I realised that the name Group f11 may seem a little arbitrary to some. Like Group f64 (founded by the likes of Ansel Adams, Edward Weston etc.) it derives its meaning from a technical application of the aperture. For Group f64 it was the aperture that gave the greatest detail, front to back, for an 8x10 inch negative.
F11 is, for most APS-C sized digital sensors the smallest aperture that allows maximum depth of field before the 'circle of confusion' rears its ugly head (Neil, this doesn't apply for you in a way as the FF sensor can handle a smaller aperture by about a stop). i had also thought about using f5.6 since that is usually the sharpest aperture on most 35mm format lenses. F11 it is though since we tend to want DoF as well as sharpness.
That, in a nutshell, is why this is called Group f11.

Maybe I just need to up my medication, but is anyone else bothered that the group is called f11 and there are four trees on the main header image? What is wrong with f4? It also, I think, has a ring of angry assertion to it (the f4 part). Random is random!
11 trees wouldn't fit in the banner :| , but more medication might help - then you can see more trees anyway and it won't be so random
