If you don't have anything white handy, use the sky. Nothing like the old sky
shot. A nice gray day like we have in Utah all winter works real good.

Thanks for the info.
I shot some close ups of my sliding diamond ring at work with it yesaterday
in the light box we have there. I didn't see anything noticeable, but I'll try
the white all trick this morning.

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.

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.
