Description

The profiles for Adobe Camera Raw and Lightroom provided by this collection correct the optical aberrations commonly found in “classic” Pentax lenses, vignetting, and distortion. They are activated within the Lens module in Camera Raw and Lightroom. For the vast majority of lenses, a set of several individual profiles is provided (e.g. for open aperture, f/5, 6, and f/11), and for zoom lenses, different correction profiles are provided for the most common focal lengths (e.g. 80, 100, 135 and 200 mm for a 80-200 mm zoom lens). All profiles were created with Sony “full-frame” cameras (Sony A7, A7R, A7R II and A7II), but can also be used for cameras of other sensor sizes and manufacturers. All have been checked against photos of various subjects and reissued if necessary. The correction profiles included here are particularly useful for landscape and architecture shots with wide-angle lenses or zoom lenses, as they then largely eliminate the sometimes very annoying edge shading and curvature of straight lines. However, they ensure natural-looking photos free of geometric distortions in any kind of imagery (portrait, fashion, reportage, cityscapes, etc.).
