One tip i think i gave the OP and he found it worked
stand opposite an window or patio door, move as far away from it as you can still see out of it, note what you see

then walk towards it stop and note what you can see,
then get to the door/window note your view this is how a camera lens works trust me it helps figure out what your doing

another thing to remember with SLR is if the lens length is say 100mm then your shutter speed needs to be 100 to stop blur, always try and keep ISO at 200 and your JPEG settings as medium/high
