Recently, I've noticed spots on my images. I knew my lenses were clean, what could it be?

After a long process of research and study, I figured out that the sensor on my camera was dirty.
I'm not shy about tackling this kind of thing on my own, I like to think I'm pretty good at it.
Heck, I've changed out drives, processors and memory on my computers over the years.
And I've done plenty of maintenance on my TV cameras and VTR's at work.

Cleaning the sensor on your DSLR yourself is not for the faint hearted.
It's a tricky process that can irreversably damage your camera if done improperly.
Don't try this unless you're absolutely certain you know what you're doing.

But I'm brave, so I tackled it... Everything went well.

But now I'm educated. I know there's no way to get the sensor perfectly clean.
I know I may not see it in my photos, but dust is still there.

And it's driving me nuts!
