Everyone wants their pictures to be perfect and when there's a profession where the quality of photographs defines the business line, the relevance of having "perfect pictures" increases much more.Slicing, resizing or eliminating certain crooked elements of a photograph needs much more than mere editing tools. Disturbances due to light, movement, camera shakes, skin textures etc., popup further when trying to alter or usually increase the aspect ratio (size or dimension) of an image.
