I've read that a smaller aperture will increase depth of field, and the recommendation was f/16 - f/22 for landscapes. This seems too much for my camera (D90) and almost always produces the 'woolly' look I dislike.
Could anybody shed any light on what sort of settings would maximise depth of field with the clarity I'm after? I'm fully aware there isn't a blanket 'rule of thumb' that covers every and any situation, but I think if I had a better understanding of aperture settings where landscape photography is concerned I'd stand a better chance of being able to tweak the camera settings to suit the occasion.
Edit: From what I've been reading I think it's something known as defraction that's causing the problem I'm clumsily attempting to explain.

Diffraction happens once you go smaller than F11-Diffraction is where light rays enter a small opening(aperture),overcrowding to get through occurs,so rays that don't immediately get through bounce around between lens elements and diaphragm blades,and even ones that do squeeze through interfere with other rays,causing blurring.(Diffraction) Although smaller apertures do give a deeper depth of field,diffractionaffects sharpness-It's a trade-off.
