Nikon D70, dirty dots on exposures

ok, first a question about those little blurry dots i get. they don't
stay long, they seem to move around, but when i make pictures with a
flat background, like the whole image is just a nice blue sky, i get
these blurry dots all over. sometimes up to 4-5. they stay for a while
and then new once apear somewhere else.

is it just a matter of cleaning the matrix?

any advice welcome

They are dust specks on your sensor.

For that price I can take the D-70 down to the local camera shop quite
a few times.

After nearly a year of shooting with a lot of outdoor photography in
hot dusty conditions I have only had dust spots show up once.

A little air and it was as good as new.

I don't stick anything in there.

Not to reprise the sensor swabbing thread, but I too have found that a
couple of blasts with a Giotto Rocket blower takes care of the majority of
sensor dust. I used to use PecPads/Eclipse, but now have gone entirely to
the Sensor Brush.

This photo is from a poster on DP Review and is an example of what happens
when you use TWO drops of Eclipse on a PecPad instead of ONE drop...

hey roger.

the only "real" camera store (apart from the ritz empire) is national camera
exchange, which refuses to sell any photographic solutions equipment and
charges 45 dollars for sensor cleaning. i could have ordered the stuff for
about 20 bucks from other places, but i decided to go with the kit as it
includes the swab that the author writes about and the instructions are
tweaked for.

i don't force anyone to try this, just sharing my experiences.
