I've been studying the golden ratio (or golden number or golden mean) and it's effect on paintings. For those of you not familiar with it, it is 1:1.618+ or phi. supposedly if you use this ratio of 1 to phi in your composition it is supposed to supe up the appeal of it. According to testimony it makes a portrait look more like the person than the person does. Is there anyone who actively uses this in their work? I'm still playing with it, but I was wondering if there are any tips from those of you who are old pros, or maybe some good articles around the net. There was one in the artist's magazine, but it was too general to be helpful.
