The delicate graphs over low-contrast, well-shot photos are so beautifully subtle. And the typographer in me loves the equally understated equation captions.<p><a href="http://www.flickr.com/photos/nikkigraziano" rel="nofollow">http://www.flickr.com/photos/nikkigraziano</a>
Seems like a strange project to me. With just a little effort, you can really make equations that almost perfectly model any curve you find in a photograph.<p>What's so notable about this? I guess the pictures are pretty.
As an amateur photographer, I have often noticed how the best nature images are often of curves, or other geometrical shapes with some amount of symmetry. Lines that converge to the corners or lead the eye towards the intended focal point are another good example. Seeing function curves overimposed on natural curves tells the observer explicitly of the underlying harmony in nature and in math, which we all perceive, consciously or not.
