Before-and-after image of the photo editing leading to the current image
This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: took both outer PCs left and right and individually removed the persperctive distortion with IrfanView Plugins, then turned them both so that all three are in a line, then filled up empty spaces resulting from the former operations in GIMP. The original can be viewed here: Trinity77.jpg: . Modifications made by Pittigrilli.
