Process - Photograph something with squarish proportions (window). Down load the image into your photo editing software, (Photoshop). Add 50% white space to all four sides (Image, Canvas Size). Using spherize filter compensate for the barrel distortion of your camera lens (-10). Using skew transformation (edit, transform, skew) bring edges of window back to orthogonal alignment. Using the scale transformation (edit, transform, scale) make width and length of the window equal bring it back to its original square proportions. Crop down but leave the skewed edges.
The now mutated photograph evidences a corrected camera based point of view written into the elegant slopes and overall geometry of the image.
