DSLR sensor chips collect dust. That is a Photoshop-time-consuming fact of digital life. At The Sun, whenever we send in our DSLRs to be otherwise repaired, one nice little bonus is that (along with the obscene repair bill) they come back with a freshly cleaned CCD.
Which, of course, lasts for about a week. Two if you are lucky.
You may not even notice that you have dust at all, until you stop down and shoot with a wide lens or macro. Then, all of a sudden it looks like you are looking through an electron microscope or something. Eww.
Heck, I used to even keep a little sticker on one of my bodies to denote which one had the “cleaner” (and I use the term in the relative sense) CCD. That was so I would know which one to use if I needed to shoot something at f/11 or higher.
