I seem to be unable to get my Nikon D90 DSLR to adjust aperture settings no matter what program I use. Have tried the A, M and P but no matter how I set it I end up with a full focussed frame and the camera only seems to recognise shutter speed settings. I'm trying to achieve a blurred background and have tried 3 different lenses, turning off AF and fiddling with every program on the camera! I'm guessing I'm missing something simple!
