We take one image and process it using 4 or 5
different tutorials to compare results. For example,
there are many tutorials on making a sketch from a
photo, but there are only a handfull of methods used.
Some methods used are the Color Dodge-Invert
method, the Motion Blur-Invert Method, the Divide-
BlendMode, Method, the Custom Filter Method. We
have chosen representative tutorials for each method.
