DxO is unsurpassed in its field of application and stands in almost immeasurable field of EBV software clearly visible. By applying the correction data of the specific camera / lens combination image improvements are possible, that I could not achieve with other programs (eg Lightroom). Above all, the dreaded color aberration at wide-angle shots can be virtually 100% correct. The typical example: branches of a tree in the backlight on the screen at 14mm focal length. Here occur even when using high-quality lenses and small aperture (eg Nikkor 14-24mm f = 8) in full-frame in the edge region still relatively pronounced green and purple fringing or. DxO eliminates this completely without loss of image quality. The PRIME-denoising and the many possibilities of selective brightness correction of highlights are quite outstanding. The operation guidance is (with a few exceptions) very intuitive and simple, the program works with full 16 bit / color channel and makes color management. But does not replace other DxO image processing software (eg Lightroom o. Ä.) Completely, it complements perfectly. I use DxO as extremely luxurious and powerful RAW converter a, producing DNG or TIF images and then processed them with other programs. One should also use a relatively powerful computer (i7) with enough RAM and possible SSD drive. DxO allows pronounced multicore use, so powerful hardware also contributes to noticeable acceleration. Due to the great performance of DxO therefore I express my full recommendation. Whether the pricing policy with a reasonable "standard" (DX) - to approve and an expensive "Elite" version (FX), naturally separates the spirits. Total DxO (Elite) is not cheap, but offers a great deal and not available especially in this form in other programs performance for the money. And Adobe & Co. also are not exactly squeamish in terms of their pricing policy.
