Correzione lenticolare utilizzando digiKam

Trascritto dal blog di Mohammed Malik, 18 marzo 2011

Nessuna lente è otticamente perfetta. Anche le più costose hanno delle imperfezioni, tuttavia digiKam può correggere le imperfezioni delle lenti come la distorsione, l'aberrazione cromatica, la vignettatura, il colore e la geometria.

Choose the picture that you want to add corrections to and press F4 on the keyboard. This will take you to Editor view. In the Editor view go to Enhance -> Lens -> Auto Corrections.

This feature uses lens data from the lensfun library and it has a very much up to date database of lenses which are available. It has more than a hundred lenses in its current databases. It also uses the metadata from the image to find-out which lens is used. If the exact used to take the picture is available it will mention that it matches with the meta-data, however if the exact match is not available it will choose the settings from the most closes match. In this case it also allows users to select the lens themselves.

You can either enable or disable the grid lines. Select the corrections you want to apply move you mouse inwards and outwards of the preview window which will show you before and after. When you are satisfied with the result press OK.
