... root 2, that is 1:1.41 isn't of any real application other than it's the ratio of the A-size papers A4 being 210x297, A3 297x420 and so on ... phi, is the golden ratio at 1:1.62 both are irrational constants from the Classical Era ... that is Greece BC 500 to 300-ish
Both being close enough to 1:1.5 is missing the point it's like claiming 3 is close enough pi not to matter
Your third paragraph is a very pertinent observation ... although I suspect he would be looking for Gestalt rather than Classical composition
Hi Stewart,
Here is one of my favourite photos taken by Henri Cartier-Bresson. I believe that HC-B used his knowledge of the Root-2 rectangle to compose this image. I've overlaid the Root-2 rectangle in red and as you can see it doesn't cover the entire 1:1.5 rectangle. However, I think its pretty damn good!

SPAIN. Valencia Province. Alicante. 1933.
With all due respect, if the Root-2 was close enough for HC-B, it is close enough for me!
The Golden Rectangle also doesn't cover the entire 1:1.5 frame either. The short edges can get cut off with a Root-2 as in the above image. With the Golden Rectangle, the edges on the long side can get cut off.
To demonstrate, and also to show that I actually use this stuff, here is one of my humble photographs.

When I was looking through the viewfinder, I was actually trying to line things up on the whirling squares of the golden rectangle.

It took me perhaps 10 minutes or so to figure out how to set up the shot. However, I was very familiar with this place and I had a picture like this in my mind's eye for some time. After I waited a while, the barristas entered the frame and I started shooting. I took about 6-8 shots and this was the one that worked the best. Its not perfect, not exact but I don't think I could have done much better given the circumstance and my current skill-set.
