Depth of field is a funny thing isn't it? The small aperture of the human eye means that in daylight at least, those of us with anything approaching 20:20 vision have items a few feet away and those on the horizon in sharp focus at the same time. There's no way I can open up my iris so that the seed heads in the foreground are in sharp focus whilst the pylon in the distance is as blurred as it is in this photo. Of course I can't think of any reason why we'd want to do such a thing. But for artistic reasons or to stress one part of an image it can be a very powerful effect of our camera lens. These Teazel seed heads are a favourite food for birds, particularly finches. Canon EOS 5D
