Hi John,
Last year I had spots on my sensor (put there by Nikon's repair shop). I
took it in to a local camera store and they cleaned it, but they showed
me a neat way to check if the spots are gone, or if they are on the lens
(besides changing lenses that is)( and they also said, it is almost
always the sensor unless you spill chili on your lens).
Find a white wall with no seams or marks on it, set your exposure to
about 4 seconds, press the button and keep the camera in constant motion
to blur the picture. When you look at your blurry picture the only thing
that will be in focus are the spots on the sensor. It worked for me the
next time I got spots on the senor, but my in camera vibration cleaner
took care of those.
Anyway just a thought.
Larry

I have 2 pics attached. Looks like I'll have to try again. in the first
pic, I can see one spot at the pointer, and it's less visible than the 2
spots I had before. If I use the automatic level control on Photoshop.
it makes a lot more jump out at me. This is the same pic, with different
effects to show spots.
I'll have to try again after work.

I tried the procedure this morning. Need to go take a few pics of the
cloudy and raining sky to see if the dots are still there. Hopefully
less than there was before.
I am attaching a pic I never got around to sending a couple weeks ago.
This is of the roses after they had a chance to open some more. Taken on
about the 4th of January. Just a follow up, nad practice FWIW.
