Here ya go, with pictures.

Taken at f/22 and f/16, MF-infinity and auto leveled- Cntrl+Shift+L on PS CS2. This shows you the scope of the NON problem.

Tools: CopperHill Imaging 14mm SensorSwipe (for APS-C sensors), Eclipse Cleaning Solution (Original not E2, E2 is for the cameras with self-cleaning ding dong), PecPads, scotch tape, giotto blower, some good old bollywood music and a relatively clean desk.

Put camera is sensor cleaning mode and squirted a few puffs of air using Giotto to dislodge any easily removable dust bunnies. And then did one sweep using the wet cleaning method

Can you see? Looks good, but not good enough. Can you see?

Second Pass and this time I cheated, I know from experince that most of the crud is swept to the edges of the frame, so I did the usual wet cleaning and I also cleaned the edges (in a rectangular, anti-clockwise manner) with a PecPad wrapped on a QTip. Can you see? I just messed it up even more? Look at the crud? Those streaks, that crud? OMG!!!

So I wrapped another PecPad on the sensor sweep and repeated the first pass. And this is what I got. I can live with this at f/16 (coz I don’t plan to shoot below f/8 over the coming weeks)

Its really that easy. Even a mathematician, statistician or even an Oracle can do it.
