In fact there is a peripheral band degraded gray more or less important (a few pixels wide) which gives an impression of blur (It can be observed at very high magnification by zooming to 400% and more). This characteristic of a camera lens is called the sharpness.Ĭonsider a black shape on a white background, the border pixels should be either black or white. The Unsharp mask (or increased sharpness) is a trick to sharpen the image. (*) DxO has since been split into two companies DxO Mark which characterizes the hardware and DxO Labs which develops and publishes software The sharpness of the optics – Chromatic aberration in the Detail paletteĪ highlight of PhotoLab is that it activates these corrections by default with the starting preset. – Sharpness of the lens in the Detail palette It is interesting to get an overview of the work already done by temporarily unchecking the four corrections via the blue square to the left of the correction title. However, PhotoLab is able to open a JPEG picture from any digital camera too. Camera body or lens are not selectable independently. The requirement is that the camera has been characterized in the DxO lab. It is an important element for the choice of PhotoLab because very often the beginner photographer has a modest material on which the improvements of the software do wonder. The correction of optical defects is the core business of the company DxO (*) well before it proposes its development software. Let’s go back to the technical prerequisites of PhotoLab that we have not presented. The development of the image is finished.
