Next: Upgrading from LR 4 easily. Catalogs and presets are transferred without any further effort. The most important innovations: The new exemption overlay clearly shows spots caused by dust on the sensor. The Bereichsrepararaturwerkzeug can finally touch up irregular and elongated objects. Toll: the radial filters. For Vignetttenzeichnungen he is probably less used. Enormously effective it can be used especially for exposure corrections in image portions. But most is the new perspective correction. Really great. But these last two features make the upgrade absolutely recommendable. You have to know what they can and how to use them only.
