Pinch

Pinch is a plugin for Adobe Photoshop that applies a compressional distortion. Pinch comes with lots of options for optimal tweaking. Both horizontal and vertical pinching can be applied uniformly or independently, out-of-bounds coloring can be modified, automatic image scaling compensation can be enabled, independent color channels toggled and of course, powerful interpolation options including nearest neighbor, bisquare, bicosine, bilinear and bicubic for ultra-smooth antialiased results. Pinch supports both 8 bits / channel and 16 bits / channel color modes for professional workflows.
