I just took some pics of the sky with clouds to photoshop into another shot. I found in each pic of the sky to have a few small (pea sized) darker blue dots on my pics. I reformatted two different cards and cleaned and tried two different lenses still the same problem. do you think this is bad pixels or just dirt on cmos

Either they are UFO's or dust on the sensor...

Classic (and normal) dust on the sensor. Most popular method for removal is by way of a blower.

It's just a few specks of dust on the sensor. You probably wouldn't even notice it accept that you're shooting at smaller apertures (higher f/stop numbers) against the sky (where it's more visible).

Try using a rubber bulb and if it's loose, you may be able to blow it off (but make sure your not sucking in dusty air when you use one, since you don't want to make it worse).

If that doesn't work, search for dust using the forum search feature,and you'll find threads discussing lots of options for cleaning the sensor (visible dust, copper hill method, etc.).
