It has a single license for four applications:* A version integrated in DxO PhotoLab (and DxO OpticsPro)* An independent version (standalone)* An external module (plug-in) for Photoshop, Photoshop Elements and Lightroom* Modul for Nik Collection; Perspective efex * In the integrated version in PhotoLab, the tools are available via two Read more…
Before correcting the image geometry, it is necessary to pre-correct lens distortion. Integrated PhotoLab Version This step is transparent since performed automatically for the supported lenses. Independent version plug-in for PS / PSE / LR ViewPoint accesses the lense database characterized by DxO and has the same automatic distortion correction Read more…
This correction seems simple but must be very precise in case we need to work on the perspective. Cases where it is not necessary to correct the horizon * When the photographer has intentionally applied an important angle while shooting There must be no ambiguity about the original Read more…
The Automatic horizon correction is a particularly effective tool when ViewPoint finds sufficiently horizontal or vertical elements in the picture, even of small size. The presence of verticals is particularly successful in the correction.In palette “Horizon” – ViewPoint: “Auto” button– PhotoLab: Magic wand The grid display allows visualizing horizon defects Read more…
Manual horizon correction is used when the result of the auto step is unsatisfactory and as a preliminary to a manual correction perspective. The difficulty is to find the right element truly horizontal on which to relyIn our contemporary environment, vertical lines are most common.Finding a vertical passing through the Read more…
Totally corrected, or not, remains the choice of the author of the picture. Totally correcting the perspective is sometimes necessary: descriptive or architectural photo, panoramic preparation, etc … For the other cases,the intended use of the image needs to be considered, the output format, and of course personal taste! Plan for perspective Read more…
Success of the automatic perspective correction depends on several criteria:* The presence of enough vertical and / or horizontal components* Absence of disturbing elements (remarkable neither horizontal nor vertical lines) When these conditions are met, ViewPoint gives very good results. In palette “Perspective” – ViewPoint: “Auto” button – PhotoLab: Magic wand A successful Read more…
Perspective correction by the verticals In palette “Perspective” – ViewPoint: Button “Force vertical parallels”– PhotoLab: Button “Force parallel”ViewPoint only: The Tab[ulation] key is used to navigate from one marker to another. Perspective Correction by Horizontals Contrary to the correction by verticals which is in common use, correction by horizontals is limited Read more…
The scope of manual perspective correction is for expert users who wish to have control over the entire correcting process. A successful manual correction gives the best possible result, which can be very close to what allows a tilt and shift lens. These manual settings can also be used to fine-tune Read more…
Volume deformation is manifested by a change in the appearance of the components of the photo that are increasingly stretched towards the edges of the image. It is characteristic of a wide-angle lens usage and increases with the decrease of the focal length used. We usually start noticing below 28mm Read more…
