Now entirely focused on software development, DxO has nevertheless stayed the course with a perpetual licensing model for PhotoLab, eschewing the controversial subscription-based pricing that rivals like Adobe have used to increase revenues. It has also shuttered its nascent hardware business altogether, and spun off its DxOMark camera, lens and smartphone testing lab as a separate company in 2017.
