Out Damn Spot!

While fiddling around with a few product photographs of some lens I may sell on eBay, I realized I have another 2 dust or water spots on my image sensor. This is the second time I've had a dust spots show up since I've had my D300. It's so aggravating - it's like an itch you can't scratch! These look exactly like the specks I had before - just in a different part of the frame. This time, they're way off to the right side of the frame (typically not the focus of the frame). I can't figure out how they're getting on there.

I may take it back to the repair shop that cleaned it last time. Maybe they can help me figure out what's causing them. I don't use the camera in a harsh environment. I don't change lenses that often. When I do, it's usually in a contained area. Whatever I do, I'm not taking it back to Ritz - they tried to clean it and blew more dust in it. Lesson #1 - Don't let the college kids from Ritz handle your new camera. So I ended up taking it to a place here in Jacksonville called Southern Photo Technical. The store felt more like a museum instead of a repair shop. Old projectors and old film camera items littered the store. I don't know how they stay in business.

If you have no idea what I'm talking about, here's a quick summary. Basically, DSLR camera sensors (where the film used to be) are susceptible to dust spots. Dust sneaks in while changing a lens and I think under heavy zooming (on big zooms). These spots show up only in certain exposure conditions. But when they show up - it'll drive you nuts...

Here's a link full of way too much detail, if you want to read more - I didn't.
