PhotoShape is a useful tool to quickly reshape or deform your photos and images using your finger, mouse or pen.
The app is highly interactive and offers 10 levels of undo / redo. Press a finger (or mouse/pen) on the area you wish to deform and drag it gently to reshape the region of the image (or photo).The color boundaries are well maintained while reshaping.
With a little practice and by varying the deformation radius and pressure you can achieve very good results.
This app is useful in retouching photos for uploading to social media. It is also a useful tool for product designers.
