DxO ViewPoint 2

ViewPoint 2 from DXO is a photo editing software package that allows you to correct distortion, perspective, and deformed proportions along the edges of your photos easily. It works especially well with photos taken with wide-angle lenses, which usually have distorted edges. When using ViewPoint 2, anchor points are placed on parts of an image that should be straightened or be on the same level. ViewPoint 2 provides a loupe tool so you can precisely place your anchor points, and slider controls allow you to precisely adjust the corrections.
