Sensor - Test Shot

I purchased my Canon 7D in Sept '09 and today I took this shot of the sky to look for dust spots.

I could not see any spots, maybe my settings are wrong for a test like this.

ISO100
F2.8
1/5000 second

Yes, they are wrong. Shoot at f/22.

^^^+1^^^

This photo was shot @ f/32

I looked at different sites and they stated shoot at f/32 if possible

ISO 100, f/32, 1/40 second

Looks good..

Damn, mine doesn't look that clean at 2.8!

My monitor is dirtier than your sensor. Time for a cleaning.

That's the same image.

Are you familiar with the pros and cons of using aRGB colour-space?

^^ That is definitely the same image and there is little chance that any one here viewing it at that resolution can determine if your sensor is actually clean.

The exif data has been removed from that shot for some reason.

But if it is f/32, run auto-levels and it's the cleanest sensor I've ever seen

Yes, looks like the same image, but where is the camera data? It does look like a test-shot at f/2.8.

Photo Bucket is playing around with my images they are not in order of hope I uploaded.

You 've got a few dustbunnies...

Yes, you do have some specks as seen in the shot by MakisM1 above. To get the screen he has shown you, use auto-levels in Photoshop. You might want to try something like the Rocket Blower to try blowing off the specks, but if you can't see them at f/32, then you probably can wait on doing a more thorough cleaning.
