxO Labs, DxO Analyzer is now a product of DxOMark Image Labs, which has been spun out from DxO.
DxO Analyzer includes modules for testing optics, sensors, stabilization, video, timing, and 3D features.
The DxO ONE is a phone-connected camera. It is a small 20-megapixel, 1-inch-sensor, f/1.8 camera which plugs into a Lightning connector of an iPhone or iPad and uses their displays to frame and shoot an image.
Nik Collection is a collection of 7 plugins for Adobe Photoshop and applications compatible with Photoshop plugins; Adobe Lightroom and Adobe Photoshop Elements are officially supported. DxO acquired Nik Collection from Google on October 25, 2017, and it was first released as a DxO product, Nik Collection 2018, on June 6, 2018.
