Software to correct lens distortion is a great tool for enhancing your shots and getting rid of the unnecessary aberrations that are usually caused by the lens focal length, camera model and even the lens itself. These programs feature automatic and manual instruments for editing various types of pictures.
Meeting the needs of both professional and beginning photographers, such software will be especially useful for real-estate and architectural shooters.
Almost all lens distortion correction software listed in this guide have a preview function that allows you to evaluate the result and decide if it is satisfactory. Some tools are designed for fixing lens distribution, and the task of others is to improve images by adjusting lens distortion.
Verdict: PTLens is a highly functional tool that has various features for correcting lens distortion, vignetting, color fringing and perspective. By using this software to correct lens distortion, you can easily reduce the barrel aberration produced by wide-angle optical accessories.
In most cases, this type of distortion appears, when horizontal linear elements are represented as curved in the picture, and vertical elements, such as buildings, taper towards the top to cover the frontage in the photo. PTLens enhances such images by correcting the color dispersion, perspective distortion, rotation, etc.
PTLens also offers special instruments for turning fisheye images into straight-line pictures. This does not require calibration as maximum flexibility is ensured by the sliders.
Verdict: Photoshop is regarded by many photographers as the best tool for editing images and one of the greatest lens distortion correction software. Use this photo correction tool with layers support for editing and enhancing your shots.
