then and go outside and take a
picture of a flat sky - blue is best but plain old solid cloud cover
will do just as well. Download the picture and have a good look at
it - if there are still spots caused by dust, do it all over again if
necessary.
One tip: you should take this test picture with as small an aperture
as possible, f22 for instance. This will show all dust and dirt,
even on the LCD-screen.
Believe me dust like this is a pain - if you get it down to a single
small blob you might do better to leave it there and paint it out
afterwards - generally speaking you won't see it/them unless you are
looking at a large-ish area of saturated light colour. If you manage
to get dust free, thereafter try to avoid lens changing - but if you
must always do it indoors where there is no draught, and keep the
(open) lens aperture facing downwards at all times.
Even with no lens changes the dust finds it way. Especially the
big zoomlenses which have a big volume-change when zoomed
from fully wide-angle to fully tele act as a dust-pump, pumping
air and dust into the camera body.
My experience is: 80% of the dust can be blown away with
compressed air. Another 10% can be wiped off with these
sensor swabs, and there's another 10% that's so stuck that
they won't be removed easily. These are for instance tiny
oil drops from the shutter.
