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.

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.

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.

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.

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. JC --- John Christensen 1984 El Camino "Elkenstein" 350 TBI NECOA #042 http://www.myelcamino.net<http://www.myelcamino.net/> Saint Charles, IL
